Abstract
A urethane (meth)acrylate metal salt obtained by reacting (A) one or more polyisocyanates, (B) one or more hydroxy functional (meth)acrylates, and (C) one or more metal salt polyols which are the reaction product of a metal oxide and a half ester containing a hydroxy group and a carboxylic acid group. Processes of preparing such salts and polymers prepared from such salts are also disclosed. The polymers are useful for coating and adhesive compositions prepared by radiation or peroxide curing processes.
