DESCRIPTION OF THE PREFERRED EMBODIMENTS A thermosensitive recording label can be constituted by forming a reversible thermosensitive recording material layer on a substrate. The reversible thermosensitive recording material constituting the reversible thermosensitive recording material layer is, for example, a material obtained by dispersing an organic low-molecular substance in a polymer resin base material. In addition, when the temperature region T2 higher than the temperature region T1 is reversibly changed to an opaque (opaque) state by cooling to room temperature, when the temperature region T3 is cooled to room temperature, the opaque (opaque) state is formed. T3
It is reversibly changed to a transparent state by cooling to a normal temperature from a higher temperature region T4, but after being processed to a temperature region T5, a transparent state and an opaque (opaque) state are reversibly changed by controlling a cooling rate. And those that reversibly change between a colored state and a decolored state depending on the heating conditions.

The reversible thermosensitive recording material can exhibit two types of visible image patterns, that is, a transparent background / opaque print pattern (positive type) and a cloudy background / transparent print pattern (negative type). In the case of (1), positive recording can be performed by making the sheet transparent at the low temperature T1 and giving the high temperature T2 to print, and in the case of (2), it becomes cloudy at the low temperature T3 and printing by giving the high temperature T4 to perform negative recording.

In the method, a negative-type recording can be performed by slow cooling erasure / rapid cooling printing, utilizing the property of being transparent by rapid cooling and becoming opaque (cloudy) by slow cooling. Are mainly composed of a polymer resin base material and an electron-donating color-forming compound and an electron-accepting compound dispersed in the polymer resin base material. Image patterns are possible.

The above-mentioned reversible thermosensitive recording material can be printed by utilizing non-contact heat conversion of a laser beam. Also,
Erasing can be performed by blowing hot air or heating with an infrared heater.

As the substrate on which the reversible thermosensitive recording material layer is formed, PET, polycarbonate, polypropylene, and other plastic films or sheets having good heat resistance are preferred. The thickness of the substrate is 10 to 500 μm, preferably 50 to 250 μm. A reflective layer, a reversible thermosensitive recording material layer, and a protective layer can be sequentially laminated on the surface of such a base material by a known method to form a thermosensitive recording label. The total thickness of the thermal recording label is usually 20 to
It is 550 μm, preferably about 60 to 300 μm.

The reflective layer is for making the information formed on the reversible thermosensitive recording material layer easy to see, and is preferably made of aluminum, tin, or the like, or foil. Instead of the reflective layer, the surface of the base material can be colored by printing or the like, and information can be displayed so that the underlying color is transparent. An air layer may be provided between the base material and the reversible thermosensitive recording material layer to improve the contrast.

As the polymer resin base material constituting the reversible thermosensitive recording material, a synthetic resin which is transparent and has good film-forming properties, for example, polyvinyl chloride and its copolymer (vinyl chloride-vinyl acetate copolymer, etc.) ), Polyvinylidene chloride and its copolymer, and other known resin base materials.

As the organic low-molecular substance dispersed in the polymer resin base material, known substances such as higher fatty acids, higher dicarboxylic acids, higher fatty acid esters, higher ketones, higher ethers, higher alcohols and derivatives thereof can be mentioned. In order to widen the transparent temperature range, those having different melting points can be mixed and used. The thickness of the reversible thermosensitive recording material layer is usually 3 to 20 μm.

As the protective layer, a transparent film or coating having high heat resistance such as PET, polyetherimide, polyacrylate, polycarbonate, acrylic resin, etc. can be used.
