More specifically, in the present invention, the heat-sensitive transfer layer on the support forms a sponge-like structure, and the solid ink is contained inside the sponge-like structure, and the solid ink is contained inside the sponge-like structure by the thermal energy of the heat-sensitive head. The present invention relates to a thermal transfer material in which ink can be melted and oozed out onto the thermal transfer material for transfer.

の変化に乏しいという欠点があつた。(b) Prior Art and Problems Conventionally, technologies related to this type of heat-sensitive transfer material are already known. In this conventional thermal transfer material, the resin forms a sponge-like structure, and solid ink is contained inside this sponge-like structure, so that the ink in the thermal transfer layer is not transferred all at once by the thermal energy of the thermal head. By oozing out gradually and transferring to plain paper, it is possible to record multiple times on the thermal transfer material, and it is now a one-time thermal transfer medium in which the thermal transfer layer, which is a mixture of wax and pigment, is applied directly to the support. It has remarkable advantages. However, when this thermal transfer material simply uses wax as a colorant medium for the ink contained inside the sponge-like interior, even if the solid ink is melted by the thermal energy of the thermal head, it does not bleed onto the thermal transfer material. Furthermore, ink that uses waxes in combination with dispersants such as sorbitan sesquioleate and pentaerythritol stearate does not improve ink bleeding (see comparative example), and is therefore used for multiple recording applications. In some cases, the recording density was low and the transferred recording lacked sharpness. In addition, when used for density gradation recording, there was a drawback that there was little change in density gradation.

ある。(d) Structure of the Invention That is, the present invention involves mixing a pigment coloring agent into a coloring medium consisting of an oil-soluble sulfonic acid metal salt and waxes, and dispersing this mixture in a solution of a resin dissolved in a volatile solvent. This is a heat-sensitive transfer material obtained by coating a support with this material and then drying it by evaporating a volatile solvent.

オネートと合成スルフオネートに大別される。 One feature of the present invention is the use of an oil-based sulfonic acid metal salt having a molecular weight of 400 or more. This oil-soluble sulfonic acid metal salt is called a sulfonate, and is roughly classified into petroleum sulfonate and synthetic sulfonate depending on the raw material.

れる。 Thus, when an oil-soluble metal sulfonate is included in the colorant medium, satisfactory ink bleed onto the thermal transfer material is achieved, but this is because oil-soluble metal sulfonates are strongly ionic. The base-
It is believed that by having SO 3 M, the pigment is adsorbed to the pigment and stably dispersed in the wax, so the pigment does not migrate into the resin film but oozes out with the wax when heated, resulting in good recording. Ru.
