Claim:
A carboxylic acid compound represented by the formula: wherein L represents a single bond, a C1 to C6 alkylene group or a C2 to C6 alkynylene group; M represents a C1 to C6 alkylene group; T represents a single bond, a C1 to C3 alkylene group, or a C2 to C3 alkynylene group; W represents a carboxyl group; represents a single bond; X represents an oxygen atom or a group represented by —NR X1 CQ 1 O—, wherein Q 1 represents an oxygen atom; and R X1 represents a hydrogen atom, —OCQ 1 NR X1 , wherein Q 1 and R X1 each represent the same groups as defined above, and —CQ 1 NR X1 —, wherein Q 1 and R X1 each represent the same groups as defined above; Y represents a 5 to 14-membered aromatic group which may have one or more substituents selected from the following substituent group and one or more hetero atoms wherein: the substituent group is selected from the group consisting of: a halogen atom, an alkyl group which may be substituted with 1 to 3 halogen atoms, an alkoxyl around which may be substituted with 1 to 3 halogen atoms, a C3 to C8 cycloalkyl group, a C3 to C8 cycloalkyloxy group, a methylenedioxy group, a thienyl group which is substituted with a C1 to C6 alkyl group, and a phenyl group which may be substituted with 1 to 3 halogen atoms, a C1 to C6 alkyl group or a C1 to C6 alkoxyl group; the ring Z represents a 5 to 14-membered aromatic group which may have 1 to 4 substituent groups selected from the group consisting of a halogen atom, a hydroxyl group and a C1 to C6 alkoxyl group, and one or more hetero atoms, and the ring U represents a 5 to 14-membered aromatic group which may have 1 to 4 substituent groups selected from the group consisting of a halogen atom, a hydroxyl group, a C1 to C6 alkyl group, and a C1 to C6 alkoxyl group, and one or more hetero atoms.
