[발명의 효과][Effects of the Invention]

실시예 및 비교예의 감열기록재료의 표면저항값 및 결착력의 실험결과 표 1에서 볼 수 있는 바와같이 비교예의 경우 도전제의 양에 비례하여 표면저항값이 낮아짐을 알 수 있다.Experimental Results of Surface Resistance and Binding Force of the Thermal Recording Material of Examples and Comparative Examples As can be seen from Table 1, it can be seen that the surface resistance is lowered in proportion to the amount of the conductive agent in the comparative example.

그리고, 실시예 1과 2를 비교해 보면 동일 투입량에서 양이온의 도전제가 음이온의 도전제가 음이온의 도전제보다 더 효과적임을 알 수 있고, 특히 표면저항값②의 결과에서 알 수 있듯이 양이온성의 도전제는 음이온성의 도전제보다 습기에 대해서도 탁월한 효과를 나타냄을 알 수 있다.And, comparing Examples 1 and 2, it can be seen that at the same dosage, the cation conduction agent is more effective than the anion conduction agent than the anion conduction agent. It can be seen that it shows an excellent effect on the moisture than the conductive agent of the castle.

그러나, 결탁력 실험에서 알 수 있듯이 도포액의 조합에 있어서, 실리카의 결착제의 조합비에 따라 결착력의 차이가 있음을 알 수 있다. 즉, 실리카와 결착제의 비가 3/1이상의 경우는 도포시에 묻어나는 현상이 심하게 발생한다.However, as can be seen from the binding force experiment, it can be seen that there is a difference in binding force depending on the combination ratio of the binders of silica in the combination of the coating liquid. That is, when the ratio of silica and binder is 3/1 or more, the phenomenon which arises at the time of application | coating severely arises.

따라서, 본 발명은 유포감열 기록재료로서 실리카와 결착제의 일정비를 이루고 여기에 일정성질의 도전제를 투입함으로서 결착력이 우수하고 백(BACK)면의 표면저항값이 우수한 제품을 얻을 수 있는 매우 유용한 발명이다.Therefore, the present invention forms a constant ratio of silica and a binder as a diffusion thermal recording material, and by adding a conductive agent of a certain quality therein, a product having excellent binding strength and excellent surface resistance on the back surface can be obtained. It is a useful invention.
