Abstract: A novel display material is disclosed, which comprises a material layer containing a dye and a supporting electrolyte. The material layer is capable of solid-liquid transformation. The coloration and discoloration of the layer are effected by oxidation reduction reaction of the dye by applying current to the material layer in liquefied state. The display material may be used as electrochromic display and thermosensitive recording paper.

Abstract: The photographic paper (210) is intended for use with a printer with which a vaporisable dye from the latter is absorbed on a receptor layer (211) provided as an upper layer of a photographic paper base. A light absorbing layer (212) formed by a light absorbing agent is provided between the photographic paper base and the receptor layer. The light absorbing can be whitened in colour hue by thermal defraction either of the light absorbing agent itself by a light radiating element of the associated printer, or of a capsule enclosing a whitening agent mixed with the light absorbing layer.

Abstract: A printing apparatus in which metered amounts of an ink and a diluting solution are mixed and the resulting mixed liquid is ejected to a recording medium for printing. Specifically, the ink and the dilution liquid at least containing a water-soluble organic solvent are mixed together in respective metered amounts and the resulting liquid mixture is ejected to the recording medium. The water-soluble organic solvent desirably contains the aliphatic monohydric alcohol, a polyhydric alcohol or its derivatives. The dilution liquid may contain a non-water-soluble organic solvent or a dispersion medium composed of water and a non-water-soluble resin. An OH-group containing resin and a cross-linking agent are desirably contained in the non-water-soluble resin. Ink fixing properties for a picture recorded by discharging the liquid mixture of the ink and the dilution liquid may be improved, while suppression of bleeding in the picture and improved discharging stability are also achieved.

Abstract: A sheet of the type which comprises a release base sheet and a thermal transfer image-receiving layer formed on the release base sheet and which is capable of releasing the thermal transfer image-receiving layer from the base sheet is described. The receiving layer is made of a dispersion, in a resin binder, of a layer compound capable of fixing cationic dyes through ion exchange reaction therewith. The receiving layer can be readily formed on a desired type of substrate by superposing the receiving layer on the substrate, after which the release base sheet is peeled off from the receiving layer. A thermal transfer image can be formed on the receiving layer by superposition with an ink ribbon containing a cationic dye and application of image information to the ink ribbon or by re-transfer of a cationic dye image from a printing paper. The thermal transfer image may be formed prior to the transfer of the receiving layer on the substrate. Owing to the fixing of the cationic dye through ion exchange reaction, the fixing properties of the dye in the receiving layer can be significantly improved.

Abstract: A method for forming images by a thermal transfer process. The method comprises the steps of providing a printing sheet having an image-receiving layer on one side thereof, providing an ink ribbon having a dye layer comprising a hydrophilic cationic dye, contacting the ink ribbon with the image-receiving layer, and applying a thermal energy to the ink ribbon in an imagewise pattern to thermally transfer the dye from the ink ribbon to the image-receiving layer. The image-receiving layer comprises at least a layer compound which has ion exchangeability with the cationic dye, so that the dye image is fixed through the ion exchange. Since the dye is bonded to the layer compound through ion exchange, the dye is fixed comparable to that of silver salt photography. A thermal transfer system using the ink ribbon and the printing sheet is also described.

Abstract: PCT No. PCT/JP83/00107 Sec. 371 Date Nov. 29, 1983 Sec. 102(e) Date Nov. 29, 1983 PCT Filed Apr. 7, 1983 PCT Pub. No. WO83/03687 PCT Pub. Date Oct. 27, 1983.A photosensitive imaging material utilizing changes in adhesive properties due to light, wherein an alloxazin derivative represented by the general formula: [wherein R's may be the same or different from each other and each represents an alkyl group having 1 to 20 carbon atoms or a phenylalkyl group represented by the formula: (wherein n is an integer of 1 or more)] is used as a photopolymerization initiator, thereby enhancing the photographic speed and photographic sensitivity of the photosensitive material. Further, in order that the photosensitive material can possess image halftone reproducibility per se, the photosensitive material may be made into a composite material in which a photosensitive layer additionally containing a tertiary amine as a sensitizer is laminated on a hardened layer formed by hardening a photosensitive composition. The photosensitive imaging material of this invention thus constructed can be employed as a copying material for recording or reproducing projected images from a cathode ray tube or a fiber tube.

Abstract: In a recording medium for a printer having a dye fixation layer mainly composed of an interlayer compound for receiving and holding a water-soluble dye by an intercalation reaction, and a binder, the ink is to be improved in ink absorption, fixation, water-proofness and bleeding characteristics to enable image formation to a high resolution. A dye fixation layer 3, mainly composed of an interlayer compound for fixing and holding the water-soluble dye by the intercalation reaction derived from the ion exchange action and the binder is formed as an outermost layer on a substrate 2. The binder of the dye fixation layer 3 contains the urethanated polyvinyl alcohol resin having an urethanation ratio of 1 to 20 mol%.
