  • Patent number: 7687229
    Abstract: A silver halide color photographic light-sensitive material having, on a support, at least each one light-sensitive silver halide emulsion layers containing yellow-, magenta-, or cyan-dye-forming-coupler, and at least one light-insensitive hydrophilic colloid layer, wherein at least one of the dye-forming couplers is a dye-forming coupler that forms an azomethine dye having a solubility of 1×10?8 mol/L to 5×10?3 mol/L in ethyl acetate; and an image forming method using the light-sensitive material.
    Type: Grant

  • Publication number: 20080274332
    Abstract: The present invention presents an optical recording medium capable of forming visible images of excellent visibility by using laser light, and a method for manufacturing the same. An optical recording medium has a first substrate on which an information recording layer and an image recording layer are formed in this order, and a second substrate formed on the image recording layer, in which a surface of the image recording layer side of the second substrate is roughened.

  • Publication number: 20060024624
    Abstract: A heat-developable color light-sensitive material containing light-sensitive silver halide grains, a binder, at least one compound of formula (I), and at least one dye-providing compound of formula (II), on a support, wherein at least one of layers containing the light-sensitive silver halide grains contains the binder, the compound of formula (I), and the dye-providing compound of formula (II) and, wherein the heat-developable color light-sensitive material contains no compound that participates in a coupling reaction with an oxidized product of the compound of formula (I): Formula (I) wherein Z represents a carbamoyl, acyl, alkoxycarbonyl, aryloxycarbonyl, sulfonyl, or sulfamoyl group; and Q1 represents a group of atoms necessary to form an unsaturated ring; Formula (II) wherein DYE represents a dye or dye precursor group; Y represents a specific group; X represents a simple bond or a connecting group; p denotes 1 or more, and q denotes 1 or 2.
