13.6 g (0.2 mol) of imidazole and 24.8 g (0.1 mol) of (3-methacryloxypropyl)trimethoxysilane were mixed and reacted at 100° C. for 11 hours. After cooling to room temperature, 100 ml of ethyl acetate was added, and excess imidazole was removed by washing the product three times in 100 ml of deionized water. Molecular sieves were added to the product, and the ethyl acetate solution was dried overnight. Subsequently, the ethyl acetate was distilled off in a rotary evaporator, and the imidazole group-containing silane coupling agent expressed by the formula (4) below was obtained. In the formula, R6, R7, and R8 are H; R9 is CH3; R10 is CH3; o is 3; and p is 3. 12.64 g (0.04 mol) of the imidazole group-containing silane coupling agent thus obtained, 8.64 g (0.06 mol) of 2-phenylimidazole (melting point: 137-147° C.), and 21.0 g (0.1 mol) of trimellitic acid were heated and mixed at 160° C., the reaction was continued for one hour, and the product was cooled to room temperature, yielding an imidazole trimellitate composition that was solid at normal temperature. The solid product thus obtained was ground with a mortar and classified by a sieve with hole openings of 90 microns to yield pulverized Sample No. 2. Evaluation of Adhesion Properties
