    摘要: According to the present invention, a coating composition which contains
    (A) a hydrolyzable silyl group-containing acrylic resin,
    (B) an organopolysiloxane that is represented by average unit formula (I), and
    (C) a curing catalyst is able to be produced by a simple process; and
    this coating composition forms a cured coating film that has excellent cracking resistance, coating film hardness, chemical resistance, alkali resistance, heat resistance and weather resistance.
