Abstract
A photopolymerizable coating composition comprising: PA1 (A) 100 parts by weight of a vehicle consisting essentially of a urethaneacrylate oligomer; PA1 (B) from 0.1 to 5 parts by weight of an acylphosphine oxide compound as a photoinitiator; PA1 (C) from 1 to 100 parts by weight of a color pigment; and PA1 (D) from 20 to 300 parts by weight of a transparent glass powder having an average particle size of not larger than 100 .mu.m and an index of refraction which does not differ more than 0.3 from the index of refraction of the composition excluding the color pigment.
