Description

Color black photosensitive resin composition and black matrix prepared by using same

The present invention relates to a color black photosensitive resin composition, a black matrix and a color filter made therefrom, and more particularly, a color black photosensitive resin composition capable of forming a pattern of improved straightness. Objects, and the black matrix and color filters made therefrom.

The black matrix in color filters for liquid crystal displays is used to block uncontrolled light transmitted outside the transparent small electrode, thereby improving light contrast. The black matrix is made of a material such as chromium or resin. For chromium, the film has excellent light-shielding properties and pattern straightness. However, due to environmental problems, high reflectance, and high processing costs, it is preferable to use a resin-based black matrix. However, with respect to a photosensitive resin composition for manufacturing a resin-based black matrix, photocrosslinking cannot occur effectively due to a black pigment that significantly suppresses photosensitive characteristics. Further, there are problems such as excessive erosion by a developer (referred to as "undercut"), lack of development stability, reduction in light sensitivity, and the like. Korean Patent Application No. 1995-7002313 discloses a photosensitive resin composition that is a black matrix using a caldo resin to improve sensitivity. However, caldo resin has a huge molecular structure and reduces adhesion. In particular, for a black matrix, the content of a black pigment is increased to obtain a desired optical density, thereby significantly reducing adhesion. Therefore, Korean Patent Publication No. 2000-0055255 discloses a Kaldor resin including a copolymer of different monomers and a silane coupling agent. However, the above-mentioned invention relates to deteriorated storage stability, and it causes a problem that a position-dependent difference in optical density occurs when a fine pattern is formed by heat flow during post baking. At the same time, as the pattern is formed more finely, the shape of the pattern (specifically, the straightness of the pattern) becomes more important. In this regard, if the thermal fluidity of the resin used for the photosensitive resin composition is reduced in order to reduce the difference in optical density depending on the position, this causes a problem that the pattern straightness is reduced. No technique has been disclosed that can simultaneously improve the straightness of the pattern and reduce the difference in optical density that forms the pattern.

An object of the present invention is to provide a color black photosensitive resin composition having excellent pattern straightness and reducing a difference in position-dependent optical density. Meanwhile, another object of the present invention is to provide a color black photosensitive resin composition capable of forming a micro-pattern and having excellent storage stability and sensitivity. The above object of the present invention will be achieved by the following features: (1) A color black photosensitive resin composition, including: (A) a colorant, (B) an alkali-soluble resin, (C) a photopolymerizable compound, (D ) A photopolymerization initiator, and (E) a solvent wherein (A) the colorant includes an i-beam transmittance of 0.3 or more having a primary particle diameter of 20 to 60 nm and an OD value of 1.5 or Higher carbon black, and the alkali-soluble resin (B) are polymerized from monomers including monomers represented by the following Chemical Formula 1: [Chemical Formula 1]

(Where n is an integer from 2 to 4).

(2) The composition according to (1) above, wherein the primary particle diameter of the carbon black ranges from 30 to 45 nm.

(3) The composition according to the above (1), wherein the single system represented by Chemical Formula 1 is included in an amount of 10 to 40 wt. Part to 100 wt. Part of the total monomer.

(4) The composition according to the above (1), wherein the alkali-soluble resin (B) is polymerized from a monomer, and further contains a monomer represented by the following Chemical Formula 2:

(Where m is an integer from 0 to 2).

(5) The composition according to the above (4), wherein the single system represented by Chemical Formula 2 is included in an amount of 10 to 40 wt. Parts relative to 100 wt. Parts of the total monomers.

(6) A black matrix made of the color black photosensitive resin composition according to any one of the above (1) to (5).

(7) A color filter including the black matrix according to the above (6).

(8) An image display device including the color filter according to the above (7).

The color black photosensitive resin composition of the present invention includes a polymer resin containing a specific monomer to achieve very excellent fine pattern formation performance and low thermal fluidity, thereby reducing the position-dependent optical density difference. Therefore, it is possible to manufacture a black matrix capable of uniformly blocking a strong backlight.

In addition, the color black photosensitive resin composition of the present invention includes a specific carbon black to solve the problem of lowering the pattern straightness that may be caused by low thermal fluidity, thereby ensuring excellent pattern straightness while reducing position-dependent optical Density difference.

In addition, the color black photosensitive resin composition of the present invention has excellent storage stability and therefore does not involve changes in physical properties during storage for a period of time, but exhibits excellent sensitivity.

The invention discloses a color black photosensitive resin composition comprising: (A) a colorant, (B) an alkali-soluble resin, (C) a photopolymerizable compound, (D) a photopolymerization initiator, and ( E) a solvent, wherein the (A) colorant includes carbon black having a primary particle diameter of 20 to 60 nm and an i-beam transmittance of 0.3 or higher when the OD value is 1.5, and an alkali The soluble resin (B) is polymerized from a monomer and contains a monomer represented by the following Chemical Formula 1, thereby reducing a position-dependent optical density difference and achieving excellent pattern straightness.

Hereinafter, the present invention will be described in more detail.

<Color black photosensitive resin composition>

The color black photosensitive resin composition of the present invention may include (A) a colorant, (B) an alkali-soluble resin, (C) a photopolymerizable compound, (D) a photopolymerization initiator, and (E) a solvent. . Of course, any additional composition commonly used in the related art, such as an additive, may be further included without particular limitation.

<(A) Colorant> The colorant according to the present invention may include carbon black as a key component, wherein the carbon black has a primary particle diameter of 20 to 60 nm and an optical density (OD) value (optical concentration) At 1.5, an i-beam transmittance of 0.3 or higher. When the above carbon black is used, a uniform OD value and excellent sensitivity can be achieved at the same time. In particular, the pattern straightness can be significantly improved by improving the thermal fluidity of the resin, which will be described in more detail below. In general, UV light that is irradiated to a color black photosensitive resin composition may include, for example, a combination of different emission beams with respect to a wavelength of light emitted from an exposure device, such as a g-type beam (436 nm), an h-type Beams (405 nm), i-beams (365 nm), j-beams (330 nm), k-beams (310 nm), etc., are related to the polymerization initiation efficiency of the photopolymerization initiator. In other words, the sensitivity of the color black photosensitive resin composition is significantly related to the transmittance of the different emission beams (g, h, i, j, and k beams) to the color black photosensitive resin composition. However, the OD values of black matrices traditionally used range from 2 to 5. Therefore, in order to accurately measure the transmittance (with the OD value in the visible wavelength range (400 nm to 780 nm) set to 1.5), when using the UV light transmittance, a more precise transmittance value can be obtained. Therefore, in order to achieve sufficient sensitivity at a wavelength as described above, when the OD value of the color black photosensitive resin composition is controlled at 1.5, the color black photosensitive resin composition may have an i-beam transmittance of 0.3 or more, and It is preferably 0.4 or higher, and more preferably 0.5 or higher. If the i-beam transmittance is lower than the above value, sensitivity may be reduced. Further, the j-beam is also related to the initiation of polymerization of the photopolymerization initiator, and its transmittance may be 0.15 or higher, and preferably 0.3 or higher. Similarly, the k-type beam is also related to the polymerization initiation of the photopolymerization initiator, and its transmittance may be 0.05 or higher, and preferably 0.1 or higher. Regarding the color black photosensitive resin composition of the present invention, (A) the colorant, that is, carbon black may have a primary particle diameter in a range of 20 to 60 nm so as to have a desired UV light transmittance. Further, the lower limit value of the primary particle diameter of carbon black may be 30 nm or higher, and the upper limit value of the primary particle diameter of carbon black may be 45 nm or lower. Regarding the color black photosensitive resin composition of the present invention, if the primary particle diameter of the carbon black is less than 20 nm, the irradiated UV light has a low transmittance and cannot provide sufficient sensitivity. Further, it is difficult to uniformly disperse the carbon black in the color black photosensitive resin composition, and thus it may not be possible to obtain a uniform OD value. On the other hand, when the primary particle diameter of the carbon black is 20 nm or more, sufficient UV light transmittance can be obtained, thereby providing desired sensitivity and improving dispersibility at the same time. As a result, a color black photosensitive resin composition capable of providing a uniform OD value can be obtained. Further, the use of carbon black having a primary particle diameter of 30 nm or higher can achieve a further higher UV light transmittance, thereby enhancing photosensitivity and further improving dispersibility. Therefore, it is possible to obtain a color black photosensitive resin composition capable of providing a more uniform OD value. In addition, regarding the color black photosensitive resin composition of the present invention, when the primary particle diameter of the carbon black exceeds 60 nm, although sufficient UV light transmittance is reached, the carbon black precipitates in the color black photosensitive resin composition, causing uniform dispersion therein. difficult. Further, it is difficult to form a black matrix in its favorable form using the color black photosensitive resin composition due to an increase in roughness. On the other hand, when the carbon black has a primary particle diameter of 60 nm or less, sufficient UV light transmittance can be achieved to thereby obtain desired sensitivity and further improve dispersibility. In addition, when the carbon black has a primary particle diameter of 45 nm or less, sufficient UV light transmittance can be achieved to thereby obtain a desired sensitivity and further improve dispersibility, and thus it is possible to easily handle it during the manufacturing process . Generally, in order to maintain a high-contrast image in a black matrix formed using a color black photosensitive resin composition, it is desirable to have an OD value of 1.5 or higher, preferably 3.0 or higher, and more preferably 4.0 or higher. Light shielding rate. At the same time, after curing and developing the black photosensitive resin composition, the pattern interface is generally non-uniform, and the pattern has a pattern bottom (on the contact side with the substrate) that etches more structures than the pattern top, That is, an inverted cone structure. The interface of the above-mentioned pattern can be made uniform due to the thermal fluidity of the resin in the subsequent post-baking process, and then, this cone can have a forward-tapered structure, thereby ensuring the straightness of the pattern. Therefore, when the alkali-soluble resin used for the photosensitive resin composition has low thermal fluidity, it may cause a problem of reducing the straightness of the pattern. The alkali-soluble resin according to the present invention described below also exhibits low thermal fluidity, and when it is used alone, the pattern straightness may decrease. However, when a carbon black having a specific particle size range according to the present invention is used, it is possible to improve the thermal fluidity of the pattern to thereby improve the straightness of the pattern. When the particle diameter exceeds the above range, the effect of improving the straightness of the pattern may not be achieved. To the extent not departing from the object of the present invention, in addition to the carbon black described above, the colorant of the present invention may further include typical pigments and dyes used in the related art.

However, considering the development of a color black photosensitive resin composition prepared in the form of a pigment dispersion composition, a resin having an acid value may be used to achieve solubility in an alkali developing solution. Here, the acid value is a measurement value of the amount (mg) of potassium hydroxide required to neutralize 1 g of the acrylic polymer, and in general, it can be calculated via titration using a potassium hydroxide solution. The dispersion resin having an acid value can be prepared by copolymerizing a compound (b1) having an unsaturated bond accompanying a carboxyl group and a compound (b2) having an unsaturated bond copolymerizable with the compound (b1).

The compounds exemplified as the compound (b2) may be used alone or in combination of two or more thereof, respectively. In terms of solid content, the dispersing resin may be included in the colorant in an amount of 5 to 60 parts by weight, preferably 10 to 50 parts by weight for 100 parts by weight. If the content of the dispersion solvent exceeds 60 parts by weight, the viscosity may increase due to the dispersion resin. If the amount of the dispersed resin is less than 5 parts by weight, the amount of the dispersed resin is insufficient, and thus a micronized pigment dispersion composition may not be obtained. (a6) Dye The dye may include any one without particular limitation as long as it has solubility in an organic solvent. In particular, it is preferable to use a dye having solubility in an organic solvent while ensuring reliability such as solubility, heat resistance, and solvent-resistance to an alkaline developer. The dye may include, for example, any one selected from: an acid dye having an acidic group (such as a sulfonic acid or a carboxylic acid); a salt of an acid dye with a nitrogen-containing compound; an acid dye Sulfamethoxamine; and any of its derivatives. In addition to the above, acid dyes based on azo-, xanthenes-, or phthalocyanine-, and derivatives thereof can also be selected.

In terms of the solid content of the present invention, the (A) colorant may be contained in an amount of 20 to 80 wt.%, Preferably 35 to 70 wt.%, Of the total weight of the color black photosensitive resin composition. <(B) Alkali-soluble resin> The alkali-soluble resin may have light or heat activity and alkali solubility, and may be reactive as a dispersion solvent for individual components in the composition of the present invention. The alkali-soluble resin of the present invention can be polymerized from a monomer including a monomer represented by the following Chemical Formula 1. [Chemical Formula 1] (Where n is an integer from 2 to 4). The monomer represented by Chemical Formula 1 can improve the adhesion between the resin composition of the present invention and the substrate, and the polymerized resin is non-reactive and has improved storage stability, and therefore does not exhibit a line width depending on the storage time ( line width). Further, the thermal fluidity during post-baking is low, and the difference in optical density depending on the position may be improved, thus enabling the production of a black matrix that can evenly block the backlight. The compound represented by the above Chemical Formula 1 may include, specifically, acryloxyethyl succinate or the like. Preferably, it is selected from the group consisting of 4- (2- (propenyloxy) ethoxy) -4-oxobutanoic acid, 5- (2- (propenyloxy) ethoxy) -5-oxovaleric acid, and Any one of the group consisting of 6- (2- (propenyloxy) ethoxy) -6-oxohexanoic acid may be used alone or as a mixture thereof, but it is not particularly limited thereto. The monomer represented by the above Chemical Formula 1 may be included in an amount of 10 to 40 parts by weight to 100 parts by weight of the entire monomer, which is introduced for polymerization of the alkali-soluble resin (B). If the single system represented by Chemical Formula 1 is contained in an amount of less than 10 parts by weight, the effect of reducing thermal fluidity during post-baking may not be significant during pattern formation. Further, the straightness may become poor due to the generation of a residual layer during pattern formation. In other aspects, when the above amount exceeds 40 parts by weight, it may not be possible to obtain the desired straightness and film uniformity due to the phenomenon of sedimentation during pattern formation. Further, the alkali-soluble resin (B) according to the present invention may be polymerized from a monomer optionally including a monomer represented by the following Chemical Formula 2. [Chemical Formula 2] (Where m is an integer from 0 to 2).

The monomer represented by Chemical Formula 2 may include, in particular, isobornyl methacrylate. Preferably, it is selected from the group consisting of 1,7,7-trimethylbicyclo [2.2.1] hept-2-ylmethacrylate, 7,7-dimethyl-1-propylbicyclo [2,2,1 ] Hept-2-yl methacrylate, 1-ethyl-7,7-dimethylbicyclo [2.2.1] hept-2-yl methacrylate and 1-ethyl-7,7-dimethyl Any one of the groups consisting of the bicyclo [2.2.1] methacrylate may be used alone or in a mixture thereof, but it is not particularly limited thereto. The compound represented by the above Chemical Formula 2 may be included in an amount of 10 to 40 parts by weight with respect to 100 parts by weight of the entire monomer. If the amount is less than 10 parts by weight, the adhesion is weak during pattern formation. When the amount exceeds 40 parts by weight, the developing effect is reduced, and at the same time, the adhesion to the substrate is increased, which causes difficulty in forming a fine pattern. The alkali-soluble resin according to the present invention may be polymerized from a monomer further including a monomer having an unsaturated bond capable of copolymerizing with the monomer represented by Chemical Formula 1 or Chemical Formula 2. In particular, it is selected from the group consisting of a (meth) acrylate compound (here, the (meth) acrylate includes both (meth) acrylate and acrylate), an aromatic vinyl compound, a vinyl carboxylate compound, a cyanide Vinyl compound, maleimide compound, vinyl carboxylic acid ester compound, unsaturated oxetane carboxylic acid ester compound, unit carboxylic acid ester compound, dicarboxylic acid ester compound, and each having Any one of the group consisting of a compound of a carboxyl group and a hydroxyl group may be further contained alone or as a mixture thereof.

Specific examples of the carboxylic acid vinylester compound may include vinyl acetate or vinyl propionate, but it is not particularly limited thereto. Specific examples of the cyanide vinyl compound may include acrylonitrile, methacrylonitrile, or α-chloroacrylonitrile, but it is not particularly limited thereto. Specific examples of the maleimide compound may include N-cyclohexylmaleimide or N-phenylmaleimide, but it is not particularly limited thereto. Specific examples of the vinyl carboxylate compound may include vinyl acetate or vinyl propionate, but it is not particularly limited thereto.

Specific examples of the unit carboxylic acid compound may include acrylic acid, methacrylic acid, crotonic acid, or the like, but it is not particularly limited thereto. Specific examples of the dicarboxylic acid ester compound may include fumaric acid, mesaconic acid, or itaconic acid, but it is not particularly limited thereto. Specific examples of each compound having a carboxyl group and a hydroxyl group at both ends thereof may include ω-carboxy polycaprolactone, mono (meth) acrylic acid, and the like, but it is not particularly limited thereto. If necessary, the alkali-soluble resin of the present invention may further include various alkali-soluble resins known and generally used in the related art by mixing it with the resin of the present invention. In the case of polystyrene, the alkali-soluble resin may have a weight average molecular weight of 3,000 to 100,000, preferably 5,000 to 50,000. If the weight-average molecular weight of the alkali-soluble resin exceeds the above-mentioned range, the reduction of the film during the development and the omission of the pattern portion cannot be avoided. The acid value of the alkali-soluble resin may range from 20 to 200 (KOH mg / g), preferably 60 to 140 (KOH mg / g), more preferably 80 to 135 (KOH mg / g), and most preferably 80 To 130 (KOH mg / g). If the acid value ranges from 20 to 200 (KOH mg / g), the solubility of the developer can be improved, and the residual layer rate can also be increased. In this regard, the acid value means the amount (mg) of potassium hydroxide required to neutralize 1 g of the acrylic polymer, and in general, it can be calculated via titration using a potassium hydroxide solution. In terms of the solid content of the present invention, the above-mentioned alkali-soluble resin may be included in an amount of 10 to 80 wt.%, Preferably 10 to 70 wt.%, Based on the total weight of the color black photosensitive resin composition. Within the above range, the solubility of the developer is sufficient to easily form a pattern, and it is possible to avoid a reduction in the film in the pixel portion of the exposed portion during development, and thus to advantageously protect the non-pixel portion without omission. <(C) Photopolymerizable compound> The photopolymerizable compound contained in the color black photosensitive resin composition of the present invention means a compound capable of living polymerization with light and a photopolymerization initiator to be described below, and may include a monofunctional , Bifunctional and / or other multifunctional monomers.

<Synthesis Examples 1 to 20> Synthesis of alkali-soluble resin

In a 1000 ml flask equipped with a stirrer, a thermometer, a reflux cooling tube, a drip dispenser, and a nitrogen introduction tube, propylene glycol ether acetate (PGMEA), AIBN, and 2-propylene were introduced in the amounts listed in Tables 3 and 4 below Ethoxyethyl succinates (B-1), N-phenylmaleimide, styrene, methacrylic acid, and isobornyl methacrylate (B-2), followed by nitrogen substitution ( The units of numerical values shown below in Tables 3 and 4 are grams). Thereafter, the temperature of the reactant was increased to 100 ° C. while stirring, and then the reaction was performed at the elevated temperature for 7 hours. For the synthetic alkali-soluble resin, the final solid content, the acid value of the solid content, and the weight average molecular weight were measured by GPC. The results are shown in Tables 3 and 4 below. The B-1 and B-2 used in each synthesis example are shown in Table 2 below.

<Example 1-13> A photosensitive resin composition for black color to the table shown in the following table 5 and 6 in the basic composition was prepared color black photosensitive resin composition. The numerical units shown in Tables 5 and 6 below are in grams. <Comparative Example 1-7> Preparation of a photosensitive resin composition of the black color in the black table are listed in the following photosensitive resin composition consisting essentially of 7 was prepared in color. The values in Table 7 below are expressed in grams. < Experimental Example 1> Evaluation of thermal fluidity After each color black photosensitive resin composition prepared in Examples 1 to 13 and Comparative Examples 1 to 7 was coated on a glass substrate, the coated substrate was placed on The plate was heated and maintained at a temperature of 100 ° C for 2 minutes to form a thin film. Next, a test mask having a stepwise change in transmittance in the range of 1 to 100%, and a pattern in the range of 1 μm to 50 μm line / space was placed on the film, and then the test mask was placed between the test mask and the film. UV irradiation was performed at a distance of 50 μm. In this regard, a 1 KW high-pressure mercury lamp containing all g, h and i beams was used as a UV light source to emit light with a radiation intensity of 50 mJ / cm ² . No special optical filters are used. The UV-irradiated film was immersed in a KOH water-soluble developer at pH 10.5 for 2 minutes to develop it. After the glass substrate coated with the above-mentioned film was washed with distilled water, it was dried by blowing with nitrogen gas, and then heated at 230 ° C. for 20 minutes in a heating furnace to manufacture a color filter. The thickness of the manufactured color filter film was 1.0 μm. In the exposed portion remaining after the development, the film thickness of the 20 μm pattern was measured before and after the post-baking, and was used to measure the thermal fluidity according to the following formula. The measured results were evaluated according to the following evaluation criteria and shown in Table 8 below. * ○: more than 97%, △: 95-97%, X: less than 95% As shown in Table 8, it can be seen that the color black photosensitive resin composition in the example showed a decrease in thermal fluidity and no significant change in the film thickness before and after the post-baking. On the other hand, the color black photosensitive resin composition prepared in the comparative example exhibits high thermal fluidity, thereby causing a difference in film thickness before and after post-baking. < Experimental Example 2> Evaluation of storage stability was followed by standard samples and each color black photosensitive resin composition for light shielding prepared according to Examples 1 to 13 and Comparative Examples 1 to 7 at 25 ° C. Each sample prepared on the 5th, 3rd, and 1st day was placed on a glass substrate by a spin coating method before the experiment for evaluating the pattern. The coated substrate was placed on a hot plate and maintained at a temperature of 100 ° C for 2 minutes to form a thin film. Next, a test mask having a 20 mm pattern was placed on the film, and then UV irradiation was performed at a distance of 50 μm between the test mask and the film. In this regard, a 1 KW high-pressure mercury lamp containing all g, h and i beams was used as a UV light source to emit light with a radiation intensity of 50 mJ / cm ² . No special optical filters are used. The UV-irradiated film was immersed in a KOH water-soluble developer at pH 10.5 for 2 minutes to develop it. After the glass substrate coated with the thin film was washed with distilled water, it was dried with a nitrogen blow, and then heated at 230 ° C. for 20 minutes in a heating furnace to manufacture a color filter. For the manufactured color filter, the line width of a pattern formed on a mask having a line width of 20 mm was measured. Using the measurement value, measure the line width change (△ CD) with respect to the placement time. The measurement results are shown in Table 9 below. △ CD = pattern line width measured using the resin composition prepared on the day-pattern line width measured using the resin composition placed at room temperature ○: △ CD = 0.5 mm or less △: △ CD = 0.5-1.0 mm ×: △ CD = 1.0 mm or more As shown in Table 9 above, the color black photosensitive resin composition in the example does not have a pattern line width difference due to the composition being left at room temperature. However, the composition in the comparative example began to show changes in the pattern line width after being left for 3 days. < Experimental Example 3> Evaluation of fineness and sensitivity After coating each color black photosensitive resin composition prepared in Examples and Comparative Examples on a glass substrate, the coated substrate was placed on a hot plate and maintained The temperature was 100 ° C for 2 minutes to form a thin film. Next, a test mask having a pattern with a variation of 2 mm to 20 mm in units of 1 mm was placed on the film, and then UV irradiation was performed at a distance of 50 μm between the test mask and the film. In this regard, a 1 KW high-pressure mercury lamp containing all g, h and i beams was used as a UV light source to emit light with a radiation intensity of 50 mJ / cm ² . No special optical filters are used. The UV-irradiated film was immersed in a KOH water-soluble developer at pH 10.5 for 2 minutes to develop it. After the glass substrate coated with the film was washed with distilled water, it was observed with an optical microscope to determine what pattern's mm size remained on the film, and the observation results are shown in Table 10 below. ○: A pattern of 4 mm or less was observed. △: A pattern of 4-6 mm was observed. X: A pattern of 6 mm or more is observed. By participating in the above Table 10, it can be seen that the compositions in the examples generally have superior pattern fineness and sensitivity compared to those in the comparative example. Specifically, in addition to Example 4, which contains a small amount of a monomer represented by Chemical Formula 1 or 2, showing a slightly reduced fineness and sensitivity, most of the film has a pattern of less than 4 mm remaining thereon. , So the example achieves very good sensitivity. < Experimental Example 4> Evaluation of Pattern Straightness After performing the same procedure as described in Experimental Examples 1 to 3 until the development procedure, the product was washed with distilled water through an ultra-high pressure cleaning procedure (2 MPa) for 10 seconds. Thereafter, pattern peeling was observed with an optical microscope and straightness was evaluated according to the following criteria. The evaluation results are shown in Table 11 below. ：: When a 10 mm pattern is measured, the size of the raised or peeled portion is 0.5 mm or more, and the number thereof is 1 or less. Δ: When a 10 mm pattern is measured, the size of the raised or peeled portion is 0.5 mm or more, and the number thereof is 2 or more, but less than 5. X: When measuring a 10 mm pattern, the size of the raised or peeled part is 0.5 mm or more, and the number thereof is 5 or more. Referring to Table 11 above, it can be seen that the composition in the example has an excellent pattern straightness compared to those in the comparative example.
