PURPOSE:To obtain a CD-R recording film material conforming to an orange book standard and excellent in durability by introducing an alkoxy group and a nitro group into the respective benzene rings of a phthalocyanine skeleton represented by a specific formula and using a fluorine substituted alkoxy group and a non-substituted alkoxy group as the alkoxy group. CONSTITUTION:An alkoxy group and a nitro group are introduced into each of four benzene rings of a phthalocyanine skeleton represented by formula (wherein M is a hydrogen atom or a metal atom which may be substituted with an oxygen atom, a hydroxyl group or a halogen atom) and, as the alkoxy group, (n) fluorine substituted alkoxy groups and (m) non-substituted groups (wherein n and m are an integer of 1-3, and n+m is 4) are used. The alkoxy group is introduced into four benzene rings of the phthalocyanine skeleton represented by the formula at one of substitution positions of l or 4, 5 or 8, 9 or 12, 13 or 16 and the nitro group is introduced thereinto at the other one of the substitution positions of them. |
