Claim 1
Independent Claim
119 words
A thermal transfer material, comprising a support and an ink layer disposed thereon which comprises a binder and a colorant; said binder having a melt viscosity (η poise) satisfying the following formula: 1.9×10.sup.13 ·e.sup.-0.26T ≦η≦4.8×10.sup.17 ·3.sup.-0.26T, wherein T denotes a temperature (°C.) and e denotes the base of natural logarithm, in the range of 50-150° C.; and said thermal transfer material is capable of recording on a recording medium when both said thermal transfer material and said recording medium are moved past a recording head, during said recording said thermal transfer material being moved in a unit time more slowly than said recording medium so as to effect relative motion between said thermal transfer material and said recording medium.
Claim 2
Dependent Claim
