We investegated the effects of changing softening point of the ink binder resin and adding detergent to it on the recording sensitivity of dye transfer type thermal sheets. Falling down the softening point results in increase of sensitivity. However, the addition of some detergent with the low melting point was more effective. It is expected that the static sensitivity is improved by selecting suitable polymers coated on paper and adding some electron acceptors to them.
We have munufactured the experimental sheets possessing as sensitive as one of commercial thermal recording papers. Sample copies could be well received by G-II type facsimile.
