熱記録材料に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a multicolor heat-sensitive recording material, and more particularly to a multicolor heat-sensitive recording material formed by laminating a plurality of heat-sensitive coloring layers having different color tones.

などが広く用いられている。A thermosensitive recording material is a material in which a thermosensitive coloring layer capable of forming a colored image by heating is provided on a support such as paper, and a thermal printer equipped with a thermal head is widely used for heating.

現象が少ないため多く利用されている。These conventional heat-sensitive recording materials include a colorless or light-colored leuco dye (color-forming main agent) having a rough ring, a lactam ring, a spiropyran ring, etc. in the heat-sensitive coloring layer, and a color that develops by reacting with this leuco dye when heated. Those containing a color developer (color development aid) are widely used because they have clear color tones and cause less fogging.

However, depending on the purpose of recording, in order to display particularly necessary data and numbers more clearly, the coloring of that part (
It goes without saying that it is desirable to be able to record with the display color (displayed color) different from the developed color of other parts.

Multi-color thermosensitive recording paper is generally formed by stacking two types of high-temperature and low-temperature coloring layers that develop different tones with different coloring heat energies on a support, and can be broadly classified into the following two types: Divided into types. One is to mix the color with the color tone of the low temperature coloring layer when coloring the high temperature coloring layer to obtain a color tone different from the coloring tone of the low temperature coloring layer, and the other is to color the high temperature coloring layer. In this case, by using a decoloring agent that decolorizes the low-temperature color-forming layer, only the color tone of the high-temperature color-forming layer is obtained without color mixture of the color tone of the low-temperature color-forming layer. As specific examples of these, the former is disclosed in Japanese Patent Publication No. 49-69, Japanese Patent Publication No. 4342-1972, Publication No. 27708-1977,

These are disclosed in Japanese Patent Application Laid-open No. 112, Japanese Patent Application Laid-Open No. 18048-1982, and Japanese Patent Application Laid-Open No. 47843-1983, respectively.

った。However, in the case of the former multicolor thermosensitive recording paper,
When coloring at a high temperature, the color tones that can be concretely achieved in order to mix the color with the color tone of the low temperature coloring layer are limited to black threads where the high temperature coloring tone is strong, such as red-black, blue-black, etc. There is. On the other hand, in the case of the latter multicolor thermosensitive recording paper, the combination of color tones can be freely selected, but when high temperature coloring occurs, it is necessary to provide a color erasing layer containing a color erasing agent to erase the color of the low temperature coloring layer. There is. It has been proposed to use aliphatic amines, aromatic amines, polyethers, etc. as such decolorizing agents. However, these decoloring agents have the disadvantage that they do not sufficiently decolor the coloring layer, resulting in mixed colors.
