Procedure

Subsequently, a solution mixture of butyl acrylate (150 g), tetraethoxysilane (30 g), phenyltrimethoxysilane (145 g) and 3-methacryloxypropyltrimethoxysilane (1.3 g) and a solution mixture of N-isopropylacrylamide (165 g), acrylic acid (3 g), a reactive emulsifier (trade name “ADEKA REASOAP SR-1025”, manufactured by ADEKA Corporation, an aqueous solution containing 25 mass % solid content) (13 g), a 2 mass % aqueous ammonium persulfate solution (40 g) and ion-exchanged water (1900 g) were simultaneously added dropwise over about two hours while keeping the temperature of the reaction vessel at 80° C. Furthermore, stirring was continued for about two hours while keeping the temperature of the reaction vessel at 80° C. Thereafter, the temperature of the reaction vessel was cooled to room temperature and filtration was performed by a 100 mesh wire netting. The solid content concentration was controlled to be 10.0 mass % with ion-exchanged water to obtain a water dispersion of the polymer emulsion particle (HB-7) having a number average particle size of 70 nm. The content of an aqueous-phase component was 18 mass %.
