Patent ID: 7651693

Claim:
A composition comprising: a) a first polymer or polymer mixture with a glass transition temperature (“Tg”) from 75° C. to 130° C.; b) a second polymer or polymer mixture with a Tg from 20° C. to 35° C.; and c) one or more cosmetically acceptable solvents; wherein when the first polymer or polymer mixture and the second polymer or polymer mixture are dissolved together in a cosmetically acceptable solvent, which may be the same as or different than the solvent in c), and then dried to form a film, the film has a tensile storage modulus at 20° C. of from 1×10 10 Pascal to 1×10 8 Pascal and a storage modulus at 70° C. of from 1×10 9 Pascal to 1×10 6 Pascal; and wherein the first polymer and the second polymer are independently selected from block, graft, and branched homopolymers and copolymers derived from one or more monomers selected from methacrylic acid; acrylic acid; methacrylate esters, acrylate esters, styrene, substituted styrenes, vinyl esters of organic acids, N-vinyl compounds, acrylamide; methacrylamide; substituted acrylamides, amine-functional acrylamides, substituted methacrylamides; hydroxylalkyl methacrylates, hydroxylalkyl acrylates, dienes, vinyl ethers, acid containing monomers; and functional monomers selected from maleic acid, maleic anhydride, fumaric acid, α-methylene glutaric acid, itaconic acid, itaconic anhydride, citraconic acid, mesaconic acid, cyclohexenedicarboxylic acid, 2-acrylamido-2-methylpropanesulfonic acid, monoacryloxyethyl , and water-soluble salts thereof.
