ABSTRACT:
An addition polymer of a water insoluble soft monomer, a water soluble anionic monomer and, optionally, a water soluble nonionic monomer and water insoluble hard monomer is neutralized to at least about 75%, and formed into a sheet. A laundry care additive, as a bleach, may be stored between a pair of opposed heat sealed sheets to provide a laundry care product adapted to be introduced into a laundry wash.
