1. A fixative polymer for a hair styling composition, the polymer in the form of a latex made by emulsion polymerization, having a weight-average molecular weight of 50,000 to 300,000, and comprising, as polymerized units,
(i) 15% to 75% by weight, based on the weight of said polymer, of one or more monomers having a refractive index of 1.490 or higher; (ii) 2% to 15% by weight, based on the weight of said polymer, of one or more non-ionic water soluble monomers having the formula: wherein R1 is hydrogen or methyl; Z is —(C═O)O— or —(C═O)NH—; R2 is hydrogen, a C1-C18 alkyl, phenyl, styrenol, or carboxyl; and n is 1-50; (iii) 12% to 30% by weight, based on the weight of said polymer, of one or more acid-functional monomer; and (iv) 5% to 69% by weight, based on the weight of said polymer, of one or more additional monomer, with the proviso that said one or more additional monomer is different from monomers (i), (ii) and (iii), and is selected from the group consisting of olefins, dienes, C1-20 alkyl (meth)acrylate monomers, C1-10 hydroxyalkyl (meth)acrylate monomers, and a combination thereof. |
