となどから、この分野では急速に発達している。(Prior art) Thermosensitive recording is a general term for anything that utilizes physical or chemical changes caused by heat.Recently, a combination of an electron-donating colorless dye and an electron-accepting compound has been used to improve color sensitivity and color development. It has come to be widely used because it is relatively excellent in terms of density, storage stability before color development, and color fastness. (For details, see Tokuko Showa 4Lj-1i+p, Tokuko Showa 4'4'

1-34-! r7μ, etc.) These heat-sensitive materials are heated and recorded by heat in, laser light, side radiation heat, etc., but a so-called thermal head, in which a plurality of heating elements are arranged on a base material, is used. It is often used. (For details, see JP-A-6-11R137, JP-A-1L-
tJOj2, Tokukai Sho! Thermal printers and thermal facsimile machines are well known as recording methods using the above-mentioned heat-sensitive materials and thermal heads, and these use heat-sensitive materials other than heat-sensitive paper. This field is rapidly developing because it requires no consumables, is maintenance-free, and has low costs for equipment and recording paper.

。As described above, heat-sensitive recording used in a thermal head has various advantages, but there are still problems that need to be solved. One of them is dirt on the thermal head. A typical thermosensitive recording paper is made of an electron-donating colorless dye and an electron-accepting compound, as described above. As the electron-donating colorless dye, triphenylmethane-based leuco dyes, fluoran-based leuco dyes, etc. are used.

はいえない。Further, as electron-accepting compounds, phenol derivatives, aromatic carboxylic acids, etc. are generally used. These are fused by heating with a thermal head or the like, and react and develop color. At this time, a part of the melted thermosensitive coloring component is transferred to the thermal head side and becomes a stain. If this stain is small, it will not pose a major problem in printing, but if it is significant, it will cause a decrease in print density or the occurrence of unprinted areas, which greatly impairs the maintenance-free advantage of thermal recording. Countermeasures against these problems have been proposed, such as adding highly oil-absorbing pigments to the thermal paper side or adding various additives (Tokukosho! Ir-JJ

3!174, Japanese Unexamined Patent Application Publication No. 2003-317031, Jpn. Pat. Appln. KOKAI Publication No. 2003-317317, R2J23, etc.), these methods cannot be said to be advantageous because they involve a decrease in sensitivity and an increase in cost.
