Title:

ORGANIC SALT COMPOUND, AND OPTICAL RECORDING MATERIAL AND OPTICAL RECORDING MEDIUM USING THE ORGANIC SALT COMPOUND

Document Type and Number:

WIPO Patent Application WO/2010/137432

Kind Code:

A1

Abstract:

An organic salt compound, which comprises a monomethine cyanine cation represented by general formula (I) and an azomethine complex anion represented by general formula (IV), having high sensitivity and good light resistance and being appropriate, in particular, for optical elements to be used optical recording materials for recording and reproducing information using laser beams. In general formula (I), X represents an oxygen atom, a sulfur atom or a selenium atom; R1 and R2 represent a C1-20 alkyl group, a C7-30 arylalkyl group, or the like; R3 to R6 represent a hydrogen atom, a C1-20 alkyl group, or the like, provided that R4 and R5 may be bonded together to form a 6-membered ring; Y1 and Y2 represent a C1-20 alkyl groups, or the like; and R7 to R10 represent a hydrogen atom, a C1-20 alkyl group, or the like, provided that adjacent groups among R7 to R10 may be bonded together to form a 5- or 6-membered ring. In general formula (IV), M' represents Fe, Co, Ni, Cr, Mn, or the like; and R11 to R26 represent a hydrogen atom, a nitro group, -NRR' (wherein R and R' represent a C1-4 alkyl group), or the like.
