ABSTRACT:
Polymeric anthraquinone derived colorants having improved light and alkali fastness properties represented by the formula: ##STR1## wherein R.sub.1 is a member selected from the group consisting of H, OH, a halogen, NH.sub.2, NO.sub.2 and ##STR2## R.sub.2 and R.sub.3 are members selected from the group consisting of H and OH, R.sub.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.sub.5 is selected from the group consisting of OR.sub.6 or NHR.sub.7 and wherein R.sub.6 is H, an aryl moiety or an alkyl moiety containing from 1 to about 18 carbon atoms and wherein R.sub.7 is an aryl moiety or R.sub.4 - (polymeric constituent-(NH.sub.2).sub.x wherein R.sub.4, polymeric constituent and x are as previously defined.
