CURABLE RESIN COMPOSITION, COATING COMPOSITION, COATING METHOD AND COATED ARTICLE

摘要

The present invention provides a novel curable resin composition insuring good curability even without using an aminoplast curing agent and having an excellent high-solid feature, a sufficient storage stability which consists in a curable resin composition comprising 5 to 80 weight % of a polymer containing free and esterified carboxyl groups and having an acid value of 50 to 300 (mgKOH/g) (1e), 1 to 80 weight % of a polymer containing hydroxyl and epoxy groups and having an epoxy equivalent of 200 to 1000 and a hydroxyl equivalent of 250 to 1500 (2d), and 1 to 50 weight % of an alkoxyl group-containing silicone polymer having an alkoxyl equivalent of 50 to 1500 (3a), 0.1 to 5.0 weight % of a quarternary ammonium salt catalyst (4a) and 0.1 to 5.0 weight % of a monoalkyltin compound (5a).
