Description

  The present invention relates to a pressure-sensitive transfer correction tape used for concealing and correcting characters or the like that are erroneously recorded on paper. Specifically, the present invention relates to a pressure-sensitive transfer correction tape having excellent hiding power and a small difference in color between the front and back of the tape.

  Conventionally, when erasing and correcting writing lines that cannot be erased with an eraser written with a ballpoint pen, fountain pen, sign pen, typewriter, etc., or printed lines, copy lines drawn with PPC copies, etc., they are covered and concealed. A pressure-sensitive transfer correction tape that can be corrected by rewriting is used.

  A pressure-sensitive transfer correction tape generally has a multilayer structure in which a concealing layer containing a white pigment and a pressure-sensitive adhesive layer are laminated in this order on one side of a substrate. Such a pressure-sensitive transfer correction tape is usually used in a state of being wound in a roll and loaded in a transfer tool that also serves as a holder.

  In such a pressure-sensitive transfer correction tape, it is important to have a concealing power such that when characters and strokes are covered and concealed, the characters and the like cannot be seen through. In order to improve the hiding power of the pressure-sensitive transfer correction tape, there are methods of increasing the amount of white pigment added to the hiding layer or increasing the film thickness of the hiding layer. However, from the viewpoint of handleability of the pressure-sensitive transfer correction tape, it is desired to make the film thickness thinner.

  As a method for improving the hiding power while reducing the film thickness of the hiding layer, it has been proposed to contain a non-white pigment such as carbon black in the hiding layer. However, the hiding power increases as the content of the non-white pigment increases. However, if the content of the non-white pigment is too large, the appearance of the tape appears to be colored in the color of the non-white pigment. There was a problem that it was mistakenly recognized.

  As a method for increasing the hiding power without affecting the “whiteness” of the tape, Patent Document 1 discloses a method of dispersing a non-white pigment between the hiding layer and the pressure-sensitive adhesive layer or in the pressure-sensitive adhesive layer. Proposed. However, even in the method of Patent Document 1, the pressure-sensitive adhesive layer side surface appears to be colored in a non-white pigment, and the pressure-sensitive transfer correction tape is viewed from the pressure-sensitive adhesive layer side. In addition, there was a problem that it was mistakenly recognized as a colored tape. As described above, there is still room for improvement in order to obtain a pressure-sensitive transfer correction tape in which the thickness of the hiding layer is reduced and the excellent hiding power and appearance are both compatible.

(Base material)
The base material used in the pressure-sensitive transfer correction tape of the present invention is not particularly limited as long as it is generally used as a base material for a pressure-sensitive transfer correction tape, and is transparent, for example, a plastic film or the like. Can be mentioned. Examples of the plastic film include polyethylene terephthalate (PET) film, polyester film such as polyethylene naphthalate film, polyolefin film such as polyethylene film and polypropylene film, polycarbonate film, polyacryl film, polystyrene film, etc. From the viewpoint of high strength, a polyester film is preferable, and a polyethylene terephthalate film is more preferable.

  As thickness of a base material, Preferably it is 3-25 micrometers, More preferably, 4-18 micrometers is mentioned. If the thickness of the substrate is too thin, the productivity at the time of processing such as mold release may be reduced. Moreover, when the thickness of a base material is too thick, there exists a possibility that lengthening may become difficult.

(Release layer)
The release layer provided on one or both sides of the substrate is a release agent consisting of silicone resin, fluorine resin, etc., or a release modifier, catalyst, additive, inorganic / organic fine particles, etc. mixed with the release agent. It is provided by applying and drying. The same release layer may be laminated on both surfaces of the substrate, or different release layers may be laminated as necessary.

  Although it does not specifically limit as thickness of a mold release layer, 0.05-3.0 micrometers, Preferably 0.1-1.0 micrometer is mentioned.

(Hidden layer)
The concealing layer is composed of a binder resin, a white pigment and / or a white extender pigment.
As the binder resin used for the masking layer, urethane-based, acrylic-based, vinyl-based, olefin-based, rubber-based resins, or the like can be used alone or in combination of two or more. In particular, a combination of a rubber-like resin and a glass-like resin can be suitably used since the balance between flexibility and cutting property of the masking layer coating film is good. The rubber-like resin preferably has a flexibility even if it contains only a small amount of plasticizer. For example, a styrene-butadiene-styrene block copolymer (SBS), a styrene-ethylene-butylene-styrene block copolymer ( SEBS), styrene-butadiene rubber (SBR), styrene-isoprene-styrene block copolymer (SIS), urethane rubber, acrylonitrile-butadiene rubber, ethylene-vinyl acetate copolymer, ethylene-ethyl acrylate copolymer, chlorosulfone General synthetic rubbers or elastomers such as fluorinated polyethylene and cyclized rubber, and the like. Among them, styrene-ethylene-butylene-styrene block copolymer (SEBS) is preferable. The glassy resin preferably has a low elongation, a melting point or softening point of 100 ° C. or higher, and a high hardness. For example, a saturated or unsaturated alicyclic hydrocarbon resin or aliphatic hydrocarbon resin, styrene -Acrylic copolymer resins, ketone resins, rosin, rosin derivatives, maleic acid derivatives, carboxyl group-containing resins such as acrylic acid derivatives, and polyolefin resins such as polyethylene and polypropylene, among others, saturated or unsaturated fats A cyclic hydrocarbon resin or an aliphatic hydrocarbon resin is preferred.

  As content of binder resin in a concealing layer, Preferably it is 18-28 mass%, More preferably, 20-25 mass% is mentioned.

  When a glassy resin and a rubbery resin are used in combination as the binder resin for the concealing layer, the weight ratio is not particularly limited, but preferably 0.1% by weight of the rubbery resin relative to 1 part by weight of the glassy resin. The amount is 8 to 1.2 parts by weight, more preferably 0.9 to 1.1 parts by weight.

  The hiding layer contains a white pigment and / or a white extender pigment. The white pigment is not particularly limited as long as it is a white pigment that can ensure the hiding power required for the hiding layer, and examples thereof include titanium oxide and zinc oxide. Among these, titanium oxide is preferable in that the whiteness of the tape can be increased by adding a small amount. These may be used individually by 1 type and may use 2 or more types together.

  Although it does not specifically limit as a particle size of a white pigment, For example, 0.2-0.3 micrometer, Preferably 0.23-0.27 micrometer is mentioned at the point which a concealing layer can have a favorable hiding power.

  The white extender pigment in the present invention is not particularly limited as long as it imparts a good cutting property to the concealing layer. For example, calcium carbonate, magnesium carbonate, barium carbonate, aluminum oxide, silica, celite, Examples include talc and clay. Of these, calcium carbonate and magnesium carbonate are preferred. These may be used individually by 1 type and may use 2 or more types together.

  In the present invention, the total content of the white pigment and the white extender in the masking layer is 70 to 80% by weight, preferably 75 to 80% by weight. If it is less than 70% by weight, the hiding power may be insufficient or the appearance may be impaired. If it exceeds 80% by weight, the amount of the binder resin is reduced and the strength cannot be maintained. There is a risk of tearing.

  The masking layer may contain other components in addition to the binder resin, the white pigment and / or the white extender pigment. Examples of other components include a dispersant and an additive. The dispersant is not particularly limited as long as it can disperse a white pigment such as titanium oxide in an organic solvent, and a known one can be appropriately used. Examples of additives include concealment of typographical errors, etc., and rewriting with a writing instrument using aqueous ink after correction, in order to improve the permeability of the aqueous ink, polyethylene glycol, polypropylene glycol, polyethylene glycol polypropylene glycol A random copolymer or a polyethylene glycol polypropylene glycol block copolymer can be selected. The content of these other components is not particularly limited and may be appropriately designed according to the purpose.

  The concealing layer is a coating in which a white pigment and / or a white extender pigment is mixed with an organic solvent solution, an organic solvent dispersion, or an aqueous dispersion (including an emulsion) of a binder component, and a dispersant, an additive, and the like as necessary. It can be formed by applying and drying a working fluid on a substrate. Application | coating and drying can generally be performed by a well-known method.

The weight of the hiding layer per 1 m ² is 18 to 24 g / m ² (dry weight). If it is less than 18 g / m ² , the concealing power may be insufficient, and if it exceeds 24 g / m ² , the thickness of the entire correction tape will increase, thereby concealing and correcting typographical errors etc. Therefore, when the writing surface including the correction part is concealed and rewritten on the writing surface, the tip of the writing tool gets caught in the step, or the step appears as a shadow when making a copy. There is a risk of malfunction. The weight per m ^{2 of the} masking layer is preferably 19 to 23 g / m ² , more preferably 20 to 23 g / m ² .

(Pressure sensitive adhesive layer)
A pressure-sensitive adhesive layer consists of a conventionally well-known adhesive. Examples of the pressure-sensitive adhesive include acrylic, rubber-based, vinyl ether resin-based, and polyisobutylene-based pressure-sensitive adhesives.

  The pressure sensitive adhesive layer includes carbon black. In the pressure-sensitive transfer correction tape of the present invention, by containing carbon black in the pressure-sensitive adhesive layer, the hiding power can be improved while the thickness of the hiding layer is reduced. Although it does not specifically limit as an average particle diameter of carbon black, 0.1-5.0 micrometers, Preferably 0.5-3.0 micrometers is mentioned. The average particle size is a value obtained by measuring the particle size of 20 or more carbon black particles in a secondary particle state by observation with an electron microscope and averaging them.

The content of carbon black in the pressure sensitive adhesive layer is 0.09 to 0.3% by weight, preferably 0.12 to 0.16% by weight. If the carbon black content is less than 0.09% by weight, the hiding power of the pressure-sensitive transfer correction tape may be insufficient when the weight per m ^{2 of} the hiding layer is as thin as 18 to 24 g / m ^2. If it exceeds 0.3% by weight, the color difference between the side surface of the pressure-sensitive transfer correction tape and the side surface of the pressure-sensitive adhesive layer becomes too large.

  The pressure-sensitive adhesive layer may contain other components as necessary, and examples of the other components include an adhesive strength adjusting agent, a dispersant, an additive, and inorganic / organic fine particles.

  The pressure-sensitive adhesive layer is formed by applying a coating solution prepared by dissolving or dispersing the above-mentioned pressure-sensitive adhesive, carbon black, and, if necessary, other components in an arbitrary solvent, and drying the coating solution. be able to.

The weight per 1 m ^{2 of the} pressure-sensitive adhesive layer is 1.0 to 2.0 g / m ² (dry weight). If it is less than 1.0 g / m ² , the adhesive force of the pressure-sensitive transfer correction tape becomes low, and the tape may be easily peeled off after correction. If it exceeds 2.0 g / m ² , the adhesive strength of the pressure-sensitive adhesive layer becomes excessively strong, and when the correction tape is rolled and stored, the pressure-sensitive adhesive layer and the back surface of the correction tape adhere to each other. Therefore, there is a possibility that a phenomenon called so-called blocking, in which it becomes difficult to be unwound from the wound state during use, or peels off the whole concealment layer and adheres to the back side may occur. The weight per 1 m ^{2 of the} pressure-sensitive adhesive layer is preferably 1.5 to 2.0 g / m ² .

In the pressure-sensitive transfer correction tape of the present invention, the weight ratio of carbon black in the pressure-sensitive adhesive and the like to the white pigment and / or white extender pigment in the hiding layer is preferably white with respect to 1 part by weight of carbon black. The pigment and / or white extender pigment is 2700 to 11000 parts by weight, more preferably 5000 to 8500 parts by weight, and still more preferably 5000 to 7000 parts by weight. When the weight ratio is within the above-mentioned range, when the weight per 1 m ^{2 of} the masking layer is as thin as 18 to 24 g / m ² , the masking surface is excellent in masking power and the side surface of the tape and the pressure sensitive adhesive The difference in color on the side surface of the layer is reduced, and the appearance of the tape is improved.

In pressure-sensitive transfer correction tape of the present invention, the masking layer and the weight ratio per 1 m ² of the pressure-sensitive adhesive layer: A (weight 1 m ² per pressure sensitive adhesive layer weight of 1 m ² per concealment layer) As long as the hiding power becomes good and the difference in color between the side surface of the base material of the tape and the side surface of the pressure-sensitive adhesive layer becomes small, it is not particularly limited, but is 1: 8 to 1:20, preferably 1. : 10 to 1:20.

  In the pressure-sensitive transfer correction tape of the present invention, the color difference ΔE between the surface on which the pressure-sensitive adhesive layer is laminated and the back surface on which the pressure-sensitive adhesive layer is not laminated is 10.0 or less. Is preferred. When the color difference ΔE is 10.0 or less, the difference in color between the front surface and the back surface of the tape is visually reduced, and the appearance of the tape is improved. The color difference ΔE is more preferably 6.0 or less. The color difference ΔE is obtained by placing a pressure-sensitive transfer correction tape on 10 PPC papers, and laminating a surface on which a pressure-sensitive adhesive layer is laminated and a pressure-sensitive adhesive layer on the opposite side. This is a value obtained in the color difference measurement mode of the color difference meter by measuring the hue with the back surface not using a color difference meter such as a color difference meter CR-221 (manufactured by Minolta Camera Co., Ltd.).

  The transmission OD value of the pressure-sensitive transfer correction tape of the present invention is preferably 0.74 or more. When the transmission OD value is 0.74 or more, an excellent hiding power can be exhibited. The transmission OD value is more preferably 0.75 or more. For the transmission OD value, the pressure-sensitive transfer correction tape is transferred to a 100 μm thick PET film, and the transmission OD value of the transferred tape is measured using a spectrocolorimeter such as X-Rite 361T (V) (manufactured by X-Rite). It is a value obtained by measuring.

  The L * value of the pressure-sensitive transfer correction tape of the present invention is preferably 90 or more, more preferably 92 or more. The L * value is determined by placing CIE L * a * b * from the back side where the pressure-sensitive adhesive layer of the pressure-sensitive transfer correction tape is placed on top of 10 sheets of PPC paper. This is a value obtained by measurement using a color difference meter such as a color difference meter CR-221 (manufactured by Minolta Camera Co., Ltd.) under measurement conditions.

  As described above, the pressure-sensitive transfer correction tape of the present invention forms a release layer directly on the base material or on both surfaces of the base material, and forms a concealment layer on one base material surface or on the release layer. It can be manufactured by forming a pressure sensitive adhesive layer on the substrate. The formation method of each layer is as described above in the section of each layer.

  As described above, the pressure-sensitive transfer correction tape of the present invention is thin and excellent in hiding power, and has a small difference in color between the front and back surfaces of the tape and is excellent in appearance.
