摘要:
The invention relates to a crosslinker composition comprising a reaction product of a cyclic urea U and a multifunctional aliphatic aldehyde A , and at least one crosslinker selected from the group consisting of reaction products of an aminotriazine and at least one aldehyde selected from the group consisting of aliphatic monoaldehydes and multifunctional aliphatic aldehydes having the structure Y(CHO) n , where Y is an n-functional aliphatic residue, and n is greater than 1; reaction products of urea and/or cyclic ureas and aliphatic monoaldehydes; alkoxycarbonylaminotriazines; multifunctional isocyanates which may be partially or completely blocked; reaction products of phenols and aliphatic monoaldehydes; multifunctional epoxides; multifunctional aziridines; and multifunctional carbodiimides, wherein any of the crosslinkers which have hydroxyl groups may be etherified with one or more linear, branched, or cyclic aliphatic alcohols.
