Abstract:
A process for inhibiting dye transfer from one fabric to another during fabric laundering operations involving colored fabrics, said process comprises contacting fabrics with a laundering solution comprising a water-soluble quaternary polyvinylpyrridinium derivative comprising a quaternary nitrogen, said quaternary polyvinylpyrridinium derivative having the structure ##STR4##wherein a, d, e, and f represent the mole percent of the respective repeating unit, a is 1 to 100, d is 0 to 99, e is 0 to 99; f is 0 to 99; wherein said quaternary polyvinylpyrridinium derivative comprises one or more repeating units selected from the group consisting of an amine oxide (d), an unfunctionalized pyridine group (e) and another monomer (f), R is selected from the group consisting of substituted or unsubstituted C.sub.1 -C.sub.18 alkyl, C.sub.1 -C.sub.18 alkenyl, C.sub.1 -C.sub.18 alkoxy, C.sub.1 -C.sub.18 aryl, and benzyl; R.sub.1, R.sub.2, and R.sub.3, are independently selected from the group consisting of hydrogen, hydroxyl, alkyl having C.sub.1 to C.sub.18, aryl having C.sub.6 to C.sub.18, and alkaryl having C.sub.7 to C.sub.18 ; X.sup.- is independently a halide.
