ABSTRACT:
Disclosed are colorant precursor compounds of the formulawherein R is an alkyl group, an aryl group, an arylalkyl group, or an alkylaryl group, and wherein R can be joined to the phenyl moiety to form a ring, each R′, independently of the others, is a halogen atom, an alkyl group, an alkoxy group, a nitrile group, a nitro group, an amide group, or a sulfonamide group, z is an integer of 0, 1, 2, 3, or 4, n is an integer representing the number of carbon atoms in each repeat alkylene oxide unit, and x is an integer representing the number of repeat alkylene oxide units, wherein said colorant precursor has no more than one —OH, —SH, or primary or secondary amino group per molecule.
