METHOD OF FORMING COLORED UNEVEN PATTERNS, AND THERMAL TRANSFER FOIL |
摘要 |
<p>Thermal transfer oil (4) formed by laminating a mold releasing layer (4b) about 0.02 mu m in thickness, a transparent colored protective layer (4c) about 2 mu m in thickness, a reflecting layer (4d) about 0.03-0.05 mu m in thickness and a layer (4e) of a thermoplastic resin on one surface of a base film (4a) about 12-25 mu m in thickness is laminated on a substrate (11) consisting of a metal sheet constituting a dial of a timepiece. The base film (4a) is then removed from the transfer foil (4), which is thereafter thermally pressed by a mold (21). A pressing surface (22) of the mold (21) has a fine uneven pattern, which is transferred to the colored protective layer (4c), reflecting layer (4d) and layer (4e) of a thermoplastic resin.</p> |
