Summary:PROBLEM TO BE SOLVED: To industrially inexpensively obtain the subject compound by Michael addition of a moisture-contg. amine compound, without dehydrating it in advance, to a (meth)acrylic ester followed by dehydration to effect diminishing the loss in the amine compound. SOLUTION: This compound, (C) a (meth)acrylamide derivative, is obtained by Michael addition of (A) a moisture-contg. amine compound of formula I (R1 is H or a CiH2i+1; R2 is CkH2k; R4 is ClH2l; k and l are each a natural number of 2-4) to (B) a (meth)acrylic ester of formula III (R5 is H or CH3; R6 is CmH2m+1; m is a natural number of 1-4) followed by dehydration to effect amidation followed by thermal decomposition; wherein the component A may contain the matter recovered from the production process for the component C as the final product, and it is preferable that, in the dehydration after the Michael reaction, the moisture content of the resulting Michael adduct is brought to <=400 ppm.
