Abstract
The fine-line pattern forming method is to form a pattern by transferring the pattern formed on the blanket of which surface is covered with an elastic material mainly composed of silicone resin, on a substrate on which a tack layer is formed. As an example thereof, the forming method of cathode-ray tube anode comprises a step of filling the groove of an intaglio with a graphite ink, a step of transferring the graphite ink in the groove of the intaglio on a blanket of which surface is covered with an elastic material mainly composed of silicone resin, a step of forming a tack layer on a substrate, a step of transferring and printing the pattern transferred on the blanket onto the substrate, a step of filling the groove of the intaglio with a phosphor ink, a step of transferring the ink in the groove of the intaglio on the blanket of which surface is covered with an elastic material mainly composed of silicone resin, a step of forming a tack layer on the substrate, a step of transferring and printing the pattern transferred on the blanket on the substrate on which the graphite pattern has been formed, a step of transferring an aluminum thin film possessing multiple pores as a metal-backed layer so as to cover a black matrix and a phosphor layer, and a step of firing the substrate covered with the aluminum thin film. The graphite ink comprises graphite powder, vehicle containing depolymerization type organic binder, and organic acid metal salt. The phosphor ink comprises phosphor powder and vehicle containing polymerization type organic binder.
