wherein Z is [i], [ii], or [iii] below, and n is an integer of 2 to 10,
(wherein R
1
and R
2
are each independently a lower alkyl group having 1 to 5 carbon atoms, R
3
is a hydrogen atom or a lower alkyl group having 1 to 5 carbon atoms, and a is 1 or 2). The carbamate ester compound is used as a vulcanizing agent for carboxyl group-containing acrylic rubber and improves the delay of the vulcanization rate by scorch suppression.
