Procedure

First, 4.24 g of an adduct (trade name: Colonate L, a substance containing 25% by mass of ethyl acetate, produced by Nippon Polyurethane Industry Co., Ltd.) in which tolylenediisocyanate and trimethylolpropane are added in a ratio of 3:1 (molar ratio) as a material for forming micro-capsule walls, 1.12 g of trimethylolpropane triacrylate (produced by Kyoeisha Chemical Co., Ltd.), and 0.93 g of a near-infrared absorbing dye (“KayasorbIR-820B” produced by Nippon Kayaku Co., Ltd.) were dissolved uniformly in 21.7 g of glycidyl methacrylate to prepare an oil component.
