Abstract

A radiation curable powder coating composition is disclosed, which comprises a blend of (meth)acryloyl group containing polyphenoxy resin, a (meth)acryloyl group containing resin other than the polyphenoxy resin and other than a (meth)acryloyl group containing amorphous polyester and, eventually, a (meth)acryloyl group containing monomer or oligomer. These powders give coatings with improved chemical resistance and flexibility.
