Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to a heat-developable photosensitive material, and more specifically, it has poor antistatic properties during manufacturing, heat development, etc., has good releasability from an image-receiving element after transfer, and has sufficient transfer properties. The present invention relates to a heat-developable photosensitive material that provides image density. [Background of the Invention] In recent years, heat-developable photosensitive materials whose development process can be performed by heat treatment have attracted attention as photosensitive materials. Regarding such heat-developable photosensitive materials, for example,
No. 4921 and No. 43-4924 disclose a photosensitive material comprising an organic silver salt, silver halide, a reducing agent, and a binder, which is commercialized as dry silver by 3M Company. Attempts have been made to improve such heat-developable photosensitive materials and obtain color images by various methods. For example, U.S. Patent Nos. 3,531,286 and 3,7

Various methods have been proposed, such as the method of obtaining a dye image using a leuco dye disclosed in No. 83 and Japanese Patent Application Laid-Open No. 59-206831. However, these proposals regarding the heat-developable color light-sensitive materials are difficult to bleach and fix the black and white limit images formed at the same time, difficult to obtain clear color images, and complicated. However, it is still unsatisfactory for practical use because it requires extensive post-treatment. In recent years, a new type of color image forming method using heat development has been developed, as disclosed in Japanese Patent Application Laid-open Nos. 11I57-179840 and 57-1.

The basic composition of a color type heat-developable photosensitive material that obtains a dye image using these released or formed diffusive dyes consists of a light-sensitive element and an image-receiving element, and the light-repelling element is basically a photosensitive silver halide. , a Rm-containing salt, a reducing agent, a dye-providing substance, and a binder, and the image-receiving element has an image-receiving layer. In the present invention, the above-mentioned photosensitive element and receiver l! j! Both elements are collectively referred to as a photothermographic material. Note that hereinafter, the photosensitive element will be referred to as a heat-developable photosensitive material or simply a photosensitive material, and the image receiving element will be referred to as an image receiving member. The above-mentioned heat-developable photosensitive material is one in which a dye image is obtained by transferring the released or formed diffusible dye onto the image receiving layer of an image receiving member provided on the same support or on an independent support. It was improved in many respects compared to previous heat-developable color photosensitive materials in terms of image sharpness, stability, etc. As a further improvement of the above-described heat-developable photosensitive material, a release layer is provided on the so-called beer-apart-type photothermographic material in which the transferred image is obtained by separating the photosensitive material r[ and the image receiving member during heat development transfer. A patent application filed in 1983 describes a technology in which a layer contains an organic fluorosurfactant and a part of one photosensitive material or image receiving member is quickly peeled off without adhering to the other.
-1469. Belgian Patent No. 742,680 discloses that the use of fluorinated surfactants as coating aids in hydrophilic colloid coating compositions provides antistatic effects while maintaining advantageous coating qualities. It is stated that. However, when a layer containing the organic fluorosurfactant is provided on a heat-developable photosensitive material on the surface that contacts the image-receiving member, even though the photo-sensitive material and the image-receiving member are in close contact with each other during heat-developable transfer, The problem is that the presence of released fluorosurfactants inhibits dye transfer, making it difficult to obtain high-22 degree images after heat development, transfer, and peeling. As a method to solve the above problems, the present inventors have decided to use a compound that exhibits a thickening function. We have discovered a technology that improves As a result of experimenting with the use of various additives as compounds exhibiting a thickening function, the present inventors have found that they have good compatibility and dispersibility with various compounds and binders used in photothermographic materials, and , when used in combination with an organic fluorosurfactant,
It has been found that a nonionic water-soluble polymer is optimal as it satisfies all of releasability, antistatic properties, and transferability. By the way, the technique of adding a nonionic hydrophilic polymer to the protective layer of a heat-developable photosensitive material is disclosed in Japanese Patent Application Laid-open No. 60-120357.
However, this is because when using a dye fixing layer containing a polymer mordant having a cationic site by using a nonionic wood-philic polymer, adhesion due to electrostatic action is improved. This shows the effect of improving the releasability after heat development. However, when an organic fluoro compound and a nonionic hydrophilic polymer are used in combination as in the present invention, the effects of improving peelability and antistatic properties are much greater than when only a nonionic hydrophilic polymer is used. This discovery led to the present invention. [Objective of the Invention] The object of the present invention is to provide a transfer image with excellent antistatic properties during manufacturing, development and transfer processing, etc., good releasability from the dye image receiving member after image transfer, and a transfer image with sufficient density. The object of the present invention is to provide a heat-developable photosensitive material that can be used as a photothermographic material. [Configuration of the Invention] The above objects of the present invention are achieved by a photothermographic material containing an organic fluorosurfactant and a nonionic water-soluble polymer. C Specific Structure of the Invention] In the present invention, an organic fluorosurfactant (hereinafter simply referred to as an organic fluoro compound) is defined as having at least one, preferably three or more, fluorine atoms in the molecule and at least one, preferably three, fluorine atoms. is a compound having three or more carbon atoms, and also includes a polymer compound having a fluorine atom and a carbon atom in the main chain or side chain.

In the same way as in Example 2, the conditions listed in Table 5 are provided.
Fluorinated and nonionic water-soluble compounds as shown
Contains a polymer. However, the gelatin in Ho 5 is 0.
, 42o/y. Pass the step wedge through the heat-developable photosensitive material-2.
Then, a frost light of 3,200C, M, S was applied to the image receiving surface.
Superimposed with member-2, 1 with the same visual image moon as Example-1
After heating at 50℃ for 1 minute, immediately heat the image receiving member.
I tore it off. A yellow transparent image was obtained on the surface of the image receiving member. In the same manner as in Example-1, antistatic properties, peelability and transferability were tested.
The photographic quality was evaluated. The results are shown in Table 5 below. Similar to the results of Margin Example-1 below, compared to the comparative example, the paid fluorescent
Trial using 01 compound and nonionic water-soluble polymer
Material, N, O, P and Q are antistatic property, peelability, transfer property.
A heat-developable photosensitive material with comprehensively improved properties can be
did it. Patent applicant Konishiroku Photo Industry Co., Ltd. Procedural amendment (voluntary) February 18, 1986
