    摘要: A curable resin composition comprising a cured matrix-forming component and an ultraviolet absorber, characterized in that said ultraviolet absorber comprises a benzophenone derivative represented by the formula: ##STR1## where each of X and X' is a hydrogen atom or a hydroxyl group, provided that at least one of X and X' is a hydroxyl group, each of Y and Y' is a hydrogen, a hydroxyl group, --OROH or --OR', provided that at least one of Y and Y' is --OROH, where R is an alkylene group and R' is a monovalent organic group, and said cured matrix-forming component is reactive with a hydroxyl group.

    摘要: An anticorrosive coating process comprises:(i) a step of forming a primer coating layer by applying on a substrate an oil-type anticorrosive coating or an alkyd resin-type anticorrosive coating as a primer coating, followed by air-drying,(ii) a step of forming a binder coating layer by applying on the primer coating layer a phenol-modified alkyd resin-type coating containing a flaky pigment, followed by air-drying, and(iii) a step of forming a top coating layer by applying on the binder layer a top coating comprising (a) a fluorine-containing copolymer composed of from 40 to 60 molar % of a fluoroolefin, from 5 to 45 molar % of cyclohexylvinyl ether, from 5 to 45 molar % of an alkylvinyl ether, from 3 to 15 molar % of a hydroxyalkylvinyl ether and from 0 to 30 molar % of other comonomer and (b) a polyisocyanate, followed by air-drying.
