Example 4 First, a writing layer was provided in the same manner as in Example 1, and then a light-shielding layer having the following composition and a thickness of 15 μm was provided.

[0041]

Further, a pressure-sensitive adhesive layer having a thickness of 2 μm made of an acrylic resin-based pressure-sensitive adhesive was provided to obtain a pressure-sensitive transfer tape.

Comparative Example 1 A pressure-sensitive transfer tape was obtained in the same manner as in Example 1 except that the aluminum vapor-deposited layer was not provided.

Comparative Example 2 A pressure-sensitive transfer tape was obtained in the same manner as in Example 1, except that the thickness of the aluminum vapor-deposited layer was changed to 80 Å.

Comparative Example 3 A pressure-sensitive transfer tape was obtained in the same manner as in Example 3, except that the thickness of the light-shielding layer was changed to 60 μm.

With respect to the pressure-sensitive transfer tapes obtained in the above Examples and Comparative Examples, the white light transmittance of the pressure-sensitive transfer layer was measured using a photometer using a tungsten lamp as a light source. Next, each of the pressure-sensitive transfer tapes was cut into a strip having a width of 1 cm, and the pressure-sensitive transfer layer was coated on a black photographic mount (glossy paper).
And evaluated whether a blue transfer layer was visible. Further, a black pencil, a black oil-based ballpoint pen, and a fountain pen made of black ink were used to write on the blue transfer layer, and it was evaluated whether the written characters and symbols could be clearly read.

[0047]

[Table 1]

As is clear from Table 1, when the pressure-sensitive transfer tape of each of the above Examples in which the white light transmittance of the pressure-sensitive transfer layer was in the range of 0.1 to 10% was transferred, a black photograph was taken. Even if it is transferred on the backing paper, the transfer layer can be visually recognized,
When the white light transmittance of Comparative Examples 1 and 2 exceeded 10%, it was confirmed that visual recognition was impossible. In addition, it was confirmed that burrs were generated at the time of transfer in the pressure-sensitive transfer tape having a white light transmittance of less than 0.1% (Comparative Example 3). Further, the blue transparent writing layer used in the examples is excellent in writability, and it is possible to write characters and symbols neatly with a pencil or a ballpoint pen and a fountain pen on the transferred blue transparent writing layer, and to write written characters. And symbols were clearly legible. On the other hand, when the white light transmittance of Comparative Examples 1 and 2 was written on the transfer layer exceeding 10%, the written characters and symbols could not be read due to the influence of the base.

[0049]

According to the recording method of the present invention, a pressure-sensitive transfer layer of a pressure-sensitive transfer tape is transferred onto a transfer-receiving surface which cannot be directly written with a general writing instrument such as a pencil or a ball-point pen, and a general transfer method is applied thereon. Therefore, writing can be easily performed on the transfer surface as described above with a general writing instrument.

Furthermore, the transferred pressure-sensitive transfer layer reliably shields the reflected light from the transfer surface, so that the transfer object is not only white paper or a colorless film, but also colored paper containing black or dark color, or a colored film. Information written on a transfer layer transferred to a photo, a printed surface, a painted surface, or the like can be clearly read.
