As the gelatin hardener to be added to the first timing layer, e.g., aldehyde type compds., compds. having reactive halogen, and epoxy compds. are preferable. As a mordant layer to be used for the image receiving element, a gelatin layer contg. a polymer mordant is preferable.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical field to which the invention is applied) The present invention relates to an image receiving element for a peelable color diffusion transfer method.

(Prior Art) In the peel-off type color diffusion transfer process, the receiving element is a photosensitive element comprising at least one photosensitive silver rodanide emulsion layer and a dye (donating compound) combined therewith. The photosensitive element is imagewise exposed to light and then processed (developed) with an alkaline processing composition.The diffusible dye formed from the dye image-donating adduct as a result of development is used in combination with After being diffused into the image-receiving element, the image-receiving element is separated from the photosensitive element.In this way, in the peel-off type color diffusion transfer method, a stronger physical action called "peeling" is added than in the non-peel-off type. Furthermore, the image-receiving element is also required to have ``severe film physical properties.'' This is because if the interlayer adhesion between the layers constituting the image-receiving element is not good, part of the image-receiving element may peel off when the image-receiving element is separated from the photosensitive element. In addition, the treated image-receiving element is also required to have strong adhesion between each layer, so after gluing adhesive tape such as cellophane tape over the image on an album or wall, If the image fades when the tape'kH is used again, it will be a fatal defect.Especially, in addition to the conventional timing layer in contact with the neutralization layer, there is another layer in contact with the mordant layer. By installing Timing Ii# (first timing layer), relatively high image density (1) is achieved even when shooting (processing) at low temperatures.
max) has been reduced to 41, which has the effect of reducing the so-called processing IT dependence (increasing the processing temperature latitude). It has been found that the interlayer adhesion between the first timing layer and the mordant layer deteriorates in the element. In order to improve these adhesion properties, it is possible to consider measures such as providing an intermediate layer between the VC layers to improve adhesion, but this often has an adverse effect on photographic properties such as an increase in rx Dm t n. Process-wise advantages are disadvantageous in terms of cost.

(Object of the Invention) An object of the present invention is to provide an image-receiving element for a peelable color diffusion transfer method that does not peel off inside the image-receiving element when the two elements of the image-receiving element and the photosensitive element are separated.

A further object of the present invention is to provide an image-receiving element for a peel-off type color diffusion transfer method that has excellent adhesion between the layers after drying and during storage.

It is a further object of the present invention to provide an image-receiving element for a peel-off type color diffusion transfer method that has improved adhesion performance without adversely affecting photographic performance.

(Summary of the Invention) As a result of intensive research, the present inventors have found that at least 1) a neutralization layer, 2) a fourth timing layer, and 3) a polymer latex are all coated on a support in order from the support. a first timing layer; 4) an image-receiving element coated with a mordant layer containing gelatin, characterized in that the first timing layer contains a gelatin hardener that has a hardening effect even in polymer latex; It has been found that the above-mentioned objectives can be effectively achieved by using an image receiving element for a peelable color diffusion transfer method.

(Effects of the Invention) According to the present invention, the interlayer adhesion between the first timing layer coated with polymer latex and the mordant layer containing gelatin is significantly improved.

In practice, a mordant layer containing seratin is usually lightly hardened, but the effect of interlayer adhesion cannot be obtained as much as has been done in the past. On the other hand, if the mordant layer is hardened with strong IfVC, the mordant effect is inhibited, so the transfer 1111f (Dma
There was a dilemma that x) could not be obtained.

In the present invention, by coating the polymer latex coating solution for the first timing layer with the above-mentioned gelatin hardener and a substance that promotes hardening as desired, the first timing can be applied without impairing photographic properties. The adhesion between the layer and the mordant layer can be improved, but even if a substance such as gelatin hardener is added to this layer, the first timing layer and the mordant layer will not harden and will not harden specifically at the interface between both layers. This is because a crosslinking reaction occurs. This kind of effect was unexpected and could not be known until it was tried.

As the light-sensitive element that can be used in combination with the image-receiving element of the present invention, conventionally known ones can be used, and generally it consists of a support coated with at least one silver halide emulsion layer combined with a dye-providing compound. It is. The silver halide emulsion used here may be a so-called 1-negative emulsion or a direct positive emulsion that does not require reversal treatment. Direct positive emulsions [i] There are two main types: pre-fogged type and internal:a image type, but the latter is preferred because it provides high sensitivity. In addition, conventionally known compounds that form or release diffusible dyes in the form of 1kl@ as a result of development can be used as dye-donating additives, typically redox compounds that release all of the diffusible dyes or Any coupler or dye developer that becomes diffusible under alkaline conditions may be mentioned.
