ABSTRACT OF THE DISCLOSURE A family of non-crystallizing acrylated polyester resins are described in which the polyesters are formed by reacting a mixture of 100 mol percent dicarboxylic acids of which 50 to 100 mol percent is isophthalic acid; 0 to 25 mol percent is terephthalic acid; and 0 to 50 mol percent is one or more dicarboxylic acids other than isophthalic or terephthalic; with an excess of two or more primary glycols, the maximum mol percent of any one glycol being dependent on the amount of isophthalic acid with the upper limit being established according to the following equation MMG = 149 - 1.08 MlA wherein MMG represents the maximum mol percent of any one glycol and MlA represents mol percent of isophthalic acid in total acids.
