PURPOSE: Provided are a paint composition showing excellent flexibility, hardness, ultraviolet curing, abrasion resistance, weatherability, and chemical resistance when used in application requiring for flexibility such as plastic bottle, telephone, sheet, film, and so on, and a molded plastic article coated with the composition. CONSTITUTION: The photocurable paint composition comprises 10-70 parts by weight of urethane acrylate of formula 1, 10-30 parts by weight of specifically modified polyfunctional monomer, 10-50 parts by weight of reactive monomer, 0.1-20 parts by weight of photosensitizer, 10 parts by weight or less of leveling agent, and small amount of additives. In the formula 1, R1 represents hydrogen atom or methyl group, R2 represents (CH2)n or formula a and b(wherein n is an integer of 2-6, R4, R5 and R6, which are same or different, represent a linear alkyl group, provided that at least one of R4, R5 and R6 is methyl group, R7 represents an aliphatic, cycloaliphatic or aromatic compound), X represents formula c(wherein b is an integer of 5-20, c is an integer of 2-5, Y is hydrogen atom or methyl group). |
