Patent ID: 8232236

Claim:
A hard surface cleaner or hard surface treatment comprising a copolymer which copolymer is formed from a) a cationic monomer described by formula (I) wherein: R 1 and R 4 , independently of each other, represent a hydrogen atom or a linear or branched C 1 -C 6 alkyl group; R 2 and R 3 , independently of each other, represent an alkyl, hydroxyalkyl group wherein the alkyl group is a linear or branched C 1 -C 6 chain; n and m are integers between 1 and 3; and X − represents a counterion; b) an anionic monomer selected from the group of monomers consisting of C 3 -C 8 carboxylic, sulfonic, sulfuric, phosphonic or phosphoric acids, anhydrides and salts thereof; c) a substituted (meth)acrylamide described by formula (II) R 1 is hydrogen or methyl, R 2 is hydrogen or C 1 -C 2 alkyl, R 3 and R 4 are independently C 1 -C 8 alkyl; d) optionally, a crosslinker, and e) 0 to 30 wt. % of an additional nonionic monomer; wherein component a) will exceed the molar amount of component b) incorporated into the copolymer by at least 10%, and the cleaner or treatment further contains a nonionic, anionic, cationic, amphoteric or zwitterionic surfactant.
