COLORED UNSATURATED POLYESTER MATERIAL CONTAINING COPOLYMERIZED METHINE DYES, AND PRODUCTS THEREFROM Abstract Colored unsaturated polyesters having copolymerized therein certain methine dyes which condense during polymerization into the polyester chain. The dye moieties are thermally stable at the polymer processing temperatures and are colorfast and nonextractable from the polymer, which makes these colored unsaturated polyesters particularly suitable for crosslinking in the molding of bathroom fixtures (sinks, showers, tubs), boats, certain automotive applications, and the like. The addition of dyes to the polyester in this manner gives less chance of colorant nonuniformity as is the case where the colorant is dispersed in the blend of unsaturated polyester, crosslinking agent, catalyst, etc., prior to casting, molding, and curing operations.
