本発明は、熱印加による転写記録に用いられる感熱記録
用転写体に関し、特に色材に昇華性染料を用いる高熱エ
ネルギー記録に有効な転写体に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a transfer body for heat-sensitive recording used for transfer recording by heat application, and particularly to a transfer body effective for high thermal energy recording using sublimable dye as a coloring material. It is.

添加しているが、濃度低下が起こる欠点があった。Conventional Structures and Problems Full-color transfer bodies containing sublimable dyes have been widely studied. However, images recorded using these transfer materials have problems with disturbances in halftone areas due to recording dropouts in areas where energy is applied and dye sublimation or scattering (noise) in areas where energy is not applied. ing. In order to prevent this, particles of 0.1 to 1000 μm are added, but this has the drawback of causing a decrease in concentration.

防止することができる。Structure of the Invention In the thermal recording transfer material of the present invention, the coloring material layer provided on the surface of the substrate comprises a sublimable dye, ultrafine particles having a single particle average particle size of 0.1 μm or less, and a binder that binds them together. It is composed of Here, the coloring material layer contains ultrafine particles with a single particle average diameter of 0.1 μm or less, which makes the surface of the coloring material layer ultrafinely roughened and makes the thermal conductivity uniform. Ru. As a result, uneven transfer due to melting of the sublimable dye and contact with the image receptor is drastically reduced, and the heat applied to the transfer body is uniformly conducted to the sublimable dye through the ultrafine particles.
Homogeneous sublimation of the sublimable dye is promoted, and a decrease in recording density can be prevented.

合、均一に分散されるので有効である。Synthetic amorphous silica, alumina, titanium oxide, and silicic acid compounds are most likely to be used as the material having an average particle diameter of 0.1 μm or less. In particular, ultrafine particles produced by a vapor phase method have a more uniform particle size than pulverized particles, and are therefore effective when added to a coloring material layer because they are uniformly dispersed.

イザー等によりよく分散される。The ultrafine particles were produced by a gas phase method. Examples of products produced by the gas phase method include high-purity ultrafine particulate silica, aluminum oxide, and ultrafine titanium oxide particles sold under the name Nippon Aero's Rysil (Co., Ltd. 7 Erosil), which have a weight ratio of 10-1 to the binder. It can be used in the range of ~102.This is because if the weight ratio is less than 10, it is impossible to uniformly roughen the surface quantitatively, and if it is more than 10, the particle size of the coating liquid increases and it is impossible to roughen the surface uniformly. This is because the effect is particularly great when the ratio to the binder is in the range of 1 to 30. Ultrafine particles are well dispersed by ultrasonic waves, a ball mill, a homogenizer, etc.
