Claim 0:
1. A composition comprising:
a graft copolymer comprising
(a) a polyalkylene oxide which as a number average molecular weight of from about 1000 to about 20,000 Daltons and is based on ethylene oxide, propylene oxide, or butylene oxide,
(b)N-vinylpyrrolidone, and
(c) vinyl ester derived from a saturated monocarboxylic acid containing from 1 to 6 carbon atoms and/or a methyl or ethyl ester of acrylic or methacrylic acid,
wherein the weight ratio (a):(b) is from about 1:0.1 to about 1:1,
wherein the amount, by weight, of (a) is greater than the amount of (c),

an amphiphilic copolymer that is free of vinyl pyrrolidone, the amphiphilic copolymer comprising vinyl acetate grafted to a polyalkylene oxide base; and
a treatment adjunct;
wherein the composition is a fabric care composition and the ratio by weight of the graft copolymer to the amphiphilic polymer is from about 1:10 to about 10:1.
