Abstract

Abstract Polymeric anthraquinone derived colorants having improved light and alkali fastness properties represented by the formula: ##STR1## wherein R 1 is a member selected from the group consisting of H, OH, a halogen, NH 2 , NO 2 and ##STR2## R 2 and R 3 are members selected from the group consisting of H and OH, R 4 is an alkyl moiety containing at least 1 carbon atom, said polymeric constituent is a member of the group consisting of polyalkylene oxides and copolymers thereof in which the alkylene moiety contains from 2 to about 4 carbon atoms, polyalkylene polyamines in which the alkylene moiety contains from 2 to about 4 carbon atoms, polysaccarides, polyamides, and copolymers of vinyl amine and acrylamide, x is an integer of at least 1, and R 5 is selected from the group consisting of OR 6 or NHR 7 and wherein R 6 is H, an aryl moiety or an alkyl moiety containing from 1 to about 18 carbon atoms and wherein R 7 is an aryl moiety or R 4 - (polymeric constituent-(NH 2 ) x wherein R 4 , polymeric constituent and x are as previously defined.
