摘要：
This invention provides a novel halogen-containing ester compound represented by the following general formula (I): ##STR1## (wherein R is an alkyl group, A is selected from a single bond, --O--, --COO-- and --CO--, both of X and Y are halogen atoms or either one of X and Y is a halogen atom and the other is a hydrogen atom, each of m and n is 0 or 1, m+n=0 or 1, each of k and l is an integer of 1 or more, provide k
