ABSTRACT:
A hair spray fixative resin comprises a vinyl acetate/alkyl maleate half ester/N-substituted acrylamide terpolymer in a molar ratio of about 1.0 to 0.6-0.8 to 0.08-0.12, which is preferably produced by a suspension or solution polymerization process. Utilizing N-substituted acrylamides in place of isoborneol methacrylates in the terpolymer provides superior holding power over conventional hair fixative resins, at lower cost.
