- Examples 1 and 2 and Comparative Example 1 two types of yellow label and silver label were used, and in Example 3, a transparent sheet was used and a character pattern was printed thereon.
- the recording part (the part with the thermal transfer ink layer) of the printed matter obtained above and the non-recording part (the recording surface of the transferred body)
- D 65 the color difference E * ab of the L * a * b * color system of CIE and the value of (Aa *) 2 + (Ab *) 2 ] 1/2 were measured.
- the recording part of the printed matter (the part with the thermal transfer ink layer) and the colored layer of the base material of the thermal transfer sheet used were not provided.
- the color difference from the ink layer measured from the surface was measured using the same color difference meter CR-221 manufactured by Minoru Inc. as above.
- the recording portion of the printed matter when the silver label was superimposed on the printing surface side of the transparent sheet, and the colored layer of the base material of the used heat transfer sheet were used.
- the color difference from the ink layer measured from the surface not provided was measured. However, the measurement was carried out on the back side of the above-mentioned thermal transfer sheet without coating any layer such as a heat-resistant layer.
- conventional light source D 65 is a light source are use in illumination specified in JI SZ 8723 (1988), Ru conventional light source der the relative spectral distribution of standard illuminant D 65 of the colorimetric approximates.
- the standard light D 65 to be approximated is a light having a correlated color temperature of about 6504 K and is used to display an object color illuminated by daylight.
- Example 1 Yellow Label 64.32 9.02 92.97 17.46 37.80 -58.55 161.19 154.23
- Example 2 Yellow Label 64.18 9.12 93.53 31.02 37.18 20.21 85.22 78.51
- Transfer object (ink Recording surface of transfer object Printed part um E * ab [( ⁇ a y + layer) / colored sheet L a ai bi L 2 b 2
- the printed information obtained under the above printing conditions is visually observed from 5 m away from the printed information, and evaluated according to the following criteria.
- ⁇ The recorded information was slightly unclear, or the recorded portion was seen in a color different from the original color of the colored layer, and it was difficult to read the information a little.
- Table 3 below shows the evaluation results of the visual readability of the above Examples and Comparative Examples.
