CURABLE COMPOSITION FOR TOP COATING AND ARTICLES COATED USING THE SAME

摘要

A curable composition for top coating which possesses not only excellent acid and scratch resistances, but also well-balanced coating properties in respect of weather resistance, appearance, recoat adhesion, and thermosetting property and excellent stain resistance. The composition comprises (A) 100 parts by weight of an epoxy resin, (B) 0.001 to 100 parts by weight of a carboxylated compound or resin, and (C) 1.0 to 100 parts by weight of a silicon compound represented by the general formula (I) (R<1>O)4-aSiR<2>a and/or a partial hydrolyzate thereof, wherein R<1> represents a hydrogen atom or an alkyl group having 1 to 10 carbon atoms, an aryl group having 6 to 10 carbon atoms, or an aralkyl group having 7 to 10 carbon atoms; R<2> represents an alkyl group having 1 to 10 carbon atoms, an aryl group having 6 to 10 carbon atoms, an aralkyl group having 7 to 10 carbon atoms, or an alkoxy group having 1 to 10 carbon atoms; and a is an integer of 0 to 2.
