Abstract:
In a high-precision color filter (14) having excellent properties of the present invention, a dye (4) is deposited in the pores (3) of an active membrane layer (2) composed of at least one of active alumina and active silica and formed on a transparent substrate (1), so that fine dot patterns, striped patterns or other desired patterns of a desired color can be formed on the same plane of said active membrane layer (2) and an over-coat layer (6) having no affinity with the dye (4) is formed further thereon. A step of forming the above-mentioned patterns in the production of the color filter (14) of the present invention comprises placing a metal mask having predetermined pattern holes on said active membrane layer (2), putting thereon a transfer sheet having an ink layer containing the dye (4) and heating the sheet in an atmosphere under a reduced pressure. In accordance with the present invention, a color filter (14) can be obtained which has excellent properties such as flatness, heat resistance, water-proofness or light resistance, and a fine pattern having excellent spectral characteristics of red, green and blue, and can be produced by a simple production process.

PROBLEM TO BE SOLVED: To provide an in-mold patterning transfer sheet capable of preventing the contamination of a mold at the time of in-mold patterning and capable of sufficiently preventing the precipitation of an oligomer. SOLUTION: The in-mold patterning transfer sheet comprises a base material film 35 constituted of polyester resins different in the content of the oligomer in a thickness direction and a transfer layer 32 provided on one side of the base material film 35. The outside part 36b positioned on the outermost surface side of the other surface 35b, to which the transfer layer is not provided, of the base material film 35 is formed of a resin with a thickness of 0.1-5.0 μm and an oligomer content of below 0.5 wt.% and an intermediate part 37 is formed of a resin with an oligomer content of 1 wt.% or above. The outside part 36b and the intermediate part 37 are constituted of the same kind of a resin and integrally constituted so that a boundary is absent between both of them.

Abstract:
PROBLEM TO BE SOLVED: To correct a defect of a translucent mesh electromagnetic wave shield material while reducing required labor and time significantly without causing any problem of appearance by forming a black mesh point or a gray pattern at a defective part of the translucent mesh electromagnetic wave shield material. SOLUTION: When a black defect 2 is present in the lattice-like pattern 1 of a translucent mesh electromagnetic wave shield material, the black defect 2 is removed by irradiating it with laser from a laser irradiator having a slit mechanism for irradiating only the black defect part 2. Black ink 4 employing ink or carbon paste for black matrix of color filter is then applied in the form of mesh points by means of needles or dispensers arranged in specified pattern having mesh point frequency corresponding to the aperture rate of the lattice- like pattern 1 and then it is dried. According to the method, a translucent mesh electromagnetic wave shield material in which defect is corrected can be obtained while reducing required labor and time significantly.
Abstract:
PROBLEM TO BE SOLVED: To improve reduction in the contrast of a display screen by successively laminating an electroless plating layer and a black resist layer on a hydrophilic transparent resin layer in a pattern shape such that a part where the black resist layer exists can be seen in black from both front and rear sides. SOLUTION: A hydrophilic transparent resin layer that is not blackened is laminated on a transparent substrate 1. An electroless plating nucleus for chemical plating is formed on the surface and in the layer. Then, the hydrophilic transparent resin layer is treated in an electroless plating liquid, thus forming an electroless plating layer 4. Then, the unwanted part of the electroless plating layer 4 and that of a blackened hydrophilic transparent resin layer 3 are eliminated. Furthermore, the electroless plating layer 4 where a part 5 in that a black resist layer exists is formed is treated by an etching liquid, thus forming a hydrophilic transparent resin layer 6 where the black color has been partially eliminated.
Abstract:
PURPOSE:To simplify production process and to improve productivity by providing an active film layer consisting of activated alumina or activated silica on a substrate and fixing a dye thereto by using a dye resist mask. CONSTITUTION:The active film layer 2 consisting of the activated alumina or activated silica is formed on the transparent substrate 1 and the dye resist mask 4 provided with patterned holes 4a is brought into tight contact therewith. A stage for heating a sublimatable due or solid dye which is evaporated by thermal melting under a reduced atmosphere by a heater 8 and migrating and fixing the evaporated dye to the layer 2 is repeated according to the required number of colors. The amt. of the dyes to be migrated is controlled by a shutter 9 provided between the substrate 1 and the heater 8. A transparent over coatlayer 5 for sealing the fine holes 6 of the layer 2 is finally formed. The production process is thereby simplified and the productivity is improved.
