Abstract
Abstract Disclosed are novel aminopolyamide-acrylamide-glyoxal resins useful as a sizing agent for paper having low water absorption, a desirable property for sized paper. The products are water dispersible and/or soluble and also find utility in printing inks, textile treatment and cosmetic or beauty aid compositions. The aminopolyamide is the condensation product of a polymeric fat acid and polyalkylene polyamine.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
83 words
An aminopolyamide-acrylamide-glyoxal resin prepared by reacting a. a polymeric fat acid aminopolyamide having an amide number of about 150 to 600 b. an amount of an unsaturated amide sufficient to react with substantially all the amine groups in the aminopolyamide, said unsaturated amide having the formula ##STR3## where R'is hydrogen or an alkyl group containing up to 6 carbon atoms and c. reacting the resulting aminopolyamideunsaturated amide adduct with about 0.3 to 1.5 moles of glyoxal per amide group present in said adduct.
Claim 2
Dependent Claim
83 words
An aminopolyamide-acrylamide-glyoxal resin prepared by reacting a. a polymeric fat acid aminopolyamide having an amide number of about 150 to 600 b. an amount of an unsaturated amide sufficient to react with substantially all the amine groups in the aminopolyamide, said unsaturated amide having the formula ##STR3## where R'is hydrogen or an alkyl group containing up to 6 carbon atoms and c. reacting the resulting aminopolyamideunsaturated amide adduct with about 0.3 to 1.5 moles of glyoxal per amide group present in said adduct.
Claim 3
Dependent Claim
62 words
A resin as defined in claim 1 wherein said aminopolyamide is the reaction product at a temperature in the range of about 100 to 300° C. of a polymeric fat acid and a polyamine of the formula H.sub.2 NR(NHR).sub.ρ NH.sub.2 where R is an alkylene radical containing about 2 to 6 carbon atoms and p is a positive integer less than 6.
