Abstract
The invention concerns a coating powder composition comprising (A) a carboxyl group containing polyester resin having a number average molecular weight of 1,000.about.20,000, an acid value of 10.about.100, a glass transition temperature of 35.degree.-120.degree. C. and an SP value of 9.8.about.11.5, and (B) glycidyl trimellitate, wherein the equivalent weight ratio of carboxyl the groups of said (A) to the glycidyl groups of said (B) is 1:2 to 2:1. The coating powder composition is specifically suitable for a high-temperature-short time baking and capable of resulting in a coating having excellent film properties including bending and processability and which coating is highly-crosslinked.
