Abstract
Abstract Ultraviolet radiation curable composition comprising a solution of (A) from 5 to about 50 percent by weight of a polyester of terephthalic acid esters and a glycol of from about 60 mole percent to 100 mole percent 1,2-propylene glycol and from 0 to about 40 mole percent ethylene glycol; said polyester having an inherent viscosity of from about 0.05 to about 0.60; and (B) from 95 to 50 percent by weight of an ethylenically unsaturated photopolymerizable compound, Are useful as binders and coating compositions.
