Abstract

PURPOSE:To transfer an ink image with high quality irrespectively of the surface condition of a transfer paper, a wax layer having a melting point of lower than that of an ink layer is provided on the surface of the ink layer of an ink doner sheet for heat-sensitive recording. CONSTITUTION:A heat-fusible ink obtained by adding an oil and a pigment to carnauba wax or an ester wax and having a melting point of about 70-90 deg.C is applied onto a base layer 5 consisting of a condenser paper, a polyester film or the like which has a thickness of about 5-15mum to provide the ink layer 6. Then, a heat-fusible wax 7 obtained by excluding the pigment from the ink layer composition is applied onto the ink layer 6. The layer of the wax 7 has a melting point of about 50-70 deg.C. The ink is applied in a quantity of 3-5g/m<2>, while the wax is applied in a quantity of 5-8g/m<2>.

る。In the above configuration, to explain the printing operation based on FIG. 1←), a plurality of thermal recording heads 3 arranged in a row
(only one is shown) is driven in accordance with a recording signal, the heat-melting ink 2 on the part of the pace 1 that comes into contact with the head 3
The melted ink 2' is transferred to the recording paper 4, so that a transferred image corresponding to the recording signal is formed on the recording paper 4, making it possible to transfer it to recording paper using plain paper. , Conventional ink donor sheets for thermal recording impregnate heat-molten ink into the surface of the transfer paper, so they are not easily affected by the surface of the transfer paper.For example, Bekk smoothness of the surface of the transfer paper If the time is longer than 20 to 30 seconds, the ink will not be applied uniformly and this will cause a change in image quality.

Although this problem is eliminated, the large size of each image causes resolution deterioration.

ものである。The present invention has been made in view of the above, and in order to enable high-quality transfer without being affected by the surface of the transfer paper, a wax layer having a lower melting point than the ink layer is provided on the surface of the ink layer. The present invention provides an ink donor sheet for thermal recording.

以下、本発明による感熱記録用インクドナーシートを詳

熱溶融性ワックス層７とよ多構成される。FIG. 2 shows an embodiment of the present invention, which includes a base layer 5 made of capacitor paper or polyester film with a thickness of about 5 to 15 μm, carnauba wax, and ester wax, to which oil is added as a softener and as a colorant. A heat-melting ink layer 6 containing a pigment and having a melting point (softening point) of about 70° C. to 90° C. is coated on the paste layer 5 at about 3 to 5 f//m2, and this ink layer 6, the pigment is removed and the melting point is set to about 50 to 70°C, and the hot melting wax layer 7 is coated on the surface of the hot bath melting ink layer 6 at a rate of 5 to 8 g/m2. .

熱溶融性インク層６の転写し易くなる条件が作られる。In the above configuration, the base layer 5 and the hot-melt ink layer 6 are made in the same manner as a conventional ink donor sheet, but
The heat-melting wax layer 7 is colorless or transparent, and has a melting point lower than that of the heat-melting ink layer 6, as described above. Therefore, when the thermal recording head is driven in accordance with the recording information and generates heat, the heat-melting wax layer 7 covers the surface of the transfer paper over a wide range of the size of the recording dots.
Conditions are created that facilitate transfer of the heat-melting ink layer 6.

なく転写が行われる。That is, the ink layer 6 and the wax layer 7 are heated in response to the heating of the thermal recording head, and the wax layer 7 with a low melting point on the surface of the transfer paper melts before the ink layer 6 melts, helping the ink to penetrate. Therefore, transfer is performed without being affected by the surface properties of the transfer paper.

発明者による実施の結果、ベック平滑度２０〜１００秒
程度まで一様な画質の得られることが確認された。As a result of implementation by the inventor, it was confirmed that uniform image quality could be obtained up to a Bekk smoothness of about 20 to 100 seconds.

画質のインク像転写を行うことができる。As explained above, according to the ink donor sheet for thermal recording of the present invention, since a wax layer having a lower melting point than the ink layer is provided on the surface of the ink layer, high quality ink image transfer is possible regardless of the surface condition of the transfer paper. It can be performed.
