ABSTRACT:
The present invention relates to novel first to fourth lactone compounds. The first lactone compound is represented by the formula (1),in the formula, X represents CH2, CH2CH2, O, S or NR1, and R1represents hydrogen atom, a straight-chain, branched or cyclic alkyl group of a carbon number of 1–10. Hydrogen(s) of the alkyl group may partially or entirely be replaced with fluorine atom(s). Furthermore, a part of the alkyl group may contain an atomic group containing oxygen atom, sulfur atom, nitrogen atom, carbon-carbon double bond, carbonyl group, hydroxy group or carboxyl group.
