  • Method of forming a two-layer coat
    Patent number: 6676997
    Abstract: A method of forming a two-layer coat, which comprises the steps of: applying (1) a coating composition onto a thermoplastic resin base and drying the coating to form a colored layer, the coating composition (1) comprising: (A) an acrylic resin obtained by copolymerization of a monomer mixture comprising n-butyl (meth)acrylate and methyl (meth)acrylate, each in an amount of at least 30 wt. %; (B) a colorant; and (C) an organic solvent; applying (2) an energy beam curable overcoat composition onto the colored layer, the overcoat composition (2) comprising: (D) a compound having at least three (meth)acryloyl groups and having a molecular weight of 250 to 1,800; and (E) an acrylic resin obtained by copolymerization of a monomer mixture comprising at least 20 wt. % of methyl (meth)acrylate, the compound (D) amounting to at least 50 wt. % of overcoat film-forming components; and curing the applied overcoat composition by energy beam irradiation.
