In the present invention, a) 2 to 6 of the following structural units (A) (in the formula (A), R', R'', R 1 , R 2 , R 3 and R 4 are defined herein. M is an integer of 1 to 6); b) one or more articulated chains (one of each of these articulated chains concatenates two of structural units A). And c) with respect to a multi-aziridine compound having a molecular weight in the range of 600 daltons to 5000 daltons. The multi-aziridine compound can be used, for example, for cross-linking a carboxylic acid functional polymer dissolved and / or dispersed in an aqueous medium. [Selection diagram] None |
