れていない。[Prior Art] Various types of heat-sensitive recording materials have been announced so far that utilize a heat-coloring reaction between at least one colorless or light-colored basic dye and phenols, organic acids, etc.
-14039, etc.) have been widely put into practical use. These heat-sensitive recording materials are applied to a wide range of fields such as measuring recorders, computers, information terminals, facsimile machines, automatic ticket vending machines, and CD/ATMs. These recording devices are equipped with a thermal element such as a thermal head or a thermal pen, and by heating this element, color can be generated and a recording can be obtained. Recently, applications have become more diversified and equipment has become more sophisticated, and along with this, the quality required for heat-sensitive recording materials has also become more sophisticated. For example, what used to take several minutes to record an A4 size fax using a facsimile can now be done in less than one minute. Under these circumstances, the addition of sensitizers has been proposed as a method to improve the sensitivity of thermal recording paper, but the color development sensitivity,
A material that satisfies the various performances required of a heat-sensitive recording material in a well-balanced manner, such as stability of colored images and recording suitability, has not yet been obtained.

。Examples of adhesives used in thermal recording paper in which the above-mentioned color-forming substance and phenolic substance are combined include polyvinyl alcohol, methyl cellulose, hydroxyethyl cellulose, gum arabic, gelatin, and styrene-maleic anhydride copolymer. Thermal recording paper using these water-soluble adhesives has poor water resistance, and when water is spilled on the thermosensitive recording paper, the coated surface may dissolve or become stained, which is undesirable. Furthermore, as described in Japanese Patent Publication No. 51-29947, crosslinking with a compound having two or more 1.2 epoxy ring structures in the molecule provides excellent water resistance, but does not provide sufficient adhesive strength. Furthermore, it has little effect on improving storage stability. Also, one way to improve oil resistance is to provide a protective layer on the surface of the heat-sensitive recording layer, but this method has disadvantages such as increasing the cost of the heat-sensitive recording paper and not being able to suppress the penetration of plasticizer from the end surface.
以上のように、これまでのところ保存性、特に耐油性と
いった高度な市場の品質要求に充分に対応てきていない
のが現状である。As described above, the current situation is that the high quality demands of the market, such as storage stability, especially oil resistance, have not been fully met.

重量％使用する。That is, when this GMA-grafted polyvinyl alcohol is used, it exhibits sufficient power as an adhesive, and can also be used as a crosslinking agent for other adhesives to improve water resistance. Not only that, this GMA-grafted polyhinyl alcohol seems to react with the colored dye,
As a result, the solubility of the dye in oils and plasticizers is reduced, or even if it is soluble, there is no reaction or fading of the dye back to its original state. In other words, it has excellent oil resistance. GMA kraft polyvinyl alcohol is present in an amount of 0.1 to 30% by weight of the heat sensitive layer, preferably 1 to 20%.
Use % by weight.

It is also possible to use it in combination with other adhesives.
