Abstract
A composition for powder coating which comprises a carboxyl-containing polymer of not lower than 40.degree. C. in softening point prepared by reacting a dicarboxylic acid anhydride with a hydroxyl-containing polymer obtained by saponifying a copolymer from a vinyl ester of a saturated monocarboxylic acid and a copolymerizable vinyl monomer, and a compound having two or more oxazaline rings in the molecule, from which are obtained coating layers with toughness and flexibility useful for coating glass bottles, etc.
