AQUEOUS COLD SEAL RELEASE LACQUER

摘要

An aqueous cold seal release varnish comprising the reaction product of a mixture comprising 30-50 parts of a polyamide block copolymer having an acid value of 30-45, 1-5 parts of an amide wax, 10-20 parts of at least one C1-C4 alkanol, 5-10 parts of an amine and 15-55 parts of water. The mixture is dissolved by heating at a temperature of 75.degree.-85.degree.C for a period of time of not more than 90 minutes to produce a varnish. An aqueous cold seal release lacquer (CSRL) is prepared from the varnish by mixing with a C1-C4 alkanol, water and a surfactant.
