Thermal dye transfer image-receiving sheet.

摘要

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.
