Abstract

PURPOSE:To obtain a wash-off photosensitive material good in erasability by rubber, and also good in adhesion of an image, by incorporating a polymer latex in a layer formed above a subbing layer. CONSTITUTION:A subbing layer and a silver halide emulsion layer contg. a tanning developing agent are formed on a support in this order to obtain a silver halide photosensitive material. A polymer latex having a structure of formula I , II, III, or the like, and >=100,000, preferably, 300,000-500,000 average mol.wt. is incorporated in at least one layer formed above the subbing layer. As a result, a silver halide photosensitive material having good adhesion of an image, and excellent rubber erasability, and capable of forming an excellent wash-off-relief image is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a silver halide photographic light-sensitive material, and more specifically, a silver halide photographic light-sensitive material (hereinafter referred to as wash-off relief 5
What is the abbreviation?

Wash-off sensitive materials are developed using a tanning agent to harden only the exposed areas of the photosensitive layer. It is used to form a so-called "relief" image in which a portion of the surface is removed and the exposed portion remains in relief.

? It has the characteristic of being easy to perform. It can also be found in Eastman Kodak and DuPont catalogs. [Uni, i[! lI Tsukabe was easily erased with a wet 7c eraser.

However, one of the drawbacks of the photosensitive material is that it has a weak sexual desire. I heard that the sellotape was pasted on the drawing area, but the cellophane was too strong, and the second part of the drawing came off. Therefore, the bottom will improve the contact between both grasses! If you change it to 72/j, the Kushigom elimination will become worse in FEZ.

Therefore, the first objective of Motoaki is to provide a wash-off sensitive material that has good erasability with an eraser and good adhesion of images.

For the above purpose, an undercoat layer and a halogenated emulsion for tanning and tanning were placed on the support, and in this order, the following steps were taken: The fact that at least seven layers of 7'L'ic, which were provided above the undercoat 1G7, contained polymer latex allowed for delayed growth.

In addition to the silver halide emulsion layer, the polymer latex r@ layers include an anti-halation layer provided between the silver halide emulsion layer, an undercoat layer, and the silver halide emulsion layer, the 9 undercoat layers, and the antihalation layer. An intermediate layer (hydrophilic colloid, etc.) between the two? Preferably, the intermediate layer can include a polymeric latex to the antihalation layer.

The photographic milk used in the emulsion layer of the A-sensitized material of the present invention has at least 1 bicarbonate, a photosensitive silver halide, a water-visible retention colloid, and a tanning and development process. Silver halogenide emulsions are usually prepared by combining a water-bathable silver j
It is made by reacting a water bath-prone molecular solution such as seratin in the presence of a chemical. In addition to silver chloride and silver bromide, mixed halides such as chlorobromide,
Silver chloride, chloride, silver chloride, etc. can be used.

These silver halide grains can have any shape, such as cubic threads, octahedrons, or mixed crystal shapes. The particle size and average particle size distribution are not necessarily limited and may be of any value.

These silver halide grains are produced according to known and commonly used methods. Of course, it is also possible to use the so-called single Idl' full jet method, controlled double/jet method, etc. to make the M.

Alternatively, two or more types of silver halide 4 emulsions may be mixed together. These Yoma emulsions are based on "i'he Theory of Pbot" written by Mees.

Since X is decolorized by the development process V, there is no need to bathe it in a processing solution. Rather, it is possible for the artist to determine if any photosensitive resin remains in the antihalation layer in the exposed area even after the development process. Therefore, the light (absorbing material) in the antihalation layer is processed by ordinary black and white developing process such as carphone black or colloid film.
It is preferable for those who want to improve the concentration of the painting to have a color that is not bleached by the light and does not show off during the processing. 2.
