Description

  The present invention relates to an antistatic antiglare antireflection coating composition, an antistatic antiglare antireflection film using the same, a polarizing plate and a display device.

  The antiglare film has a function of reducing light reflection using light scattering properties due to surface irregularities. Such an antiglare film is disposed on the surface of various display panels such as a liquid crystal display (LCD), a plasma display (PDP), a cathode ray tube (CRT), an electroluminescent display (EL), etc., and has a contrast due to reflection of external light. It is used for the purpose of preventing the decrease of the display or the visibility of the display due to the image reflection.

  The antiglare film usually comprises an antiglare layer formed by coating a transparent base material with an antiglare coating composition containing translucent fine particles such as silica in micron units or resin beads. The antiglare layer is usually made of translucent fine particles having a large particle diameter so that irregularities can be easily formed on the surface. However, when translucent fine particles having a large particle diameter are used, there is a problem in that the visibility of image information is deteriorated due to whitening phenomenon and bright scintillation on the film surface.

  In addition, in order to prevent dust that tends to adhere to the surface due to the high surface resistance of the antiglare film, an antistatic layer is separately formed on the antiglare layer, or for an excellent image effect, the antiglare film In some cases, an antireflection layer is separately formed. That is, an attempt has been made to secure antistatic properties or antireflection properties in addition to antiglare properties by forming an antistatic layer or an antireflection layer on the antiglare layer. However, since an antistatic layer or an antireflection layer is required in addition to the antiglare layer, at least two steps are required, so that there is a disadvantage that an expensive process cost is required.

  In this regard, Korean Patent No. 963248 describes a multi-layer antistatic antiglare film in which an antiglare layer is formed and then an antistatic layer containing a conductive polymer is formed. Since transparent fine particles are used for the glare layer, the transmittance and contrast are not excellent, the visibility of image information is reduced, and at least two or more steps are required at the time of coating. Take it.

  In order to overcome this, Korean Patent Application Publication No. 2008-0047466 describes an antistatic antiglare film on which an antiglare layer containing translucent fine particles, an antistatic agent and a binder is formed. Therefore, there is a problem that the transparency and the contrast of the image information are deteriorated due to the poor transmittance and contrast.

2 is an enlarged surface photograph (micrograph) of an antistatic antiglare antireflection film produced in Example 1. FIG.

Hereinafter, the present invention will be described in detail.
The antistatic antiglare antireflection coating composition according to the present invention comprises a (meth) acrylate monomer (A), a conductive polymer (B), a quaternary ammonium salt (C), and an alcohol solvent (D). And a ketone solvent (E) and a photoinitiator (F). Details of each component are as follows.

(Meth) acrylate monomer (A)
The (meth) acrylate monomer is included to improve the hardness of the antistatic antiglare antireflection layer.
If the said (meth) acrylate monomer is generally used in the said field | area, it can be used without a restriction | limiting.

  Specific examples of the (meth) acrylate monomer include dipentaerythritol hexa (meth) acrylate, dipentaerythritol penta (meth) acrylate, pentaerythritol tetra (meth) acrylate, ditrimethylolpropane tetra (meth) acrylate, (meth ) Acrylic acid ester, trimethylolpropane tri (meth) acrylate, glycerol tri (meth) acrylate, tris (2-hydroxyethyl) isocyanurate tri (meth) acrylate, ethylene glycol di (meth) acrylate, propylene glycol (meth) acrylate 1,3-butanediol di (meth) acrylate, 1,4-butanediol di (meth) acrylate, 1,6-hexanediol di (meth) acrylate, neopen Diglycol di (meth) acrylate, diethylene glycol di (meth) acrylate, triethylene glycol di (meth) acrylate, dipropylene glycol di (meth) acrylate, bis (2-hydroxyethyl) isocyanurate di (meth) acrylate, hydroxyethyl (Meth) acrylate, hydroxypropyl (meth) acrylate, hydroxybutyl (meth) acrylate, isooctyl (meth) acrylate, isodexyl (meth) acrylate, stearyl (meth) acrylate, tetrahydrofurfuryl (meth) acrylate, phenoxyethyl (meth) At least one selected from the group consisting of acrylate, isoborneol (meth) acrylate and the like can be used.

  Although the usage-amount of the said (meth) acrylate monomer is not restrict | limited, It is preferable that 0.1-50 weight part is contained with respect to 100 weight part of the whole antistatic glare-proof antireflection coating composition. If the content of the (meth) acrylate monomer is less than 0.1 parts by weight based on the above criteria, there is a problem in the surface hardening of the antistatic antiglare antireflection layer, and if it exceeds 50 parts by weight, the coating is caused by an increase in viscosity. And the formation of uniform unevenness may be reduced.

Conductive polymer (B)
The conductive polymer is added to provide antistatic properties, antiglare properties and antireflection properties.
Specific examples of the conductive polymer include poly (3,4-ethylenedioxythiophene), polyacetylene, poly (p-phenylene), polythiophene, polypyrrole, poly (p-phenylene sulfide), and poly (p-phenylene). At least one selected from the group consisting of vinylene), poly (thienylene vinylene), polyaniline and the like can be used, and poly (3,4-ethylenedioxythiophene) excellent in antistatic performance is preferably used. be able to.

  Examples of the poly (3,4-ethylenedioxythiophene) include a commercially available product, Dodencoat UV R-series manufactured by Chukyo Yushi Co., Ltd.

  The content of the conductive polymer is preferably 0.1 to 20 parts by weight, and preferably 0.5 to 10 parts by weight with respect to 100 parts by weight of the entire antistatic antiglare and antireflection coating composition. More preferred. If the content of the conductive polymer is less than 0.1 parts by weight based on the above criteria, the antistatic property is lowered, and if it exceeds 20 parts by weight, the antistatic property is excellent but the transmittance is lowered.

Quaternary ammonium salt (C)
The quaternary ammonium salt serves to promote the floating and aggregation of the conductive polymer on the surface.

  More specifically, the quaternary ammonium salt is dissolved in an alcohol solvent described later. In the process of volatilization of the alcohol solvent and the ketone solvent described later, the quaternary ammonium salt dissolved in the alcohol solvent floats upward. At this time, when the alcohol solvent evaporates, the quaternary ammonium salt becomes conductive. Helps the polymer to float to the top. The conductive polymers floating on the upper surface aggregate with each other or with the quaternary ammonium salt, thereby forming irregularities on the surface of the antistatic antiglare antireflection layer.

  The quaternary ammonium salt is not particularly limited, and a low molecular weight quaternary ammonium salt or a high molecular weight quaternary ammonium salt can be used, and preferably a high molecular weight fourth salt having a number average molecular weight of 4000 or more. A quaternary ammonium salt can be used.

  Examples of the polymer type quaternary ammonium salt include PQ-10 and PQ-50 manufactured by Soken Co., Ltd. as commercially available products.

  The quaternary ammonium salt is preferably contained in an amount of 0.01 to 5 parts by weight, particularly 0.1 to 5 parts by weight, based on 100 parts by weight of the entire antistatic antiglare and antireflection coating composition, and preferably 0.1 to 5 parts by weight. More preferably, it is contained in 1 part by weight. If the content of the quaternary ammonium salt is less than 0.01 parts by weight based on the above criteria, the surface of the antistatic antiglare and antireflection layer is not uneven, so that sufficient antiglare property cannot be obtained and transparent. When the film is manufactured and exceeds 5 parts by weight, there is a disadvantage that the film causes a whitening phenomenon to lower the transmittance.

Alcohol solvent (D)
There is no restriction | limiting in particular in the said alcohol solvent, Any can be used if it is an alcohol solvent which can melt | dissolve a conductive polymer and a quaternary ammonium salt.

  For example, specific examples of the alcohol solvent include methanol, ethanol, isopropyl alcohol, 2-methoxyethanol, 2-ethoxyethanol, propylene glycol monomethyl ether, propylene glycol monomethyl ether acetate, and the like.

  It is preferable that 10-50 weight part of the said alcohol solvent is contained with respect to 100 weight part of the whole antistatic glare-proof antireflection coating composition. If the content of the alcoholic solvent is less than 10 parts by weight based on the above criteria, the compatibility of each component will be reduced and the antistatic antiglare antireflection coating composition will be less stable. Asperities are not easily formed on the surface of the antiglare and antireflection layer, and the adhesion between the antiglare and antireflection layer and the transparent substrate is disadvantageous.

Ketone solvent (E)
The ketone solvent reduces the compatibility of the conductive polymer and the quaternary ammonium salt while being evaporated together with the alcohol solvent during drying, so that the conductive polymer disposed on the surface or between the conductive polymers has high conductivity. It promotes the aggregation of molecules and quaternary ammonium salts to perform the function of forming irregularities on the surface of the antistatic antiglare and antireflection layer.

  The ketone solvent is not particularly limited, but preferably at least one selected from the group consisting of methyl ethyl ketone, methyl butyl ketone, methyl isobutyl ketone, diethyl ketone, and dipropyl ketone can be used.

  The ketone solvent is preferably contained in an amount of 1 to 40 parts by weight with respect to 100 parts by weight of the antistatic antiglare and antireflection coating composition, and particularly 10 to 40 parts by weight from the viewpoint of further improving the antiglare property. It is preferable. If the ketone solvent is less than 1 part by weight based on the above criteria, there is a disadvantage that unevenness is not formed on the surface of the antistatic antiglare antireflection layer during drying. There is a disadvantage that the quaternary ammonium salt is not uniformly dissolved.

  The above-mentioned ketone-based solvent promotes the aggregation of the conductive polymer and the quaternary ammonium salt to form the unevenness on the surface of the antistatic antiglare and antireflection layer more effectively. And a predetermined weight ratio. In particular, the ketone solvent is preferably added so as to have a weight ratio of 1: 9 to 9: 1, preferably 3: 7 to 7: 3 with respect to the alcohol solvent.

  When the ketone solvent is added in an amount of less than 1: 9 by weight with respect to the alcohol solvent, the surface of the surface is uneven because the conductive polymer and the quaternary ammonium salt are less agglomerated. However, when added in excess of 9: 1 weight ratio, the compatibility of the conductive polymer and the quaternary ammonium salt is lowered and the stability is lowered. There is a problem.

Photoinitiator (F)
If the said photoinitiator is used in the said field | area, it can be used without a restriction | limiting. Preferably, the photoinitiator may be at least one selected from the group consisting of hydroxyketones, aminoketones, and hydrogen capture photoinitiators.

  Specific examples of the photoinitiator include 2-methyl-1- [4- (methylthio) phenyl] 2-morpholinepropan-1-one, diphenylketone benzyldimethyl ketal, 2-hydroxy-2-methyl-1-phenyl. -1-one, 4-hydroxycyclophenyl ketone, dimethoxy-2-phenylatetophenone, anthraquinone, fluorene, triphenylamine, carbazole, 3-methylacetophenone, 4-chloroacetophenone, 4,4-dimethoxyacetophenone, 4,4 -At least one selected from the group consisting of diaminobenzophenone, 1-hydroxycyclohexyl phenyl ketone, and benzophenone can be used.

  The photoinitiator is preferably contained in an amount of 0.05 to 5 parts by weight based on 100 parts by weight of the entire antistatic antiglare and antireflection coating composition. If the content of the photoinitiator is less than 0.05 parts by weight based on the above criteria, the curing rate of the antistatic antiglare and antireflection coating composition will be slow. Cracks may occur in the antiglare antireflection layer.

  The antistatic antiglare antireflection coating composition of the present invention comprises, in addition to the above components, an antioxidant, a UV absorber, a light stabilizer, a leveling agent, a surfactant, and an antifouling agent as necessary. It can further contain at least one selected from

  The present invention provides an antistatic antiglare and antireflection film produced using the above-described antistatic and antiglare and antireflection coating composition of the present invention. That is, the antistatic antiglare antireflection film of the present invention is coated with the above-described antistatic antiglare antireflection coating composition according to the present invention on one or both sides of a transparent substrate, and then dried to obtain a highly conductive film. An antistatic antiglare antireflection layer is formed by forming surface irregularities by aggregation of molecules and quaternary ammonium salts and then curing.

  Any film can be used as the transparent substrate as long as it is a transparent film.

After application, the antistatic antiglare antireflection coating composition can be dried by evaporation of volatiles at a temperature of 30 to 150 ° C. for 10 seconds to 1 hour, preferably 30 seconds to 10 minutes.

  While the solvent is volatilized during the drying process, the conductive polymer floats upward due to the interaction with the quaternary ammonium salt. The conductive polymer floating on the top aggregates with each other or with the quaternary ammonium salt. Thereby, unevenness | corrugation is formed in the surface of an antistatic glare-proof antireflection layer.

When the antistatic antiglare and antireflection coating composition is completely dried, it is cured by irradiation with UV light. The irradiation amount of UV light is about 0.01 to 10 J / cm ² , preferably 0.1 to ² J / cm ² .
