Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
90 words
An epoxy curable resin composition comprising an adduct of: (a) at least about three equivalents of a polyamine resin substantially free of polyamide groups containing at least two primary amine groups, and one secondary or tertiary amine group said polyamine resin having a fatty tail, and; (b) one equivalent per three equivalents of component (a) of a polyfunctional acrylic compound which is an ester of a member selected from the group consisting of acrylic acid and methacrylic acid and mixtures thereof and at least an equivalent amount of a polyol.
Claim 2
Dependent Claim
90 words
An epoxy curable resin composition comprising an adduct of: (a) at least about three equivalents of a polyamine resin substantially free of polyamide groups containing at least two primary amine groups, and one secondary or tertiary amine group said polyamine resin having a fatty tail, and; (b) one equivalent per three equivalents of component (a) of a polyfunctional acrylic compound which is an ester of a member selected from the group consisting of acrylic acid and methacrylic acid and mixtures thereof and at least an equivalent amount of a polyol.
Claim 3
Dependent Claim
26 words
