TITLE: COLORED UNSATURATED POLYESTER MATERIAL CONTAINING COPOLYMERIZED METHINE
DYES, AND PRODUCTS THEREFROM
European Patent EP0235198
 B1

ABSTRACT:
Abstract not available for EP0235198
Abstract of corresponding document: WO8701121
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.
