Abstract
Abstract A polyamide resin composition for use as laminating ink resin binder is provided by the condensation reaction product of dimerized fatty acids having 36 carbon atoms, at least one dibasic acid, at least one C 1 -C 4 alkyl diamine and at least one piperazine-like diamine. The equivalents of amine groups in the composition are substantially equal to the equivalents of carboxyl groups, where 30 to 50 equivalent perecent of the carboxyl groups are contributed by the dibasic acid component and 73 to 93 equivalent percent of the amine groups are contributed by the piperazine-like diamine component. Printing inks with the polyamide resin composition of this invention are also provided.
