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.

La présente invention concerne un sel métallique d'uréthanne (méth)acrylate obtenu par la réaction (A) d'un ou des polyisocyanates, (B) d'un ou des (méth)acrylates comportant des groupements hydroxyles fonctionnels, et (C) un ou des polyols de sel métalliques qui sont le produit réactionnel d'un oxyde métallique et d'un demi-ester contenant un groupement hydroxyle et un groupe d'acide carboxylique. L'invention concerne également des procédés de préparation de tels sels et des polymères préparés à partir de tels sels. Les polymères sont utiles aux compositions de revêtement et adhésives obtenues par des procédés de traitement par rayonnement ou au peroxyde.
