Abstract
The present invention provides a fabric washing composition and aqueous treatment solution for inhibiting dye from transferring from one fabric to the same or different fabric in a fabric washing process. The fabric washing composition and aqueous treatment solution contain at least one dye deposition inhibiting polymer. The dye deposition inhibiting polymer contains, as polymerized units, from 5 to 100 weight percent of at least one vinyl amide monomer and from 0 to 95 weight percent of one or more vinyl ester monomers. The present invention also provides a method for inhibiting the deposition of dye by adding at least one of dye deposition inhibiting polymer useful in the present invention to a fabric washing process where dye may be released.
