Poly(oxyalkylene) modified phthalocyanine colorants

Abstract

A colorant for natural or synthetic resinous or polymeric materials, having the formula A--[SO.sub.2 --N(R.sub.2)--Y].sub.1-4 ; wherein: R.sub.2 is selected for example from hydrogen, methyl, cyclohexyl, phenyl or Y; A is a nonionic metallophthalocyanine chromophore which can be substituted for example with halogen, alkyl, alkoxy, alkylthio, or aryloxy; Y is a poly(oxyalkylene) moiety containing at least three monomeric units or mixtures thereof of the formula (--RO--) wherein each R is straight or branched alkylene of 2-4 carbons or mixtures thereof, up to about 20 mole percent of said monomeric units may be connected by one or more linking groups such as alkyleneoxy, --NH--, or --NHCONH--, and wherein Y can be terminated by hydrogen, or by at branch subsituents, containing 1-3 groups or moieties selected from alkyl, cycloalkyl, acyl, or aryl; wherein any of the above recited hydrocarbon groups, moieties or substituents may themselves be substituted with up to four substituents selected, for example, from alkyl, halogen, mercapto, alkoxycarbonyl, hydroxy, alkoxy, or the like; and wherein each aliphatic hydrocarbon portion or moiety of the groups, moieties or substituents recited above contains from 1-20 carbons.
