Patent ID: 11472967

Abstract:
Provided is an antifouling coating composition containing a hydrolyzable resin (A), a first non-hydrolyzable resin (B), a second non-hydrolyzable resin (C), and an antifouling agent (D), in which a glass transition temperature TgB [° C.] and a solubility parameter SPB of the first non-hydrolyzable resin (B), and a glass transition temperature TgC [° C.] and a solubility parameter SPC of the second non-hydrolyzable resin (C) satisfy an expression [1]:TgB−TgC≥60, an expression [2]:SPB ≥9.5, an expression [3]:SPC≥9.5, and an expression [4]:SPB−SPC|≤1.0.
