Crosslinking photoinitiators of acrylic benzophenonetetracarboxylates

摘要

A method of forming an acrylic polymer coating on a substrate wherein the coating is cured with ultraviolet light. Photoinitiation of the crosslink reaction is provided by a benzophenone moiety in the crosslinking agent. The photoinitiator moiety is an integral part of the chain, thereby producing a relatively fast cure rate while contributing strength and coherence to the network.
