Patent ID: 7696380

Claim:
A mixture of at least two amide-based compounds represented by General Formula (1): wherein a represents an integer of 2 to 6, R 1 represents a C 2-30 saturated or unsaturated aliphatic polycarboxylic acid residue, and said aliphatic polycarboxylic acid residue has a valency of 2 to 6, and the two to six R 2 groups are the same or different, and each represent a trans-2-alkylcyclohexylamine residue represented by General Formula (a): wherein R 3 represents a C 1-10 linear or branched alkyl group, or a cis-2-alkylcyclohexylamine residue represented by General Formula (b): wherein R 3 represents a C 1-10 linear or branched alkyl group, the trans-2-alkylcyclohexylamine residue represented by General Formula (a) being present in a proportion of at least 70 mole % but less than 100 mole % of the total 2-alkylcyclohexylamine residues in the mixture.
