摘要：Disclosed are colorant precursor compounds of the formula wherein R is analkyl group, an aryl group, an arylalkyl group, or an alkylaryl group, and wherein R can bejoined to the phenyl moiety to form a ring, each R′, independently of the others, is ahalogen atom, an alkyl group, an alkoxy group, a nitrile group, a nitro group, an amidegroup, 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 aninteger representing the number of repeat alkylene oxide units, wherein said colorantprecursor has no more than one —OH, —SH, or primary or secondary amino group permolecule.
