Abstract

Disclosed is a polycarbonate article coated with a coating composition for glazing, and in particular, the polycarbonate article coated with the coating composition may have an adhesion property with a material made of polycarbonate, thereby protecting the material made of polycarbonate from ultraviolet rays and the like. In addition, among the coating composition, a primer layer from the coating composition may be applied on the material made of polycarbonate may provide and a hard coating layer painted on the primer layer, thereby providing abrasion resistance. The polycarbonate article of the present invention comprises a polycarbonate panel; a primer layer applied on the panel; and a hard coating layer applied on the primer layer.

First claim

an acryl resin compound in an amount of about 25 to 33 parts by weight; an UV stabilizer in an amount of about 1.5 to 3 parts by weight; a leveling additive in an amount of about 0.1 to 0.3 parts by weight; and a first organic solvent in an amount of about 65 to 75 parts by weight, all the parts by weights based on the total weight of the primer layer.

3 . The polycarbonate article of claim 2 , wherein the UV stabilizer is one or more selected from the group consisting of TINUVIN® 400, HOSTAVIN® 3051, HOSTAVIN® 3206, HOSTAVIN® 3330, HOSTAVIN® 3052, HOSTAVIN® 3058, HOSTAVIN® N30, HOSTAVIN® PR-31, HOSTAVIN® TB 01, HOSTAVIN® TB 02, HOSTAVIN® AR08, HOSTAVIN® VSU 3206, HOSTAVIN® 3206, and HOSTAVIN® 3065.

4 . The polycarbonate article of claim 2 , wherein the leveling additive does not affect adhesion property between the primer layer and the hard coating layer, and is a silicon-based leveling additive or a non-silicon-based leveling additive.

5 . The polycarbonate article of claim 2 , wherein the acryl resin compound comprises: an acryl monomer not containing a hydroxy group in an amount of about 17 to 23 parts by weight; an acryl monomer containing a hydroxy group in an amount of about 2 to 5 parts by weight, an initiator in an amount of about 0.1 to 0.5 parts by weight, and a second organic solvent in an amount of about 70 to 80 parts by weight, all the parts by weights based on the total weight of a reaction mixture to produce the acryl resin compound.

6 . The polycarbonate article of claim 5 , wherein the acryl monomer not containing the hydroxy group comprises one or more acryl groups, and comprises one or more selected from the group consisting of a styrene monomer, methyl methacrylate, ethyl methacrylate, butyl methacrylate, methyl acrylate, ethyl acrylate, n-butyl acrylate, an acrylic acid, and a methacrylic acid.

7 . The polycarbonate article of claim 5 , wherein the acryl monomer containing the hydroxy group comprises one or more selected from the group consisting of 2-hydroxyethyl acrylate, 2-hydroethyl methacrylate, and 2-hydroxypropyl acrylate.

8 .
