Patent ID: 8765659

Claim:
A composition comprising: (a) a microcapsule comprising a shell encapsulating a material having an average C log P of at least about 2.5 and more than 60% by weight of the material has a C log P of at least 3.3, and (b) at least one polymer formed from the polymerisation of: (i) a water soluble ethylenically unsaturated monomer or blend of monomers comprising at least one cationic monomer and at least one non-ionic monomer; wherein the cationic monomer is a compound according to formula (I): wherein: R 1 is chosen from hydrogen or methyl; R 2 is chosen hydrogen, or C 1 -C 4 alkyl; R 3 is chosen C 1 -C 4 alkylene; R 4 , R 5 , and R 6 are each independently chosen from hydrogen, or C 1 -C 4 alkyl; X is chosen from —O—, or —NH—; and Y is chosen from Cl, Br, I, hydrogensulfate, or methosulfate; wherein the non-ionic monomer is a compound of formula (II): wherein: R 7 is chosen from hydrogen or methyl; R 8 is chosen from hydrogen or C 1 -C 4 alkyl; and R 9 and R 10 are each independently chosen from hydrogen or C 1 -C 4 alkyl; at least one cross-linking agent in an amount from 5 ppm to 500 ppm by the weight of component a), and at least one chain transfer agent in the amount of 2000 ppm to 5000 ppm relative to component a); (ii) optionally, a water soluble homopolymer of formula (Ia) Wherein: R 1 is chosen from hydrogen or methyl; R 2 is chosen hydrogen, or C 1 -C 4 alkyl; R 3 is chosen C 1 -C 4 alkylene; R 4 , R 5 , and R 6 are each independently chosen from hydrogen, or C 1 -C 4 alkyl; X is chosen from —O—, or —NH—, preferably —O—; and Y is chosen from Cl, Br, I, hydrogensulfate or methosulfate.
