The present invention provides a reaction product having polyether carbamate groups formed from (A) polyoxyalkylene amine, and (B) cyclic carbonate, in an equivalents ratio ranging from 1:0.5 to 1:1.5. Further provided is a process for preparing the aforementioned reaction product. The present invention also is directed to an improved curable coating composition including (1) a reactive functional group-containing polymer, and (2) a curing agent having functional groups reactive with the functional groups of (1), the improvement being the inclusion in the coating composition the reaction product. Multilayer composite coatings including a first coating layer formed from the curable coating composition and a second coating layer over the curable coating composition are also provided, as well as coated substrates.

La présente invention concerne un produit de réaction possédant des groupes de carbamate de polyéther formés à partir (A) d'amine de polyoxyalkylène et (B) de carbonate cyclique, dans un rapport d'équivalents s'étalant entre 1:0,5 et 1:1,5. Cette invention a aussi trait à un procédé permettant de préparer le produit de réaction susmentionné, et à une composition de revêtement réticulable renfermant (1) un polymère à groupe fonctionnel réactif, et (2) un agent de réticulation possédant des groupes fonctionnels réagissant avec les groupes fonctionnels (1), l'amélioration reposant sur l'inclusion du produit de réaction dans la composition de revêtement. Ladite invention concerne des revêtements composites multicouches englobant une première couche de revêtement formée à partir de la composition de revêtement réticulable et une seconde couche de revêtement placée sur la composition de revêtement réticulable, ainsi que des substrats recouverts.
