Title: Thermal transfer material
Inventor: SUGANO NOBUMORI
IPC: B41M5/382
Filed: 1987-05-29
Abstract: PURPOSE:To obtain a thermal transfer material capable of giving a high transferred density even in multi-time transfer, by causing a transfer control layer for an ink layer to comprise particulates of a low melting point resin and a high molecular weight substance having a melting point higher than that of the particulates. CONSTITUTION:This thermal transfer material comprises a heatfusible ink layer 2 and a transfer control layer 3 on a base film 1. The transfer control layer 3 is obtained by applying a coating liquid obtained by mixing particulates 4 of a low melting point resin with a solution of a high molecular weight substance 5 which is incompatible with the resin particulates and has a melting point higher than that of the resin particulates. If the viscosity of the solution of the high molecular weight substance is too high, it is difficult to pulverize the low melting point resin. It is preferable that the thickness of the film of the high molecular weight substance is smaller than the thickness of the ink layer. By this, a thermal transfer material can be obtained which shows little decrease in transferred density with the number of times of use thereof, is capable of printing with low energy, has a high sensitivity, and is capable of transferring high-density images with excellent resolution.
