Laminating resins having low organic emissions (I)
First Claim
Patent Images
1. A laminating resin composition characterized by low volatile emissions comprising (A) a base unsaturated polyester resin comprising glycols, unsaturated polycarboxylic acids or derivatives thereof, and, optionally, saturated dicarboxylic acids and (B) alkoxylated bisphenol-A diacrylate or dimethacrylate having at least two alkoxy groups, in a weight ratio of (A) to (B) of 2:
- 1 to 0.5;
1, and (C) about 20% to about 60% by weight, based on the total of components (A) and (B) of a compound of the formula ##STR3## where on H connected to the ring is substituted by CH3, and wherein said composition emits no more than 20.0 g/m2 of volatile emissions as measured by Section 1162 of the Regulations of the South Coast (California) Air Quality District.

Abstract
A laminating resin is made from (1) an unsaturated polyester resin, (2) a diacrylate or dimethacrylate of alkoxylated bisphenol-A, and (3) vinyl toluene. The resin requires no styrene to achieve excellent laminating resin properties, and is significantly inhibited from emitting volatiles during use.
