Abstract

L'invention concerne une composition de résine durcissable qui permet de former un film mince de résine durcie par application sur la surface d'un substrat de verre, qui résiste à une cuisson à 230°C, et qui permet un pelage facile et sans efforts vis-à-vis du substrat. Cette composition de résine durcissable contient un polymère sous forme de chaîne équipé d'une chaîne latérale possédant un groupe hydroxy secondaire ou tertiaire alcoolique, et un agent de réticulation. (a) Cette chaîne latérale contient 3 à 30 atomes de carbone, contient également soit au moins un groupe hydrocarbure saturé ou insaturé, soit au moins un groupe aromatique en addition de ce ou de ces groupes hydrocarbure, et peut contenir une liaison choisie dans un groupe constitué de －ＣＯＯ－, －Ｏ－ et －ＣＯ－ liant les atomes de carbone entre eux. (b) L'agent de réticulation est choisi dans un groupe constitué d'un composé à base de triazine et/ou de son condensat, d'un composé à base de glycoluril et/ou de son condensat, et d'un composé à base de imidazolidinone et/ou de son condensat.
