Claims10
An aqueous curable composition consisting essentially of:
- (a) at least one polycarboxy homopolymer or polycarboxy copolymer comprising at least two carboxylic acid groups, anhydride groups, or salts thereof;
- and
- (b) at least one polyol having two hydroxyl groups, selected from the group consisting of an alkoxylated alkylamine and an alkoxylated alkylamide, wherein the aqueous composition does not comprise an emulsion polymer.
A method for treating fibrous, non-woven or composite substrates comprising:
- forming a curable aqueous composition by admixing with water or a mixture of water and one or more water-miscible solvent (a) at least one polycarboxy homopolymer or copolymer comprising at least two carboxylic acid groups, anhydride groups, or salts thereof;
- and
- (b) at least one polyol having two hydroxyl groups, selected from the group consisting of an alkoxylated alkylamine, and an alkoxylated alkylamide wherein the aqueous composition does not comprise an emulsion polymer and component (a) is in the form of a solution in an aqueous medium;
- contacting a substrate with said curable aqueous composition or, alternatively, applying said curable aqueous composition to said substrate;
- and
- heating said curable aqueous composition at a temperature of from 100° C. to 400° C.
