Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
123 words
A sprayable temporary curl setting composition comprising at least one water soluble, reactive polyamide-epichlorohydrin resin having the formula: ##STR2## wherein R is an alkyl group containing from 1 to about 6 carbon atoms, R 1 and R 2 are independently alkyl groups containing at least 2 carbon atoms, and n is the number of repeating units in the water soluble molecule and at least one water soluble vinylpyrrolidone polymer dissolved in a solvent-carrier for said resin and polymer, wherein the resin and polymer concentration of said composition are independently from about 0.5 to about 8 percent by weight based on the weight of resin, polymer and solvent-carrier and wherein the weight ratio of resin to polymer is from about 1:2 to about 2:1.
Claim 2
Dependent Claim
123 words
