Japanese Patent JP4372991
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a recording material suitable as a large-capacity and additional-type recording material, capable of corresponding even if shortening of a laser wavelength. SOLUTION: This recording material is a porphyradine compound represented by the general formula (1) (wherein, X1-X4 denote each hydrogen, a halogen atom, (un)substituted alkyl group, (un)substituted phenyl group, (un)substituted alkoxy group, and (un)substituted aryloxy group; Y1-Y4 denote each independently hydrogen atom, a fluorine-substituted alkoxy group, (un)substituted five- membered heterocycle, and this five-membered heterocycle may condense with another aromatic ring or heterocycle, and binds with a porphyradine ring at the position of a nitrogen atom, wherein at least one of Y1-Y4 contains the heterocycle. Mt represents two hydrogen atoms, or represents oxygen, a halogen atom, or a divalent, trivalent or tetravalent metal atom capable of having other ligand).
