Irradiation with ultraviolet light from a 120 W high-pressure mercury lamp (manufactured by Nippon Battery Co., Ltd.) in a nitrogen atmosphere
- An acrylic hard coat resin was applied to a base material (polyethylene terephthalate film) having a thickness of 125 1, and hardened to form a hard coat layer having a thickness of 5 xm.
- This surface material was crimped and attached at room temperature to the surface of a liquid crystal display with a touch input device to create a pen input device.
- Various evaluations were performed in the same manner as in Example 1 using this. The results are shown in Table 1.
- a resin liquid containing 100 parts by weight of an ultraviolet-curable acryl-based resin, 2 parts by weight of an ataryl resin-based bead having a particle size of 5 to ⁇ ⁇ , and a small amount of a silicone resin was prepared.
- the resin solution was applied to one side of a transparent polyethylene terephthalate film having a thickness of 10 ⁇ m and cured by irradiation with ultraviolet rays to form a resin layer having a thickness of 5 / zm.
- An acrylic pressure-sensitive adhesive solution was applied to the opposite surface of this polyethylene terephthalate film and dried to prepare a surface material. This surface material was pressure-bonded to the surface of a liquid crystal display with a touch input device at room temperature to form a pen input device.
- Various evaluations were performed using this as in Example 1. The results are shown in the table. Shown in 1.
- Polyethylene terephthalate finolem having a thickness of 100 ⁇ is coated on one side with a polyhydric acid prolatatatontriol and a polyol liquid (100 parts by weight) mainly composed of a polysiloxane compound and hexamethylene isocyanate.
- An isocyanate solution (90 parts by weight) as a main component was mixed and applied to form a resin layer having a thickness of 300 m. After heating the resin layer at 12 for 20 minutes, it was peeled off from the polyethylene terephthalate film to form a soft resin film.
- An acrylic pressure-sensitive adhesive solution was applied to the surface of the soft resin film and dried to prepare a surface material.
- the slipperiness was not appropriate, and further, in the comparative example 1, the rough feeling was particularly insufficient, and a good writing feeling could not be obtained.
- the feeling of dents was particularly insufficient, and a good writing feeling could not be obtained.
- the roughness was particularly insufficient, and a good writing feeling could not be obtained.
- a fluorine-based compound may be contained in the composition for forming a surface layer instead of the polysiloxane-based compound.
- the surface material may be adhered to the front surface of the display with an appropriate adhesive without providing the adhesive layer on the substrate surface.
