Abstract
Abstract Novel radiation curable compositions incorporating a mixture of: 1. Unsaturated polyester prepared from polyhydric alcohol, unsaturated dicarboxylic acid and with or without saturated dicarboxylic acid, or unsaturated ether type polyester prepared for polyglycidyl ether and unsaturated monocarboxylic acid with 2. Saturated monomer of lactone or lactam type. The above compositions are cured with or without radiation sensitive additive and are useful in coating or printing ink applications.
