摘要： PURPOSE:To improve photosensitive characteristics by using an ionic-paired ion compd. to form the photopolymn. initiator of a photosensitive layer contg. a photosensitive silver halide, org. silver salt, reducing agent, and polymerizable polymer precursor. CONSTITUTION:The photopolymn. initiator of the photosensitive body contg. all of the photosensitive silver halide, org. silver salt. reducing agent and polymerizable polymer precursor is formed of the ionic dye-paired ion compd. The photosensitive silver halide is exemplified by silver chloride, silver bromide, silver chlorobromide, silver iodobromide, silver chloroiodobromide, etc. Silver salts having low photosensitiveness, such as org. acid silver and triazole silver salt are preferably used as the org. silver salt. A primary color developing agent and secondary color developing agent are usable as the reducing agent. Cationic dyes having boron anions are used as the photopolymn. initiator. Compds, having at least one piece of reactive vinyl groups in one molecule are utilizable as the polymerizable polymer precursor. The images having the excellent lightness and saturation are sufficiently formed by a light source of low electric power consumption.

摘要： PURPOSE:To easily form an image of high picture quality with an excellent contrast by putting the image forming medium where a latent image is formed and an image receiving body one over the other and heating them under a specific condition, and transferring a heat-diffusing material to the image receiving body and forming an image. CONSTITUTION:The image forming medium is constituted by forming a coloring material layer 2 which contains the heat diffusing material and a polymerizing layer 1 which contains a polymerizing compound and a polymerization initiator on a base 3. Then the polymerizing layer 1 is exposed through a proper negative mask 4 to polymerize the polymerizing compound in the polymerized layer 1, thereby forming the latent image consisting of a polymerized part 1-a and an unpolymerized part 1-b. Then the image formed medium where the latent image is formed and the image receiving layer 6 on a base body 5 are put one over the other and heated under the heating condition shown in an expression I to diffuse and transfer the heat diffusing material that the image formed medium contains to the image receiving layer 6 through the polymerized layer 1. In the expression I, Ttrans shows the temperature of the image forming medium, Tg1 the glass dislocation temperature of the unpolymerized part 1b, and Tg2 the glass dislocation temperature of the polymerized part 1g. Consequently, the excellent image which has high contrast and no fogging is obtained.

摘要： PURPOSE:To attain a recording with semiconductor laser beam and to obtain a stable image of high-definition by incorporating a semiconductor laser photosensitive photopol ymerization sensitizer, a polymerization initiator, a reactive binder and a thermal diffusion type dyestuff. CONSTITUTION:As the sensitizer acting efficiently at >= 600 nm of wavelength light and incorporating as a cation dye structure, for example, a polymethylene system dye, is used, it has a wider width of an absorbing peak, and it can easily correspond to the variation of the wave length due to a temp. of the semiconductor laser and the variation of the wavelength due to the variations between the lots. The polymeriza tion initiator is a radical generated from the polymerization, for example, an amine compound is used. Next the reactive binder is preferably a high polymer compound having a polymerized unsaturated double bond, for example, an acryl group, etc. The thermal diffusion type dyestuff is an azo type dispersion dye, etc., which diffuses thermally or sublimes thermally with heating at 90-200 deg.C. When exposed with the laser beam, an exposed part is hardened and next an image receiving body 10 is confronted with a protective layer 4 or is laminated with a polymerized layer 3 after the protective layer is stripped, then heated. Thus, the desired pigment image 12 is obtained.

摘要： PURPOSE:To easily hold the secrecy of the communication content outputted to recording paper from communication machinery by providing an adhesive layer composed of a hot melt type adhesive or a pressure type adhesive to the non-recording part of a recording surface and further providing optical markers for reading perforations and/or the adhesive layer. CONSTITUTION:The first perforations 3 for holding and the second perforations 2 for opening are formed to recording layer 9 and an adhesive is applied to the non-recording parts present on both side parts of the recording paper 9 to form adhesive layers 1. The perforations 2 may not be provided on both sides of the recording paper but on the single side thereof. The shapes of the perforations 2, 3 are not especially limited and may be same or different mutually. Further, optical markers 5 for reading recordable parts and the positions of the perforations are provided. Therefore, by concealing recording content by bonding the recording papers by the adhesive at the time of recording or after recording, a secret can be kept.

摘要： PURPOSE:To rapidly obtain a stable image by forming a high-contrast polymer latent image with a photosensitive body contg. photosensitive silver halide, an org. silver salt, a reducing agent, a polymerizable precursor of a polymer, a photopolymn. initiator and a thermally diffusible dyestuff. CONSTITUTION:A photosensitive body contg. photosensitive silver halide, an org. silver salt, a reducing agent, a polymerizable precursor of a polymer, a photopolymn. initiator and a thermally diffusible dyestuff is imagewise exposed with light, e.g. in the wavelength range of 400-900nm to generate silver nuclei and the org. silver salt is reduced with the reducing agent by the catalytic action of the silver nuclei by heating to about 60-180 deg.C. The reducing agent is oxidized by oxidation-reduction reaction at the time of the heating to form a distribution of the reducing agent and the oxidized body different from each other in polymn. inhibiting ability to the polymerizable precursor. The photosensitive body is then uniformly exposed with light in a specified wavelength range. By this exposure, the polymerizable precursor is selectively polymerized according to the distribution and a polymer latent image composed of polymerized and unpolymerized parts is formed. The photosensitive body has a photosensitive layer 2 on the substrate 1 and a protective layer 3 may be formed on the layer 2.

摘要： PURPOSE:To increase the contrast of ploymerized images by heating the photosensitive body to a prescribed temp. simultaneously with or after image exposing to form silver and/or the oxide of the reducing agent in image unexposed parts, then exposing the entire surface thereof. CONSTITUTION:The photosensitive body is constituted by laminating a polymn. layer 2 contg. a polymerizable polymer precursor and a photoplymn. initiator on, for example, a supporting body 3 and a photosensitive layer 1 contg. a photosensitive silver halide, org. silver salt, the reducing agent. The photosensitive body is heated to the temp. at which thermal fogging arises or above simultaneously with or after the image exposing to form the silver and/or the oxide of the reducing agent in the image unexposed parts without forming the same in exposed parts 4. The entire surface is then exposed to form the polymerized images in the exposed parts 4. The polymerized images 6 are taken out by an etching treatment or peel-apart. A hindered phenol compd. is preferably used for the reducing agent.
