Abstract
A method of obtaining a leuco polymer, the method comprising the step of reacting a compound with a polymer to form the leuco polymer. The compound includes at least one leuco moiety and at least one electrophilic group. The polymer is comprised of co-monomers of an aryl dicarboxylate, an oxyalkyleneoxy and an oxypolyalkyleneoxy and the polymer comprises at least one moiety selected from the group consisting of hydroxy, sulfhydryl, primary amine and secondary amine. Laundry care compositions comprising the leuco polymer and methods of treating textiles with such laundry care compositions.
