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 C.sub.1 -C.sub.4 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 C.sub.1 -C.sub.4 alkanol, water and a surfactant.
摘要:
Printing inks comprising a pigment and an aqueous or non-aqueous solvent (or a mixture of such solvents) have reduced abrasiveness towards printing surfaces (e.g. gravure printing cylinders) by incorporation in the ink of an alkoxylated dibasic phosphate ester and at least one alkali metal salt of a dialkylsulfosuccinic ester.
摘要:
The present invention describes a two-sided radiation exposure method including a step of applying a coating or ink composition on a surface of a nonporous substrate. The applied coating or ink composition surface of the nonporous substrate is exposed to radiation one or more times. In addition, a non-applied surface of the nonporous substrate is exposed to radiation one or more times. The two-sided radiation exposure method improves adhesion and/or curing properties of the coating or ink composition applied on the nonporous substrate. The present invention also describes a radiation exposed, nonporous substrate with a coating or ink composition applied on a surface thereof produced by the steps of the above-mentioned method.
