ANTISTATIC AND TRANSPARENT HARD COATING COMPOSITION AND METHOD FOR COATING SURFACE OF PLASTIC BY USING THE SAME

摘要

PURPOSE: An antistatic and transparent hard coating composition is provided, which has excellent physical properties such as scratch-resistance, wear-resistance and the like, also has excellent transparency and provides beautiful external appearance when being coated on transparent plastic. And a method for coating the surface of plastic by using the same is also provided. CONSTITUTION: The antistatic transparent hard coating composition comprises: (i) 6-20 wt.% of a polythiophene conductive polymer aqueous solution; (ii) 10-50 wt.% of an ultraviolet rays hardened type acrylic monomer; (iii) 42-81 wt.% of an organic solvent; (iv) 2-7 wt.% of a photo-initiator; and (iv) 0.05-1.0 wt.% of an ultraviolet rays stabilizer and absorbing agent. The method for coating the surface of plastic comprises steps of: (i) after coating a plastic base plate with the antistatic and transparent hard coating composition, drying it at a temperature of 30-60 deg.C for 1-10 minutes to completely remove the organic solvent from the mixture composition; and (ii) irradiating ultraviolet rays having a light amount of 200-600 millijoule per square centimeters to the plastic base plate of the step (i) to form a coating film.
