< Anti-fingerprint  Composition>

The anti-fingerprint composition (hereinafter referred to as 'fingerprint coating composition') comprising the photocurable fluorine-modified urethane (meth) acrylate resin of the present invention is at least one diisocyanate compound, at least one hydroxyl group-containing fluoroalkyl compound and hydroxyl group At least one or more of a photoinitiator, an inorganic filler, and a dilution solvent for curing with ultraviolet light to a photocurable resin comprising a fluorine-modified urethane (meth) acrylate prepolymer and a (meth) acrylate monomer, which are copolymers of a containing (meth) acrylate. Include your choice. Meanwhile, since the diisocyanate compound, the hydroxyl group-containing fluoroalkyl compound, and the hydroxyl group-containing (meth) acrylate have already been described in detail in the above description of the anti-fingerprint composition, hereinafter, their content ratios and photoinitiators in the anti-fingerprint compositions, Inorganic fillers and diluent solvents are described in detail.

The fluorine-modified urethane (meth) acrylate prepolymer included in the anti-fingerprint composition of the present invention preferably contains 10 to 40 parts by weight based on the total weight of the anti-fingerprint composition. When the fluorine-modified urethane (meth) acrylate prepolymer is contained in less than 10 parts by weight, the fluorine content is low and the fingerprint resistance is low. When the fluorine-modified urethane (meth) acrylate prepolymer is contained in an amount of more than 40 parts by weight, the coating film is too flexible, so that the scratch resistance is not good, and the curability is remarkably high. This is because problems occur that fall.

In addition, it is preferable that the (meth) acrylate monomer included in the to-fingerprint composition of the present invention contain 10 to 30 parts by weight based on the total weight of the to-fingerprint composition. This is because when the (meth) acrylate monomer is included in less than 10 parts by weight, the viscosity of the composition is too high and the hardness of the coating film is lowered. .

On the other hand, the anti-fingerprint coating composition of the present invention is to increase the curing speed by curing with ultraviolet rays, may comprise a photoinitiator for ultraviolet curing. Photoinitiators include 1-hydroxycyclohexylphenyl ketone, 2,2-dimethoxy-2-phenyl-acetophenone, benzaldehyde, anthraquinone, 3-methylacetophenone, 4-chlorobenzophenone, 4,4'-dimethoxy Benzophenone, benzoin propylether, benzoin ethyl ether, 1- (4-isopropyl-phenol) -2-hydroxy-2-methylpropan-1-one, thioxanthone, benzophenone, 2,4,6- Trimethylbenzoyl-diphenylphosphine may be used in any one or a mixture thereof.

In addition, commercially supplied photoinitiators such as Irgacure184, Irgacure651, Irgacure500, Irgacure819, Irgacure907, Irgacure1800 (Shibagai Corporation) and Darocure1116, Darocure1173 (Merck Corporation), Lucirine LR8728 (BASF), Micure HP-8, TPO, CP-4 , BK-6, BP (Miwon Corporation) etc. can be used.

Such a photoinitiator is preferably included in the 2.5 to 7.5 parts by weight based on the total weight of the to-fingerprint composition, when the photoinitiator is contained less than 2.5 parts by weight, the curability by the ultraviolet light is lowered, when included in excess of 7.5 parts by weight of photocuring is too This is because a lot of the adhesion is reduced.

Inventive to fingerprint coating composition may include an inorganic filler which is a filler of inorganic particles in order to improve the scratch resistance of the surface. By using an inorganic filler, scratch resistance can be improved by increasing the coating film hardness on the surface of the coating layer. It is preferable that these inorganic particles are about 10-60 nanometers in average particle diameters.

Inorganic fillers that may be used in the present inventors' fingerprint compositions include silica, titania, alumina, zirconia, tin, zinc, antimony, indium, and the like, and may be used by mixing at least one of them. Among these, it is preferable to use silica, titania, alumina, zirconia. Furthermore, these inorganic particles are preferably modified by a functional group capable of photocuring the particle surface, that is, an acrylate group.

Such an inorganic filler is preferably included in an amount of 5 to 30 parts by weight based on the total weight of the to-fingerprint composition. When the inorganic filler is included in an amount of less than 5 parts by weight, it is difficult to improve scratch resistance, and when it is included in an amount exceeding 30 parts by weight, the curability is included. This is because a problem occurs that the coating film strength of the coating layer is lowered.

The inventors of the present invention may include an organic solvent as a dilution solvent for controlling workability. Organic solvents used as diluents include toluene, xylene, methyl ethyl ketone, acetone, methyl isobutyl ketone, acetone, cyclohexanone, hexaine, heptane, octane, mineral spirit, diethyl ether, isopropyl ether, Tetrahydrofuran, dioxane, ethylene glycol dimethyl ether, ethylene glycol diethyl ether, propylene glycol monomethyl ether, diethylene glycol dimethyl ether, diethylene glycol diethyl ether, propylene glycol monomethyl ether acetate, propylene glycol monoethyl ether acetate , Methanol, ethanol, propanol, butanol, and the like, and these solvents may be used by mixing at least one or more thereof.

Such a dilution solvent is preferably included in 30 to 60 parts by weight based on the total weight of the toluene paint composition, which is less than 30 parts by weight of the diluent solvent, the viscosity of the composition is high, the smoothness is lowered, if it exceeds 60 parts by weight This is because insufficient coating of solvent evaporates during coating.

In the pencil hardness measurement, the crosslinking density was different after curing depending on the content of the fluorine-modified urethane (meth) acrylate prepolymer and the content of the dilution monomer. Could. In the scratch resistance measurement, it can be seen that the scratch resistance is improved when the content of the inorganic filler is large.

Although the technical spirit of the present invention has been described above with reference to the accompanying drawings, it is intended to exemplarily describe the best embodiment of the present invention, but not to limit the present invention. In addition, it is obvious that any person skilled in the art may make various modifications and imitations without departing from the scope of the technical idea of the present invention.
