    摘要: A powder coating composition comprising as essential components: (A) polyester resin having at least two hydroxyl groups in a molecule, and (B) polyvalent organic cyanate having at least two cyanate groups in a molecule of the following formula and/or its prepolymer;
    wherein A is a C 1-6 hydrocarbon group, and the residues A may be different from each other; X is a single bond, a C 1-20 hydrocarbon group, carbonyl group, sulfone group, divalent sulfur atom or oxygen atom; i is an integer of 0 to 3, which may be different from each other; and n is 0 or 1. The powder coating compound gives improved environmental sanitation in curing and high surface smoothness and high corrosion resistance of the coated product.
