A method of forming a latent image portion on an overcoat layer by a difference in surface brilliance, at the time of layering an overcoat layer on a thermal transfer subject sheet by a heat transfer method, includes the steps of: setting at least two types of applied energy from the thermal head wherein a plurality of thermal elements are arrayed in line form, and layering the overcoat layer on the thermal transfer subject sheet; forming a difference in surface brilliance made up of a region of relatively high degree of brilliance and a region of relatively low degree of brilliance, based on the difference in the applied energy, to form a line pattern with a plurality of lines; and forming the lines by shifting a phase of a line pattern of the latent image portion and the line pattern of a background portion excluding the latent image portion.

An inkjet-recording medium has excellent various preservabilities, for example, the lightfastness of an image, resistance to bleeding under high-temperature and high-humidity conditions, and resistance to indoor fading and discoloration when a surface of a printing paper is subjected to laminating treatment. In an inkjet-recording medium having an ink-receiving layer on one surface of a base, the base having abilities to absorb and retain an ink solvent, a low oxygen-permeable resin layer preferably having an oxygen permeability of 10 cc/(m&#xb7;D&#xb7;atm) at a temperature of 20&#xb0; C. and at a relative humidity of 90% is provided on another surface of the base.

Ink jet recording medium, method of ink jet image formation and photographic print

An image is formed by thermally transferring dyes of a thermal transfer sheet onto a print recording medium, and then a protection layer is formed on the formed image. The transport speed of the print recording medium in the event of thermal transferring the dyes onto the print recording medium is set higher than that in the event of thermal transferring the protection layer onto the print recording medium. Thereby, the amount of thermal energy for application in the event of protection layer formation is increased to be greater than that in the event of image formation. Thereby, occurrence of concave-convex portions formed on the printed surface in association with a density difference in the event of image formation is prevented, and concurrently, the surface pattern in the event of image protection layer formation is improved.

A heat-sensitive transcription printer system is made up of a heat-sensitive transcription ink sheet cassette and a heat-sensitive transcription printing device on which said heat-sensitive transcription ink sheet cassette is loaded. On the heat-sensitive transcription ink sheet cassette is bonded an IC label having an IC memory a power receiving/supplying coil and a diode connected to the IC memory and a signal communication coil for performing communication of signals between the IC memory and the heat-sensitive transcription printing device. The inherent discrimination information is previously recorded on the heat-sensitive transcription ink sheet cassette and can be read out from it electrically. In this heat-sensitive transcription printing device the driving power is supplied from a power supply unit through a power supply coil power receiving/supplying coil and the diode to the IC memory A system controller reads out the discrimination information and the using hysteresis information from the IC memory through the signal communication coils to control the printing operation.

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.
