As can be seen from the above scheme, the assumption about the nature of the destruction of the dye molecule is based on the possibility of the formation of a colorless dye-base, free radicals J and CH3O. and aldehyde CHzO.

When eergo-sensitive compounds are exposed to such energy, they undergo some changes, which consist, as a rule, in the destruction of the dye molecule. In each individual case, the nature of the destruction depends mainly on the structure of the original dye. However, it can be assumed that one of the most likely ways of destruction of the dye molecule during irradiation is as follows:

The energy-sensitive layer can be applied to any substrate, and it can not only be applied to the surface of the substrate, but also impregnate the entire sub-spoon with a dye solution. It is desirable to use substrates with low thermal conductivity. As a substrate for heat-sensitive compositions, as a rule, ordinary paper can be used, and 15 this paper can be transparent, translucent and opaque. Especially often used substrates that have the ability to transmit (pass) radiation. This is desirable, for example, in those cases where the original being copied does not transmit such radiation (at least, either the substrate or the original must transmit the exposure radiation). Therefore, it is advantageous to use paper or 25 other fibrous materials with carbonation temperatures above 125 ° C as substrates. In the preparation of thermographic materials, a heat-sensitive dye is applied, usually on a translucent or completely non-30 transparent substrate. After the present, the heat-sensitive copy sheet is then brought into contact with the original containing any text, drawing, graphic, drawing that needs to be copied (for example, 35 text printed on a typewriter) and exposed using infrared radiation. Those parts of the original that are highly absorbent with respect to infrared radiation transform this energy into heat, which is transferred to the copier due to thermal conductivity, causing a rapid change in color in those areas of the sheet that receive heat45 from the original. In other words, the color of the copy sheet changes in places that, when a copy sheet is laid on the original and close contact between them, correspond to the most heated sections of the original, i.e., those that absorb infrared radiation. Those parts of the copy sheet that do not accept heat from the original, transmit infrared radiation or reflect it in such a way that the color change of the copy material does not occur in these places. If necessary, heat-sensitive soy-60 dinenees can be dispersed in the binder and the composition thus obtained is applied to the surface of the substrate. Tin, collodion, polyvinyl acetal, cellulose ethers and hydrolyzed cellulose. Eperfectuous materials should be used as photographic materials to obtain a photo image by exposing such materials to light, detached from the object being photographed. At the same time, positive reproduction is immediately obtained. Among the advantages of such a photographic process, which has a number of advantages as compared to conventional processes, is the denial of the manifestation of a photographic image and its application to obtain a "covering composition (panosima on the surface of the substrate) of any other materials except an energy-sensitive dye. Since such dyes have different colors, you can get a color photo image. In order for energy-sensitive dyes to be more conveniently applied to the substrate, they are best dispersed in the film-forming binder. If the layers to be used in accordance with the present invention contain gelatin, they may also contain tanning agents. Since the colorants provided are of a different initial color, they can be used to produce direct positive color prints, i.e., using compositions with a specific combination of dyes of different colors and different photosensitivity, it is possible to simplify the usual color photographic process and immediately after shooting get color positive photo reproductions of the original. Thus, if a layer of yellow dye is first applied to the white substrate, then a layer of magenta and cyan dye is applied on top of it, and the material thus obtained is exposed to visible light transmitted through the color film, a direct positive color photoprint is obtained. Three dyes need not be present in such material as separate layers; they can be applied to the substrate in the form of a homogeneous mixture. A color image is obtained on such a photographic material due to the fact that each of the dyes that make up the material is discolored when the material is exposed to light only under the action: 1 light with the wavelength it absorbs. Energy-sensitive materials can contain at least one photographic halogen-silver emulsion layer. In such a material, the energy-sensitive dye can act as an anti-. voorele or filter layer. In this case, the dyes can be etched n, directly in the layer deposited on the substrate and in contact with the photosensitive halide-silver emulsion stability at a pH characteristic of the most sensitive halogen-sulfur emulsions and, moreover, they do not have a similar pattern. silver or it is a crimped unkind. Dyes can also be used as filter dyes in layers applied directly onto a photosensitive halide-silver emulsion layer or between two halide-silver emulsion layers. The dyes can also be used in layers deposited between the substrate and the photosensitive halide-silver emulsion layer, or in layers deposited on the back side of the substrate as the irothynorol layer. Materials in which the dyes are used in the flashing layers may contain either conventional halogen-silver-emulsion emulsion, in a manner customary), or light-soluble halogen-inode-emulsion emulsion described in U.S. Pat. No. 3,418,122 n Cd 3447927.

Filter elephants can be applied by applying to a photographic material,: - or its backing is well-established using methods such as a dye solution, using hydrophilic colloidal binding, it and various wetting agents, such as saponin. In addition to these materials, it is advisable to add to the solution containing the dye, nro-grass, in order to make this dye stable and harmless to other substances that make up the photographic material, in particular, to the silver halide. For most purposes, it is desirable to add tannins to the hydrophilic colloidal binder. The RP of the solution intended for applying the filter layer is adjusted to a level compatible with the pH of the photosensitive emulsion layer.

The described lining layer can be made in the form of a layer capable of absorbing the blue part of visible light; Such a layer can be used in conventional three-layer color photographic materials, characterized in that an emulsion elephant is applied to the backing, sensitive to the red, green, and sniepas of visible light. A filter layer capable of absorbing blue light may be located between the light-transmitting flame-emulsion layer: and, respectively, sensitive to c1P1 and part of the spectrum.

Example 1. A thermographic material is produced by applying a composition containing gelatin and a redder onto a buried substrate. A graphic original containing text printed on a maskinch is arranged in such a way that it is brought into close contact over the entire area with the reverse side of the paper, i.e. The side on which the composition is not applied. Then the folded sheets of the original are pressed together and
