JP-A-141279 discloses a multicolor heat-sensitive recording material capable of forming a full-color image. This heat-sensitive recording material has three heat-sensitive color-developing layers that develop different colors, and full color can be developed depending on the degree of color development of each layer. Specifically, the heat-sensitive recording material has a first side from the front side.
A thermosensitive coloring layer, a second thermosensitive coloring layer, and a third thermosensitive coloring layer are sequentially provided, and each layer is heated by a thermal head. In the heat-sensitive recording material, the heat-sensitive color development temperature is set lower toward the surface side layer, and at least the two layers from the top have the dye fixed by ultraviolet rays after color development. Therefore, the coloring density of the already-colored layer does not increase when the lower layer of the layer that has already been colored by heating is being heated. In the recording method using the heat-sensitive recording material, the first color-forming layer is heated to a first temperature to develop a color, and thereafter, ultraviolet rays are irradiated to stop the color development and fix the dye. Next, the second color-developing layer is heated to a second temperature for color development, and ultraviolet rays are similarly irradiated to stop the color development and fix the dye. Finally, recording is completed by heating the third color developing layer to a third temperature to develop color.

することができる。According to the present invention, when the multicolor heat-sensitive recording material is taken out from the tray and conveyed to the printing apparatus, the coefficient of static friction between the feeding roller and the recording material is set to 1.5 or more to improve the feeding performance of the recording material by the roller. Moreover, by setting the coefficient of static friction between the back surface of the fed recording material and the surface of the next second recording material to be 1.5 or less, the laminated recording materials are easily slipped. As a result, only the uppermost sheet of the recording material is reliably delivered by the delivery roller and does not slide on the roller during conveyance, so that the recording material is accurately supported at a predetermined position on the transfer drum. Therefore, it is possible to prevent position rubbing on the drum due to poor conveyance of the recording material and prevent defective coloring. The present invention is not limited to sheet paper, but can be applied to roll paper.

Then, the recording material is irradiated with light to decompose the diazonium salt compound contained in the second thermosensitive coloring layer 110, and sufficient heat that can be recorded is applied to the first thermosensitive coloring layer 111 to develop a color.
At this time, strong thermal energy is applied to the first thermosensitive coloring layer 111, but the diazonium salt compound 13 has already been applied.
No color is developed because 1 is decomposed and the color development ability is lost.

The static friction coefficient is measured according to JIS K 7125 (Plastic film and sheet friction coefficient test method) and JIS P 8147 (Paper and board friction coefficient test method). And there is a tilting method. The coefficient of static friction referred to here is the ratio of the frictional force that tries to prevent the initial movement of the paper and the force that is applied vertically to the paper (the state in which a heavy object is placed on the paper). Now, assuming that the static friction force when the sliding motion occurs is F μ s {gf} and the vertical load by the weight is F n {gf}, the static friction coefficient μ s
It is represented by μ s = Fμ s / F n , represented by five values rounded to 2 digits below the decimal point average by JIS Z 8401 (rounding of numbers) of the test values.

も適用することができる。According to the present invention, when the multicolor thermosensitive recording material is taken out from the tray and conveyed to the printing apparatus, the coefficient of static friction between the feeding roller and the recording material is set to 1.5 or more, and the feeding ability of the recording material by the roller is improved. And the coefficient of static friction between the back surface of the recording material to be fed out and the surface of the next second recording material was set to 0.5 or less so that the recording materials in the laminated state were easily slipped. As a result, only the uppermost sheet of the recording material is reliably delivered by the delivery roller and does not slide on the roller during conveyance, so that the recording material is accurately supported at a predetermined position on the transfer drum. Therefore, it is possible to prevent position rubbing on the drum due to poor conveyance of the recording material and prevent defective coloring. still,
The present invention is not limited to sheet paper, but can be applied to roll paper.
