The present invention relates to a low tone color photographic light-sensitive composition comprising organosilicon (IV) phthalocyanine and naphthalocyanine, wherein the production of singlet oxygen is increased by having a Q-band absorption maximum at a wavelength of 660 nm or more and an increased triplet state yield . When Si 4+ phthalocyanine and naphthalocyanine compounds are used in a photopotential composition, a low-hue washing composition, a bleaching composition and a hard surface cleaner can be produced. |
