摘要

"Modifications of modified polyolefin, base - based coating, water - based coating and modified polyolefin coating, process for the preparation of coated substrate, and,". Polyolefins modified by the reaction of a functionalized polyolefin with one or more ethylenically unsaturated compounds having a functional group reactive with the polyolefin functional group are produced. These polyolefins may then polymerize in the presence of a photoinitiator and exposure to ultraviolet radiation, and also have the ability to copolymerize in the presence of a photoinitiator with other ethylenically unsaturated crosslinking agents also by exposure to ultraviolet radiation. Such modified polyolefins may further contain pendant carboxyl groups which have the propensity to form hydrophilic salts with amines and may therefore be made dispersible in water. The modified polyolefins of the present invention significantly improve the adhesion of inks, printing inks and adhesives to various plastic and metal substrates.
