Provided are a naphthalenedithiol or a derivative thereof that can achieve both high refractive index and high dissolubility (compatibility), and a process for producing the same and a use therefor. A naphthalene compound of the present invention is represented by the formula (1): wherein R1 and R2 independently represent a hydrogen atom or a substituent, R3 represents a substituent, and n denotes an integer of 0 to 6. At least one of R1 and R2 may represent the substituent. The naphthalene compound of the formula (1) may be dissolved in or mixed with an organic solvent to prepare a mixture (or blend); a curable composition containing the naphthalene compound of the formula (1) may be prepared; a resin of the present invention at least contains a constituent unit represented by the formula (1P): wherein R3 represents a substituent, and n denotes an integer of 0 to 6.
A naphthalene compound represented by the following formula (1):
A mixture containing a naphthalene compound represented by the following formula (1):
A curable composition containing a naphthalene compound represented by the following formula (1):
(canceled)
A curing agent for curing an epoxy resin, which is represented by the following formula (1):
A resin at least containing a constituent unit represented by the following formula (1P):
A method for improving a dissolubility or compatibility of a naphthalene compound in an organic compound, the naphthalene compound having sulfur atoms directly bonded to a naphthalene ring thereof at least at two positions, wherein the improvement comprises including the sulfur atoms at least at the 1,6-positions.
A resin composition at least containing a compound represented by the following formula (1):
