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:
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.
Abstract:
A developing paper having an image receiving dye layer containing a plasticizing agent on a substrate, the plasticizing agent including a solid plasticizing agent which is solid in the application temperature and a liquid plasticizing agent which is liquid in the application temperature. Since the developing paper contains a plasticizing agent including a liquid plasticizing agent and a solid plasticizing agent, the developing paper has an excellent light resistance. Moreover, since the plasticizing agent contains a liquid plasticizing agent and a solid plasticizing agent, there is no danger of precipitation of the plasticizing agent from the surface of the developing paper. Furthermore, the developing paper containing the aforementioned plasticizing agent enables to obtain a desirable plasticizing effect.
Abstract:
A heat-sensitive transcription printer system (100) is made up of a heat-sensitive transcription ink sheet cassette (10) and a heat-sensitive transcription printing device (50) on which said heat-sensitive transcription ink sheet cassette is loaded. On the heat-sensitive transcription ink sheet cassette is bonded an IC label (20) having an IC memory (21), a power receiving/supplying coil (23) and a diode (24) connected to the IC memory (21) and a signal communication coil (22) for performing communication of signals between the IC memory (21) and the heat-sensitive transcription printing device. The inherent discrimination information is previously recorded on the heat-sensitive transcription ink sheet cassette (10) and can be read out from it electrically. In this heat-sensitive transcription printing device (50), the driving power is supplied from a power supply unit (55) through a power supply coil (61), power receiving/supplying coil (23) and the diode (24) to the IC memory (21). A system controller (51) reads out the discrimination information and the using hysteresis information from the IC memory (21) through the signal communication coils (22, 56) to control the printing operation.

Abstract:
PROBLEM TO BE SOLVED: To prevent a scratch on an acceptance layer from being caused by inhibiting the frictional contact of the front and back faces of a recording web wound in the form of a roll with each other. SOLUTION: The recording web 2 wound in the form of a roll stored freely rotatably in a paper supply cassette 1a includes the acceptance layer 3c which receives a dye of dye layers 33b to 33e, formed on the face of the recording web 2 and a back layer 3d for controlling a friction with the acceptance layer 3c during winding the recording web 2, formed on the back. In addition, the coefficient of dynamic friction between the acceptance layer 3c and the back layer 3d is set to be not less than 0.10 and thus the looseness of the recording web 2 during unwinding the web 2 is inhibited. Also, the acceptance layer 3 can be made chafe-proof. COPYRIGHT: (C)2007,JPO&INPIT

PROBLEM TO BE SOLVED: To make a cationic dye, which can not conventionally be used as an image-forming material in a heat transfer method, usable and to thereby improve sensitivity in transfer, hue and light resistance of obtained image. SOLUTION: This cationic dye is provided with hydrophobicity by exchanging counter ion such as a halogen, etc., of a hydrophilic cationic dye with a sulfosuccinic acid anion such as diethylhexylhexylsulfosuccinic acid anion, an alkylbenzenesulfosuccinic acid anion such as dodecylbenzenesulfosuccinic acid anion, an alkylsulfuric acid such as laurylsulfuric acid anion or an organic anion such as soap anion. An ink layer 3 containing the hydrophobilized cationic dye is laminated to a substrate 2 having a heat-resistant sliding layer 1 to give a heat transfer ink ribbon 10.
