PRODUCTION OF METALLIC PLATE COATED WITH PATTERNED RESIN

摘要

PURPOSE:To form coloring and a pattern without necessitating an engraving roll and a mask by bringing a metallic plate coated with resin into contact with dyeing liquid and irradiating the surface of the resin coating layer on the said metallic plate with laser in the visible and infrared regions and also scanning this laser. CONSTITUTION:A spacer 6 for liquid sealing is provided in an outer edge part between a glass plate 2 and a coated film 4. A dyeing liquid layer is constituted by enclosing dyeing liquid 3 into the space which is comparted by these glass plate 2, the coated film 4 and the spacer 6. The surface of test material immersed in the dyeing liquid 3 is irradiated with laser beams 1 in the visible and infrared regions through the glass plate 2. Further a pattern can be formed by scanning laser in the inside of the metallic plate coated with resin. A multicolor patter can be formed by utilizing the other dyeing liquid to change hue and performing immersion and irradiating treatment.
