The materials used in various display and industry groups are dazzled by the interference of reflected light when a light source such as a fluorescent lamp or a sunlight is projected on the surface, and visibility is lowered to cause eye fatigue and headache. In order to solve this problem, an anti-glare surface treatment is performed in which the outline of the image reflected on the surface is blurred to reduce the projection of the reflection image.

The anti-glare surface treatment technology is a surface treatment technique for inducing scattering of external light by imparting a concavo-convex shape to the surface of the substrate so as to have a roughness of several tens to several hundreds of nanometers. By forming a rugged surface on the outermost edge of the substrate to reduce direct reflection and diffuse reflection at various angles, the intensity of the reflected light entering the observer's field of view at a certain angle can be reduced and the effect can be obtained. Conventional anti-glare films are provided with surface irregularities by using a chemical etching method, a transfer method using a mold, a particle dispersion method in a resin layer, or the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

Throughout the specification, when an element is referred to as "comprising ", it means that it can include other elements as well, without excluding other elements unless specifically stated otherwise.

An anti-glare coating composition according to the present invention comprises a polysilazane, a curable catalyst and a solvent. The polysilazane according to the present invention may include an inorganic polysilazane or a mixture of an organic polysilazane and an inorganic polysilazane. Specifically, the polysilazane may be represented by the following formula (1).

[Chemical Formula 1]

In Formula 1, R ₁ , R _2, and R ₃ are each independently hydrogen; heavy hydrogen; halogen; An amine group; An epoxy group; Cyclohexyl epoxy group; (Meth) acrylic group; A diazo group; Isocyanate group; A nitrile group; A nitro group; A phenyl group; A halogen atom, an amino group, an epoxy group, a (meth) acrylic group, a silyl group, Or an alkoxy group having from 1 to 40 carbon atoms or a cycloalkyl group having from 3 to 40 carbon atoms or a heterocycloalkyl group having from 3 to 40 carbon atoms or an aryl group having from 6 to 40 carbon atoms or a heteroaryl group having from 3 to 40 carbon atoms or an aralkyl group having from 3 to 40 carbon atoms, An aryloxy group having 3 to 40 carbon atoms or an arylcyclic group having 3 to 40 carbon atoms, and x is an integer of 2 to 1000.

Specifically, when the polysilazane is an inorganic polysilazane, all of R ₁ , R _2, and R ₃ do not have a group containing carbon, and specifically, an inorganic polysilazane in which R ₁ , R _2, and R ₃ are both hydrogen Can be used. When the polysilazane is a mixture of an organic polysilazane and an inorganic polysilazane, at least one of R ₁ , R ₂ and R ₃ is an alkyl group, an alkenyl group, a cycloalkyl group, an aryl group, a group directly bonded to silicon An alkylsilyl group, an alkylamino group or an alkoxy group.

The polysilazane does not correspond to a particulate phase in the anti-glare coating composition, specifically, the polysilazane does not correspond to a particulate matter having a size of 1 nm to 1000 μm. The particles refer to very small particles having a particle size of several nanometers to several nanometers to a few nanometers, and generally have inorganic, organic, and organic hybrids. These particles have been used essentially to achieve anti-glare effects in anti-glare coating compositions, and silica, hollow silica, PMMA, and the like have been used in conventional anti-glare coating compositions. However, in the case of containing particles, there is a problem that the uniformity of the coating is lowered due to the agglomeration of the particles due to the attraction of the particles themselves. To solve this problem, the dispersing agent and leveling agent were added to the coating composition, Respectively.

Therefore, the anti-glare coating composition does not contain particulate matter and uniformity can be improved by forming a uniform morphology (hereinafter referred to as a projection) by adding a curable catalyst to the polysilazane. When the polysilazane is used, it is possible to form uniform irregularities at the time of curing and variously control the size of the morphology formed on the coating layer. The polysilazane may have a weight average molecular weight of 5,000 to 200,000, and more specifically 6,000 to 30,000.

The anti-glare coating composition according to the present invention comprises a curable catalyst. The curable catalyst may be a thermosetting catalyst, a photo-curable catalyst, or the like. Specifically, a curable catalyst containing an amine may be used. More specifically, a thermosetting catalyst containing an amine may be used.

The curable catalyst serves to rapidly convert the polysilazane to a silicate. Even when the anti-glare coating composition according to the present invention does not contain particles, a morphology is formed in a semi-cured state when the anti-glare coating layer is formed by spraying The anti-glare effect can be realized. The following formula (2) is a process in which the polysilazane is cured with a silicate by the curable catalyst.

(2)

(2), the curing of the polysilazane is carried out in such a manner that water (H ₂ O) and oxygen (O ₂₎ in the air are converted into three hydrogen (H) and one nitrogen Lt; / RTI > Thereafter, ammonia (NH ₃ ) and hydrogen (H _{2), which} are byproducts of the reaction _, are heat-treated and vaporized into air to obtain a silicate structure of SiO ₄ . In general, the curing of the polysilazane is carried out at a high temperature (300 ° C or higher). However, the present invention is not limited to the case where the amine catalyst (NH ₂ ) as a thermosetting catalyst is added so that the polysilazane can react with ammonia (NH ₃ ) (H ₂ ) can be rapidly produced and vaporized to obtain a silicate structure of SiO ₄ .

Further, the curable catalyst improves the curing rate in forming the coating layer, and can be rapidly cured and cured at a low temperature (50 to 120 캜), contributing to the formation of an anti-glare coating layer usefully in a short time even in heat- do.

The curable catalyst is selected from the group consisting of 1-methylpiperazine, 1-methylpiperidine, 4,4'-trimethylene dipiperidine, 4,4'-trimethylene bis (1-methylpiperidine), diazabicyclo [ 2,2,2] octane, cis-2,6-dimethylpiperazine, 4- (4-methylpiperidine) pyridine, pyridine, dipyridine,? -Picoline,? -Picoline, Pyridine, pyridine, pyridazine, 4,4'-trimethylenedipyridine, 2- (methylamino) pyridine, pyrazine, quinoline, quinoxaline, triazine, pyrrole, , N-heterocyclic compounds such as triazole, tetrazole and 1-methylpyrrolidine; Examples of the amine include methylamine, dimethylamine, trimethylamine, ethylamine, diethylamine, triethylamine, propylamine, dipropylamine, tripropylamine, butylamine, dibutylamine, tributylamine, pentylamine, dipentylamine, tri Amines such as pentylamine, hexylamine, dihexylamine, trihexylamine, heptylamine, diheptylamine, octylamine, dioctylamine, trioctylamine, phenylamine, diphenylamine and triphenylamine, Diazabicyclo [5,4,0] 7- undecene), DBN (1,5-diazabicyclo [4,3,0] 5-nonene), 1,5,9-triazacyclododecane , 1,4,7-triazacyclononane, and the like, and two or more of them may be used in combination.

The curable catalyst may be used in an amount of 0.05 to 10% by weight based on the weight of the polysilazane pure substance, and the anti-glare coating layer having an excellent uniformity can be formed using the weight ratio. When the content of the curable catalyst is less than 0.05% by weight based on the pure polysilazane, the curing catalyst does not play a role and the curing catalyst does not act at room temperature. When the content exceeds 10% by weight, The stability becomes poor.

The solvent contained in the anti-glare coating composition of the present invention is not particularly limited as long as it can dissolve the polysilazane and the solvent, and examples thereof include petroleum solvents such as mineral spirits, paraffin solvents, aromatic solvents, alicyclic solvents And the like. More specifically, the solvent may be octane, 2,2,3-trimethylpentane, nonane, 2,2,5-trimethylhexane, decane, n-undecane, and may be xylene, cumene, mesitylene, naphthalene, tetrahydronaphthalene, Butylbenzene, p-cymene, diethylbenzene, tetramethylbenzene, pentylbenzene, and may be methylcyclohexane, ethylcyclohexane, p-menthane, a-pinene, dipentene, decalin or dibutyl ether. These solvents may be used alone or as a mixture of two or more thereof.

The anti-glare coating composition according to the present invention may further comprise additives as required. The additive may be any of known additives contained in the coating composition. Specifically, the antifoaming agent and leveling agent may be used as known additives to improve bubble control and coatability. The content of the additive can be adjusted arbitrarily within a range that does not change the physical properties of the coating composition. Specifically, 0.001 wt% to 5 wt% of the additive can be independently used for each component of the additive to improve the physical properties of the coating composition ,

The anti-glare substrate according to the present invention includes a substrate and an anti-glare coating layer containing a silicate on one side or the other side of the substrate.

Referring to FIG. 1, an anti-glare substrate 100 according to an embodiment of the present invention may include a substrate 101 and an anti-glare coating layer 102 formed on the substrate. The substrate 101 is not particularly limited, and concrete examples thereof may be plastic, glass, metal, ceramic, or fiber.

The anti-glare coating layer 102 is formed on the substrate 101 to provide an anti-glare effect. The anti-glare coating layer 102 can vary the size of the morphology according to the content of the polysilazane and the curable catalyst, the number of times of spraying of the coating liquid, the injection amount and the spraying height, and the surface roughness and gloss can be freely adjusted. Specifically, the anti-glare coating layer 102 may form a morphology of 10 to 10 탆 in height (may be referred to as a diameter if necessary), and may have a surface roughness (RA) of 10 to 25 nm and a surface roughness % Glossiness can be realized. In addition, the anti-glare coating layer 102 according to the present invention can prevent the adhesion of the anti-glare coating layer 102 to the substrate, decrease in uniformity due to gravitational entanglement, deterioration of abrasion resistance due to dropping of the particles, And abrasion resistance.

Referring to FIG. 2, the anti-glare substrate 100 may further include a hard coating layer 103 between the substrate 101 and the anti-glare coating layer 102. In particular, when the surface hardness of the substrate is low, such as when the substrate 101 is made of plastic, the hard coat layer 103 can be formed to improve the hardness of the substrate. In this case, the hard coat layer 103 may be formed on the substrate 101 by a known method. For example, a known hard coat composition may be coated on the substrate 101 and cured to form the hard coat layer 103 . The thickness of the hard coat layer 103 may be arbitrarily adjusted, and may be 1 탆 to 100 탆. Thereafter, the anti-glare coating layer 102 may be formed by spray-coating and curing the anti-glare coating composition of the present invention on the hard coat layer 103. The thickness of the antiglare coating layer 102 may be arbitrarily adjusted, and may be 10 nm to 10 μm.

The method for manufacturing an anti-glare substrate according to the present invention includes the steps of providing a substrate and spray-coating the anti-glare coating composition of the present invention at room temperature on the substrate to form an anti-glare layer. The antiglare coating composition may be sprayed at room temperature by spraying and then cured to form an anti-glare coating layer. Specifically, the anti-glare coating composition can form a semi-cured coating layer on the surface of the substrate by depositing semi-hardened particles on the surface of the substrate, The coated layer may be cured to finally form an antiglare coating layer. The curing may be a known curing method and may be thermosetting or photo-curing, and more specifically, 50 ° C to 120 ° C hot air drying. Thus, it is possible to prevent a change in the characteristics of the coating layer due to distortion of the substrate due to heat or denaturation of the component during the curing process.
