A hydrolyzable resin (A), a first non-hydrolyzable resin (B), a second non-hydrolyzable resin (C) and an antifouling agent (D), the first non-hydrolyzable resin ( The glass transition temperature Tg B [° C.] and the solubility parameter SP B of B) and the glass transition temperature Tg C [° C.] and the solubility parameter SP C of the second non-hydrolyzable resin (C) are obtained by the formula [1] : Tg B −Tg C ≧60, Formula [2]: SP B ≧9.5, Formula [3]: SP C ≧9.5, and Formula [4]: |SP B −SP C |≦1.0 is provided. |
