Invention Description (i) [Technical Field to which the Invention belongs] The present invention relates to a method for manufacturing a clock dial, especially a reproduction of a cloth pattern, a paper pattern, a stone pattern, etc. Manufacturing method of patterned transparent clock dial, and dial manufactured by this method. [Advanced technology] In recent years, the driving method of watches and clocks has undergone a technical innovation from battery-driven to solar-powered charging. Solar-powered clocks are made of glass, ceramics, shells, plastic, and other light-transmitting dials. This solar charge-driven timepiece's light passes through the dial to operate the solar cell built in the timepiece body to obtain driving force. The dials of plastic clocks and watches often have a premium feel (plus value), and various patterns are added to the surface, back, or both of the dial. This pattern is formed by injection molding a resin in a mold. A pattern is formed in the mold, and when the resin is injected and hardened, a copy of the pattern is obtained. This mold was previously made by mechanical method, engraving method, gold engraving method, etc., so it is of high value. There are also those who make molds by the electroforming method (electroforming method), but in order to obtain a sufficient thickness for feasible resin injection molding, long-term electroforming is required, and the price is still high. Clock dials are multi-variety and small-volume production, so the price of molds is high, which leads to high finished product °°. Therefore, there is a demand for cheaper clock dial dials with patterns. Japanese Patent Application Laid-Open No. 9-164589 discloses that the surface pattern of the shell is mold-molded by electroforming, and the pattern of the metalized shell is used on the resin mold sheet.
