Patent ID: 8728618

Claim:
A coating composition, comprising: a coating film forming component that consists of a urethane(meth)acrylate and a photopolymerization initiator, wherein the urethane(meth)acrylate is a reaction product of hydrogenated xylene diisocyanate and/or hydrogenated diphenylmethane diisocyanate, polyol selected from the group consisting of polyether polyols, polyvalent alcohols, polyester polyols, 1,4-cyclohexanediol, and 2,2′-bis(4-hydroxycyclohexyl) propane, and (meth)acrylate having a hydroxyl group, wherein the polyvalent alcohols are selected from the group consisting of ethylene glycol, propylene glycol, 1,6-hexanediol, neopentylglycol, trimethylolpropane, and pentaerythritol, and the average molecular weight between crosslinking points of the urethane(meth)acrylate is 150 to 1500, or the average molecular weight between crosslinking points of the urethane(meth)acrylate and active energy beam-curable component is 150 to 1500 when the active energy beam-curable component is included in the coating composition.
