摘要： PROBLEM TO BE SOLVED: To obtain an image recording material having a simple structure, good light resistance and hue reproducibility and capable of forming a black colored image excellent in color tone and to record a full-color image using the image recording material. SOLUTION: The recording material is a non-silver salt recording material with only recording layers containing a yellow coloring component, a magenta coloring component and a cyan coloring component as recording layers on the substrate. Each recording layer has a maximum absorbance of reflection of >=1.0 and 50-200 nm half-width in the case where the maximum absorbance is standardized as 1. In a region of the recording material in which a black image is formed, colored image formation is carried out under conditions which adjust the maximum coloring density of the coloring component in each recording layer to a prescribed value determined by the hue of the color, preferably >=1.2 and a black image is formed by the color mixture of colored images. In a region in which an image other than a black image is formed, colored image formation is carried out under conditions which adjust the maximum coloring density of the coloring component in each recording layer to below the maximum coloring density of black.

摘要： PROBLEM TO BE SOLVED: To obtain a photosensitive and heat sensitive transfer material which reduces the surface gloss of an image receiving material after the transfer of a photosensitive and heat sensitive transfer layer and gives paper-like appearance. SOLUTION: A photosensitive and heat sensitive transfer material including a photosensitive and heat sensitive transfer layer on the substrate is irradiated with light to form a latent image, the transfer material is brought into close contact with an image receiving material and a color developing component is allowed to develop a color by heating in accordance with the latent image to form a color image. The photosensitive and heat sensitive transfer layer is transferred to the image receiving material by peeling the substrate and the surface of the image receiving material with the transferred photosensitive and heat sensitive transfer layer is irradiated with light to fix and record the image. The photosensitive and heat sensitive transfer material includes a layer which becomes a peeled face on the image receiving material side by the peeling of the substrate and the surface of the layer is rough after the peeling of the substrate.

摘要： PURPOSE:To improve the preservability of a recorded image by adding a specific diazo compound to a thermal recording layer. CONSTITUTION:A thermal recording material consists of a thermal recording layer containing diazo compound, a compound which generates a coupling component base, or a base due to heating, and a binder on a support. A thermally recording material containing a diazo compound expressed by formula I is formed in said thermal recording layer. In the formula, R1 to R2 are hydrogen atom and a substitution or non-substitution alkyloxy group; R1 to R4 can be the same as or different from each other. R5, R6 are a 1 to 20C substitution or non-substitution alkyl group and aralkyl group. R5, R6 can be the same as or different from each other. R7 is a substitution or non-substitution lower alkylene group. X is an acid anion. A recorded image formed using a diazo compound expressed by the formula is less susceptible of chromatic fading due to light.
