Abstract
Abstract Liquid, water-insoluble colorants and aqueous dispersions of same are provided in which the colorant is represented by the formula R - (oleophilic polymeric constituent) n , Wherein R is an organic dyestuff radical, the oleophilic polymeric constituent is polyalkylene oxides and co-polymers of polyalkylene oxides in which the alkylene moiety of the polymeric constituent contains at least 3 carbon atoms and such polymeric constituent has a molecular weight of at least 500, and n is an integer of from 1 to 6.
