Document Type and Number:
Japanese Patent JP3473238
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for improving the reliability such as light fasteness or durability of a photorecording medium containing a phthalocyanine compound in the recording layer and ameliorating signal characteristics after recording.
SOLUTION: This photorecording medium consists of a transparent substrate, a recording layer, a reflective layer and a protecting layer. The center metals of the recording layer are Al, Ga, In, Si, Ge and Sn and substituent -OP(=O) R1, R2 (R1, R2 are a hydrogen atom, a hydroxyl group, an alkyl group, an aryl group, an alkoxy group and an aryloxy group independently) and a chemical compound shown by formula are contained in the recording layer.
