Procedure
As the oil phase component, 10.0 g of trimethylolpropane and xylene diisocyanate adduct (Takenate D-110N, produced by Mitsui Takeda Chemicals, Inc., a 75 mass % ethyl acetate solution), 6.00 g of Light Acrylate DPE-6A (dipentaerythritol hexaacrylate, produced by Kyoeisha Chemical Co., Ltd.) as the polymerizable monomer, and 0.54 g of Pionin A-41C (produced by Takemoto Yushi Co., Ltd.) were dissolved in 16.61 g of ethyl acetate. As the aqueous phase component, 37.5 g of an aqueous 4 mass % PVA-205 (produced by Kuraray Co., Ltd.) solution was weighed. The oil phase component and the aqueous phase component were mixed and emulsified in a homogenizer at 12,000 rpm for 10 minutes. The resulting emulsified product was added to 24.48 g of distilled water and the obtained mixture was stirred at room temperature for 30 minutes and then stirred at 40° C. for 2 hours. The thus-obtained microcapsule solution was diluted with distilled water to a solid content concentration of 15 mass %. The particle diameter of the microcapsule obtained was measured by a particle diameter distribution measuring apparatus “LA-910”, manufactured by Horiba Ltd., and found to be 0.19 μm in terms of the median diameter. Furthermore, the glass transition temperature (Tg) of the microcapsule wall was measured as described above and found to be 95° C.
