ABSTRACT:
Condensation polymers including linear polyester, unsaturated polyester, and polycarbonate types, wherein certain 3H-dibenzo-[f,ij] isoquinoline-2,7-dione colorants are copolymerized (condensed) into the polymer to impart a wide range of colors from yellow to blue thereto. These colorants are fast to ultraviolet and visible light, are thermally stable and nonsublimable at the polymer processing (includes preparation) temperatures, and are nonextractable therefrom, rendering the polymers particularly suitable for use as beverage bottles and food, pharmaceutical and cosmetic containers, as well as in producer colored fibers.
The colorants have the formula ##STR1## wherein: X is --O--, --S-- or --NH--; --X--R.sub.1 --Z in combination is hydrogen or halogen; R.sub.1 is selected from alkyl, aryl, cycloalkyl or the like, and when X is --O-- or --NH--, --R.sub.1 --Z also can be hydrogen; each of R.sub.1, Rhd 2, R.sub.3 and R.sub.4 is hydrogen or an organic substituent; and wherein the molecule carries at least one condensable group.
