Abstract
The invention concerns a bleach resist composition comprising: (a) a component selected from the group consisting of (1) an anionically modified phenol formaldehyde polymer comprising a phenol moiety and a formaldehyde moiety, (2) a naphthalene condensate, (3) a lignin sulfonate, (4) a phenol sulfonate derivative, a mixture thereof and (5) a (meth)acrylic polymer comprising residues of acrylic or methacrylic acid; and (b) a polyester. Further provided are methods of imparting bleach resistance to a substrate with the compositions of the invention.
Claims17
A method of treating a substrate for bleach resistance comprising applying to the substrate a solution comprising
- (a) a component selected from the group consisting of
- (1) an anionically modified phenol formaldehyde polymer comprising a phenol moiety and a formaldehyde moiety,
- (2) a naphthalene condensate,
- (3) a lignin sulfonate, and
- (4) a (meth)acrylic polymer comprising residues of acrylic or methacrylic acid;
- (b) a polyester;
- and
- (c) water
- wherein the solution applied to the substrate is at a pH of between 1 and 3.5.
