Each of the G radicals is independently selected from the group consisting of: (a), (b) and (c); A is an arylene or heteroarylene, A1 is an aryl or heteroaryl, and B is a bridge member. R1 and R2 are independently selected from the group consisting of hydrogen and R4. R4 is independently selected from the group consisting of alkyl, cycloalkyl, aryl, alkoxy, amino, substituted alkyl, substituted cycloalkyl, substituted aryl, substituted alkoxy and substituted amino. Χiθ is a charge balancing mono- or multi-valent counterion and i is an integer from 1 to 10. Methods of making the leuco polymer and methods of treating textiles with such laundry care compositions.
