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: PURPOSE:To improve sensitivity at the time of transfer and the hue and light fastness of an obtained image by making it possible to use a cation dye incapable of being used heretofore as an image forming material in a thermal transfer system. CONSTITUTION:The pair ion such as halogen of a hydrophilic cation dye is exchanged with an org. anion such as a sulfosuccinic acid anion, for example, a diethylhexylsulfosuccinic acid anion, an alkylbenzene sulfonic acid anion, for example, a dodecylbenzenesulfonic acid anion or an alkylsufuric acid anion, for example, a laurylsulfuric acid anion or a soap anion to make the cation dye hydrophobic. An ink layer 3 containing this cation dye made hydrophobia is laminated on a support 2 having a heat-resistant slip layer 1 to obtain a thermal transfer ink ribbon 10.

Abstract: PURPOSE:To protect the data preliminarily written on a card base material directly in cards such as an ID card or the like and to form a dye image having high fixing properties equivalent to a silver salt photograph on the surface of the card base material by a sublimation thermal transfer recording method. CONSTITUTION:A receiving layer 2 wherein an interlaminar compd. capable of fixing and holding a cationic dye by ion exchange reaction is dispersed in a resin binder is formed on at least the single surface of a card base material 1 pref. in a thickness of 2-10mum. A transparent resin layer may be formed on at least the single surface of the card base material 1 and the transparent resin layer and the receiving layer may be successively laminated on the card base material 1.

Abstract: PURPOSE:To decrease a required quantity of a reaction medium and an onium salt, to improve yield and to reduce reaction time at the time of obtaining a cation exchanger of an intercalation compd. by the use of an onium salt slightly soluble or insoluble in water. CONSTITUTION:In a method for producing the cation exchanger of the intercalation compd. by cation exchanging an exchangeable cation of the intercalation compd. having the exchangeable cation in the interlayer with the onium salt, the intercalation compd. and the onium salt are dispersed in a nonaqueous solvent and the dispersed solution is mixed with a high dielectric solvent hardly dissolving the onium salt and having excellent swelling property for the intercalation compd. In this case, a quaternary ammonium salt, phosphonium salt and a cation dye which are slightly soluble or insoluble in water are used as the onium salt and a montmorillonite group is used as the intercalation compd.

Abstract: PURPOSE: To improve greatly fixing property and durability of an image to be formed by sublimation type heat transfer recording at the time of performance of the sublimation type heat transfer recording and hot-melt type heat transfer recording with one ribbon. CONSTITUTION: A heat transfer ribbon IA is constituted by providing a sublimation ink layer 3 which is an ink layer containing sublimation or heat dispersion dyes and the dyes are transferred to a transferred body from the ink layer by heating, a hot-melt transfer ink layer 4 comprised of hot-melt ink which is molten and transferred to the transferred body through heating and a heat transfer laminated layer 5 which is molten and transferred to the transferred body through heating. Cationic dyes which are made into a hydrophobic state is caused to be contained into the sublimating ink layer 3 and an interlaminar compound which can fix and hold the cation which is made into the hydrophobic state is caused to be contained into the heat transfer laminated layer 5.
