摘要： PURPOSE:To enhance a color forming speed and density, in thermal recording paper using a microcapsule showing permeability at the time of heating, by using oil having two or more of benzene rings and containing the specific number or less of hetero atoms as the core oil of the microcapsule. CONSTITUTION:As an org. solvent coming to core oil, a compound, wherein two or more of benzene rings are contained in the molecule thereof and the total number of hetero atoms of N, S, O and P are 1/10 or less of the total number of carbon atoms, is used. As this compound, a compound represented by each of formulae I-III [wherein R1, R3, R5 and R6 are hydrogen or an alkyl group, R2 and R4 are an alkyl group, p , q , p and q are 1-4, q is 1-3, (n) is 1 or 2 and (m) is 1-13] is designated. This org. solvent is used in an amount of 2-50pts.wt. of a leuco dye and, after both of them are emulsified, a wall comprising a high-molecular substance is formed around each oil droplet to obtain a microcapsule. This microcapsule is applied to a support along with the coupler and a binder.

摘要： PURPOSE:To prevent curling of a web support by coating the web support with a layer hardenable with electron beams on the side to be coated with emulsion layers, pressing a roll having a specified radius of curvature to the reverse side of the support with the coating layer outside to harden it in this roll-pressed state, and forming the emulsion layers on the convexly curved side. CONSTITUTION:A web support is coated with a compsn. contg. an unsatd. org. compd. polymerizable with electron beams and an inorg. white pigment on the side to be coated with emulsion layers, the support, with the coating layer outside, is pressed to a roll having a radius of curvature of 25-250cm, and exposed to irradiation of electron beams in this state. The convexly curved hardened face thus obtained is coated with the photographic emulsion layers. As said hardenable resin, fatty acid polyurethane acrylate, etc. are used, and as said inorg. white pigment, TiO2, etc. are used. When a photographic printing paper prepared by using such a electron beam hardened compsn. and forming emulsion layers on the convex face of said compsn. is exposed to a light negative image, developed, and dried, no curling is found on the web support. As a result, curling having a curling axis rectangular to the advance direction of the support web can be prevented.

摘要： PURPOSE:To improve fixability and electrostatic chargeability by using a mixture of microcapsules using hardenable materials as well as hardenable materials and hardeners as core materials as a capsule toner for pressure fixing and contg. a display recording material in one of these capsules. CONSTITUTION:Polyurethane acrylate, a polymn. accelerator, carbon black as well as magnetite and hexamethylene diisocyanate are compounded, and the compound is dispersed in a mixed solvent of acetone, hexane, etc. The soln. is added into an aq. soln. of gum arabic under vigorous stirring, whereby an emulsion of oil in water type is formed. Water at 40 deg.C is added to the emulsion to rise the temp. gradually to 90 deg.C and the emulsion is held for 20min under stirring, whereby microcapsules are formed. The capsule soln. is centrifugally separated to separate the gum arabic water, whereby powdery capsule toner is obtained. Thereafter, microcapsules of hardeners such as benzoyl peroxide are similarly obtaind. Two kinds of such powdery capsules are mixed, whereby the toner for pressure fixing is obtd.

摘要： PURPOSE:To obtain photographic resin-coated paper capable of obtaining images free from unevenness or glaring, by coating raw paper with a polyolefin layer containing TiO2 pigment particles coated with polyol on the surface, and patterning said layer with an embossing roll. CONSTITUTION:Raw paper is coated with a polyolefin containing TiO2 pigment and the surface of this layer is patterned with an embossing roll to produce photographic resin-coated paper. As this pigment, the surface of each particle of TiO2 is coated with a di- - tetra-valent polyol, such as ethylene glycol or trimethylol propane. The finely embossed pattern of the embossing roll surface is transferred in high fidelity, permitting a photographic resin-coated paper uniform in surface capable of obtaining an image free from partial glaring and unevenness to be formed by coating a photographic emulsion and preparing photographic paper.

摘要： PURPOSE:To obtain a medium which is suitable for laser recording of low energy and obviates unequal recording by joining a substrate and resin film under the pressure higher than the atmospheric pressure, then reducing the pressure to form a prescribed gaseous layer between both. CONSTITUTION:Hot-melt adhesive agents 16, 17 are coated on the substrate 11 and the resin film 12 is superposed thereon. The substrate and the film are then disposed between a heater block 26 in a pressurized vessel 19 and a receiving jig 21. Compressed air of 1.2-5atm is introduced into the vessel after the substrate 11 and the film 12 are joined by operating a thermocompression bonding machine 18, the substrate and film are taken out under the atmospheric pressure. The hermetic part between the substrate 11 and the film 12 is then expanded and the gaseous layer 34 is formed. This gaseous layer 34 constitutes the space for diffusion of the oxygen or evaporating gas necessary for combustion of the recording material at the time of forming bits. The medium suitable for a low-energy laser is thus obtd. and since there is no difference in the combustion evaporation, the medium which obviates the unequal recording is obtd.

摘要： PURPOSE:To contrive to reduce access time and to quicken a data rate by fixing a recording sheet medium onto a cylindrical drum, radiating light while rotating the cylindrical drum so as to write and read the information. CONSTITUTION:The recording sheet medium 3 is formed by a flexible base made of a material such as an acrylic resin and a recording layer capable of laser recording and/or reading on the flexible base. In fixing the recording medium 3 as above onto the cylinder 2, the cylinder 2 is driven by a driver 4. The recording medium 3 is subjected to radiation by an optical head 1 in this state to apply write/read of information. Thus, the data rate of recording/ reading is quickened and the access time is reduced.

摘要： PURPOSE:To provide excellent preservability, prevent head contamination from occurring and provide excellent thermal color forming properties, by incorporating a pigment having an average particle size larger than that of microcapsules into a thermal recording layer. CONSTITUTION:The thermal recording layer comprising microcapsules containing a color former and an organic solvent as core substances and a color developer is provided on a base. The walls of the microcapsules are formed of a material which is impermeable to both the color former and the color developer at room temperature, but when being heated, becomes permeable to at least one of the color former and the color developer, thereby providing a developed color image. In the thermal recording material, a pigment having an average particle size larger than that of the microcapsules is incorporated in the thermal recording layer. The pigment preferably has an oil absorption according to JIS-K-5101 of not less than 30ml/100g, and the amount thereof is 0.3-1pts.wt. per 1pts.wt. of the microcapsules.

摘要： PURPOSE: To prevent a recording material from being colored and obtain images with high developed color density and contrast, by incorporating at least one selected from 2-mercaptobenzothiazoles and thiurams into an organic solvent solution of a basic leuco dye contained in microcapsules.
CONSTITUTION: Among a group of compounds suitable for being incorporated in microcapsules together with a basic leuco dye, 2-mercaptobenzothiazoles and thiurams are highly effective. A highly stability can be obtained when a UV absorber is used together with the these compounds. Triarylmethane dyes having a phthalide structure and fluoran dyes are highly effective as basic leuco dye. Where the microcapsules are used for a pressure-sensitive thermal recording sheet, the microcapsules may be those obtained by an ordinary microencapsulating method. Where the microcapsules are used for a thermal recording sheet, it is necessary that micsrocapsule walls be opaque at normal temperature and become transparent when being heated. Among microencapsul ating methods, suitable are an internal polymerization method and an interfacial polymerization method.
