    摘要： A naphthol derivative represented by the general formula (I), [wherein Y and Y′ indicate —(CONH)n—X or —COR; X is a phenyl group, a naphthyl group, an anthraquinonyl group, a benzimidazolonyl group or a carbazolyl group; R is a hydroxyl group, an alkoxy group having 1 to 6 carbon atoms, a halogen atom, a benzyloxy group, a phenyloxy group or a phenacyloxy group; R2 is a hydrogen atom, an alkaline metal, an alkyl group having 1 to 6 carbon atoms, an acyl group having 1 to 6 carbon atoms or a phenylalkyl group; Z is a group selected from the group consisting of a hydrogen atom, a halogen atom, a nitro group, a nitroso group and an amino group (Z may be substituted on any ring of the naphthalene ring); and n is an integer of 1 or 2; provided that R2 and Z do not simultaneously indicate a hydrogen atom when both R simultaneously indicate a hydroxyl group], and a process for producing the same. This naphthol derivative can be used as raw materials for synthesis, such as dyes, pigments, photosensitive materials and the like.
