摘要： PROBLEM TO BE SOLVED: To synthesize the subject compounds satisfying demands on color, ease of use, and reactivity, not requiring the storage of a product for a specied time, capable of being synthesized in an economically permissible time, by adding one or more catalysts. SOLUTION: (A) A mono- or polyamine corresponding to X[-NH2 ] is reacted with (B) a compound corresponding to formula I at a temp. of 0-100 deg.C in a solution or in the absence of a solvent in an equivalent ratio of the primary amino group in the substance A to the C=C double bond in the component B of (1:2) to (1.5:1) in the presence of (C) 0.1-10wt.% based on solid substance of a catalytic component (e.g. 1,2,4-triazole) corresponding to formula II (R is NH2 , H, etc.; R to R are each NH2 , H or a 1-24C organic group) and then, optionally an excessive reaction component is distilled away to give the objective compound corresponding to formula III [X is an amino group bonded in a (cyclo) aliphatic state, etc.; R and R are each an organic group; (m) is >=1].
