という欠点がある。By the way, the resistance dots in thermal printer heads made from such resistance compositions have a drawback in that their resistance values vary widely. Also, when the resistance value of the main resistor dot is high (when the sheet resistance is 3Ω or more),
There is a drawback that the resistance value drifts to the negative side when voltage is applied.

ある。(Object of the invention) The present invention has been made to solve the above-mentioned drawbacks,
The object of the present invention is to provide a resistor composition capable of producing a thermal printer head with little variation in resistance value and in which the resistance value does not drift toward the negative side even when a voltage is applied when the resistance value is high. It is something to do.

たから他ならない。The power was increased by 0.1 watts from the starting level of 0.3 watts, and at that time, 1m5B (H ~ 9m5ec) was applied for 3 minutes.As a result, data as shown in the graph in Figure 1 was obtained, and the conventional example In contrast, those of the example did not shift significantly to the negative side, and the step stress was good.Also, the resistance value of the example did not shift significantly to the negative side. As is clear from the table, even though the dot resistance value of the example is the same as that of the conventional example, the variation in resistance value is smaller than that of the conventional example.This is due to the identification of the glass composition. There is no other way than that.
