    • The present invention pertains to carbamate-melamine formaldehyde cross-linking agents of the formula (I), wherein X is selected from the group consisting of -COOR, -(CH2-O)l-H, -(CH2-O)l-R, -(CH2-O)k-CH2-N(X)-Q, and -(CH2-O)k-CH2-N(Y)-Q; Y is independently selected from the group consisting of -H, -(CH2-O)l-H, -(CH2-O)l-R, -(CH2-O)k-CH2-N(X)-Q, and -(CH2-O)k-CH2-N(Y)-Q; with each k independently being 0-10, and each l independently being 1-10;each R being independently selected from the group consisting of alkyl, cycloalkyl, and alkylaryl groups; Q being (II) and wherein said agents comprise, on average , at least 0.05, but fewer than 2 carbamate groups per triazine moiety. The present invention further relates to the preparation of these types of cross-linking agents, to a curable coating composition comprising said cross-linking agents and at least one polyhydroxy group-containing polymer, and to the use of said curable coating composition.
    • 本发明涉及式(I)的氨基甲酸酯 - 三聚氰胺甲醛交联剂,其中X选自-COOR, - (CH2-O)1H, - (CH2-O)1R, - ( (X)-Q和 - (CH2-O)k-CH2-N(Y)-Q; Y独立地选自-H, - (CH 2 -O)1 H, - (CH 2 -O)1 R, - (CH 2 -O)k -CH 2 -N(X)-Q和 - O)K-CH2-N(Y)-Q; 每个k独立地为0-10,并且每个l独立地为1-10;每个R独立地选自烷基,环烷基和烷基芳基; Q为(II),并且其中所述试剂平均每个三嗪部分包含至少0.05个但少于2个氨基甲酸酯基团。 本发明进一步涉及这些类型的交联剂的制备,包含所述交联剂和至少一种含多羟基基团的聚合物的可固化涂料组合物,以及所述可固化涂料组合物的用途。
