This invention relates to a transfer type thermal ribbon, and more particularly to a transfer type thermal ribbon provided with a near-end notification mark. Transfer type thermal ribbons are usually formed by providing a layer of heat-melting ink on one side of a thin base sheet. A thermal printer is used to perform recording using such a transfer type thermal ribbon. A thermal printer is equipped with a thermal head, and when the electric signal based on the printing command is converted into heat in the thermal head and this heat is applied to the transfer type thermal ribbon, the thermal part of the heat-melting ink layer of this thermal ribbon prints. The dots are transferred onto a sheet of paper, and one character is formed by a collection of dots on the printing sheet, and the characters are printed one after another in the same manner. In such a transfer type thermal recording system, it is desired that printing is not interrupted due to the end of the ribbon in the middle of a line or page being printed on printing paper. The present inventor found that to solve this problem, it is sufficient to provide a near-end notification mark on the ribbon. In other words, the presence of a near-end notification mark set in the middle of the ribbon is detected by an optical sensor installed at the printer's near-end notification mark passing position, and the printer is made to predict the end of the ribbon, allowing printing to continue for a while, but the printing is stopped. It has been discovered that the above requirements can be met by stopping the printer to replace the ribbon when a line or page is completed. As a result of further investigation, we found that with such ribbons, the thermal head passes through the near-end notification mark, so it is necessary to prevent the near-end notification mark from having a negative effect on the thermal head or printing. I discovered something. The present inventor completed the present invention based on such knowledge. In other words, this idea is a transfer method in which a thin film-like near-end notification mark made of a resin with a softening point of 150°C or higher and a coloring agent is provided on the opposite side of the base sheet from the base sheet surface on which the heat-melting ink layer is provided. It is a heat-sensitive ribbon. This invention will be explained below with reference to the drawings. In the figure, 1 is a transfer type thermal ribbon, 1' is the end of the ribbon,
2 is a heat-fusible ink layer, 3 is a base sheet, and 4 is a near-end notification mark provided in the middle of the ribbon 1. The resin used to form the near-end notification mark 4 is silicone resin, epoxy resin, cellulose resin, polyester resin, or styrene resin.
Contains maleic acid copolymer. The softening point of the resin is
The temperature must be 150°C or higher; if it is lower than that, it will not be possible to prevent the thermal head from stacking, which will cause printing problems. Mark 4 contains a coloring agent that colors this mark. When the heat-melting ink layer 2 is black, a white inorganic pigment is suitable. Mark 4 is 0.5~
It must be in the form of a thin film in the range of 5 microns; if it is less than 0.5 microns, it will not be detectable by an optical sensor due to insufficient density, and if it exceeds 5 microns, the thermal sensitivity of the heat-melting ink layer to the printing head will be insufficient. The transfer will be incomplete. The transfer-type thermal ribbon of this invention is prepared by preparing a ribbon 1 by providing a heat-melting ink layer 2 on one side of a base sheet, and then using a resin with a softening point of 150°C or higher, a colorant, and a volatile solvent in which the resin is soluble. For example, a desired ribbon can be manufactured by applying ink made of (MEK, toluene, methyl ethyl ketone) to form a near-end notification mark. The transfer-type thermal ribbon 1 manufactured in this way is equipped with cores 5, 5 shown in FIG. 1, so that when the near-end notification mark 4 passes, the mark can be read by an optical sensor 8 fixed to the printer. It is used by being placed between the thermal head 6 and the printing paper 7. Next, a manufacturing example and a comparative example of the transfer type thermal ribbon of this invention will be shown. Manufacturing example 1 A ribbon is made by providing a heat-melt ink layer consisting of wax, resin, and colorant on a 12 micron thick polyester base sheet, and then applying the following composition of ink to a thickness of 5 microns to make a ribbon. Ivy. [Resin] Thermoplastic polyester 30 parts by weight Resin [manufactured by Toyobo Co., Ltd., Vylon 20SS, softening point 163°C] [Colorant] Titanium dioxide 15 parts by weight [Solvent] MEK 80 parts by weight Toluene 20 parts by weight Production example 2nd A ribbon was made in the same manner as in Production Example 1, except that an ink having the following composition was applied. [Resin] Cellulose acetate 10 parts by weight [Daicel Chemical Industries, Ltd., LAC-70, softening point 270°C] [Coloring agent] Titanium dioxide 15 parts by weight [Solvent] MEK 120 parts by weight Production example 3 Ink of 0.5 micron A ribbon was made in the same manner as in Production Example 1, except that the coating was applied to a certain thickness. Comparative Example 1 A ribbon was made in the same manner as in Production Example 1, except that a thermoplastic polyester resin with a softening point of 123°C (Vylon 30SS, manufactured by Toyobo Co., Ltd.) was used instead of the thermoplastic polyester resin with a softening point of 163°C. Comparative Example 2 A ribbon was made in the same manner as in Production Example 1, except that the ink was applied to a thickness of 10 microns. Next, the following table shows the presence or absence of states king and the clarity of printing of each ribbon of Production Examples 1 to 3 and Comparative Examples 1 and 2. The test was conducted using Cano Word 45 manufactured by Canon Inc. as a thermal printer. Presence or absence of states king: Each ribbon was printed using a thermal printer, and the presence or absence of states king was indicated by the near head notification mark for the heat sensitive head. Print clarity: Shown as the print condition on the print paper when the thermal head passes over the near-end notification mark.

[Table] As is clear from this table, the ribbon of this invention does not contain resin with a softening point of 150°C or higher, and compared to ribbons with thick film notification marks, there is no states king and the printing is clearer. is also good. As described above, according to this invention, printing can be performed without any problem even when the thermal head reaches the near-end notification mark, and it is possible to obtain a transfer-type thermal ribbon that is free from stacking with respect to the thermal head.
