Abstract
Polymerizable unsaturated polyester compositions are provided, particularly useful in the manufacture of multilayer laminates, consisting essentially of PA1 (1) a polyester of a polyhydric alcohol and a polycarboxylic acid, at least one of which is ethylenically unsaturated; PA1 (2) a monomer copolymerizable with the unsaturated polyester and having a boiling point below 150.degree. C.; PA1 (3) an additive forming a film on the polyester surface that inhibits volatilization of monomer from the polyester composition; and PA1 (4) a hydrophobic compound soluble at least in part both in the unsaturated polyester and in the film-forming additive that either PA1 (a) has an isoprene unit structure, or PA1 (b) is acyclic and has at least one ester and/or ether bond; and at least two terminal hydrocarbon groups, each with at least one ethylenically unsaturated group.
