A thermosensitive recording material is a recording material with a structure in which a so-called thermosensitive coloring layer that develops color when heated is formed on a support such as paper, synthetic paper, or resin film, and has a built-in head for heating to develop the color. A thermal printer or the like is used. Compared to other recording materials, such recording materials can produce records in a relatively short time without complex processes such as development and fixing, do not generate noise, and are relatively inexpensive. Due to these advantages, it is useful not only for copying books and documents, but also for recording materials for various information and measuring instruments such as electronic computers, facsimiles, telex, medical measuring instruments, etc., as well as train tickets for station management systems, department stores, etc.
It is also widely used as a label for POS systems such as markets. Thermal recording type release paper allows printing and images to be recorded on the surface using a heating method, and after the recorded image has been formed, the release paper is peeled off from the release liner to which it has been temporarily attached, and then applied to the desired solid surface. Refers to sheets that can be glued together, such as number tags,
It is used for various labels such as price tags and medicine bottle tags, labels, name plates, stickers, etc.

The desired pattern was printed. However, in the case of heat-sensitive recording release paper, when printing with a thermal head, the ink print pattern comes into contact with the thermal head, making the head easily dirty.As a result, residue adheres to the head and the thermal printing area becomes dirty (tailing). etc.) occurred.

This invention eliminates staining of the thermal head and printing area due to the printed pattern, and prevents the printed pattern from bleeding due to the ink seeping into the support, and preventing the thermal coloring layer from smearing due to the ink seeping into the heat-sensitive coloring layer. An object of the present invention is to provide a heat-sensitive recording type release paper that does not develop any color (ground color).
