Abstract

Abstract Thermal transfer recording is effected by providing a thermal transfer recording medium comprising a thermal transfer ink layer on a support, providing a thermal head having heat-generating elements, disposing the thermal transfer recording medium in contact with a record paper so that the thermal transfer ink layer contacts the record paper, energizing the heat-generating elements corresponding to a given recording image signal to heat the thermal transfer ink layer of the thermal transfer recording medium in a pattern, and separating the thermal transfer recording medium from the record paper to leave a recorded image of the heated thermal transfer ink layer on the record paper. Herein, the thermal transfer ink layer is supplied with a heat energy so as to assume a temperature of 35 - 60° C in the absence of energization of the heat-generating elements, and the heat-generating elements are energized while the heat energy is applied. Because of the heating, a recorded image of good quality is obtained and a part of these recorded by image is readily removed for correction by lifting-off.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 156 words
In a thermal transfer recording method, comprising providing a thermal transfer recording medium comprising a thermal transfer ink layer on a support, providing a thermal head having heat-generating elements, disposing the thermal transfer recording medium in contact with a transfer-receiving medium so that the thermal transfer ink layer contacts the transfer receiving medium, energizing the heat-generating elements corresponding to a given recording image signal to heat the thermal transfer ink layer of the thermal transfer recording medium in a pattern, and separating the thermal transfer recording medium from the transfer-receiving medium to leave a recorded image of the heated thermal transfer ink layer on the transfer-receiving-medium corresponding to the given recording image signal; the improvement wherein the thermal transfer ink layer is supplied with a heat energy so as to assume a temperature of 35-60°C in the absence of energization of the heat-generating elements, and the heat-generating elements are energized while the heat energy is applied.
Claim 2
Dependent Claim 156 words
In a thermal transfer recording method, comprising providing a thermal transfer recording medium comprising a thermal transfer ink layer on a support, providing a thermal head having heat-generating elements, disposing the thermal transfer recording medium in contact with a transfer-receiving medium so that the thermal transfer ink layer contacts the transfer receiving medium, energizing the heat-generating elements corresponding to a given recording image signal to heat the thermal transfer ink layer of the thermal transfer recording medium in a pattern, and separating the thermal transfer recording medium from the transfer-receiving medium to leave a recorded image of the heated thermal transfer ink layer on the transfer-receiving-medium corresponding to the given recording image signal; the improvement wherein the thermal transfer ink layer is supplied with a heat energy so as to assume a temperature of 35-60°C in the absence of energization of the heat-generating elements, and the heat-generating elements are energized while the heat energy is applied.
Claim 3
Dependent Claim 30 words
A recording method according to Claim 1, wherein the thermal transfer ink layer is supplied with the heat energy so as to assume a temperature of 40 - 50° C.
Claim 4
Dependent Claim 35 words
A recording method according to Claim 1, wherein the period after the energization of the heat-generating elements until the separation of the thermal transfer recording medium from the transfer-receiving medium is 0.2 - 80 msec.
Claim 5
Dependent Claim 35 words
A recording method according to Claim 3, wherein the period after the energization of the heat-generating elements until the separation of the thermal transfer recording medium from the transfer-receiving medium is 0.5 - 30 msec.
Claim 6
Dependent Claim 38 words
A recording method according to Claim 1, wherein a correction tape is bonded to at least a part of the recorded image and peeling the correction tape to remove said at least a part of the recorded image.
