This invention relates to curable composition comprising a carbamate resin and a crosslinking compound having the structure of Formula (I): wherein Z is a hydrogen, an alkyl of 1 to about 18 carbon atoms, an aryl of about 6 to about 24 carbon atoms, an aralkyl of about 7 to about 24 carbon atoms or -NR5CH2OR6; R1, R4 and R5 are each independently hydrogen, -CH2OR6, an alkyl of 1 to about 18 carbon atoms, an aryl of about 6 to about 24 carbon atoms or aralkyl of about 7 to about 24 carbon atoms, with the proviso that at least one R1, R4, and R5 is an alkyl, aryl or aralkyl; R2, R3 and R6 are each independently hydrogen, alkyl, aryl, aralkyl, alkoxyalkyl or an alkaryl having from 1 to about 24 carbon atoms. Another embodiment of this invention is waterborne curable composition comprising the crosslinking compound of Formula (I), a carbamate resin and water.
Cette invention concerne une composition durcissable comprenant une résine de carbamate et un composé réticulant de formule (1) dans laquelle Z est hydrogène, un alkyle comprenant de 1 à environ 18 atomes de carbone, un aryle comprenant de 6 à 24 atomes de carbone environ et un aralkyke comprenant de 7 à 24 atomes de carbone environ, ou -NR¿5?CH¿2?OR¿6?; R¿1?, R¿4? et R¿5? sont chacun indépendamment hydrogène, -CH¿2?OR¿6?, un alkyle comprenant 1 à environ 18 atomes de carbone, un aryle comprenant de 6 à 24 atomes de carbone environ ou un aralkyle comprenant de 7 à 24 atomes de carbone environ, à condition qu'au moins un de R¿1?, R¿4?, et R¿5? soit un alkyle, un aryle ou un aralkyke; R¿2?, R¿3? et R¿6? sont chacun indépendamment hydrogène, alkyle, aryle, aralkyle, alkoxyalkyle ou un alkaryle comprenant de 1 à environ 24 atomes de carbone. Dans un autre mode de réalisation, cette invention concerne une composition en phase aqueuse durcissable comprenant le composé réticulant de formule (1), une résine de carbamate et de l'eau.
