PROBLEM TO BE SOLVED: To improve shielding property and transparency by laminating a black layer composed of metal oxide or metal sulfide and a metal thin film layer in order, into an electromagnetic wave shielding pattern shape, on a transparent substratum. SOLUTION: A resist layer having a reverse pattern of an electromagnetic wave shielding pattern shape is formed on a transparent substratum 1. For the transparent substratum 1, transparent material such as glass and acrylic resin is used. A metal thin film layer 3 is formed on the whole surface of a black layer 2 composed of metal oxide or metal sulfide. The resist layer is eliminated together with the black layer 2 and the metal thin film layer 3 which are laminated on the resist layer. Since electromagnetic wave is shielded by the metal thin film layer 3 having the electromagnetic wave shielding pattern shape excellent in conductivity, electromagnetic wave shielding property is improved. By laminating the black layer 2 below the metal thin film layer 3, a transparent board side of a conducting part shows black color, so that metal reflection is not generated and transparency is also excellent.

PROBLEM TO BE SOLVED: To obtain a high-definition color reproduction function and an improved recognition property by forming a hydrophilic transparent dyed layer on a transparent base, forming an electroless plated layer on the hydrophilic transparent dyed layer in a pattern, and forming a black pattern that matches the electroless plated layer in the hydrophilic transparent dyed layer. SOLUTION: A hydrophilic transparent resin layer 2 is formed on a sheet- shaped or film-shaped transparent base 1 such as glass and electroless plating is performed onto it, thus forming an electroless plated layer 3 in a pattern. Simultaneously with the formation of the electroless plated layer 3, a black pattern 4 that matches the electroless plated layer 3 is formed in the hydrophilic transparent resin layer 2. Then, a coloring matter is dyed to the hydrophilic transparent resin layer 2 as a hydrophilic transparent dyed layer 5. A hydrophilic transparent dyed layer where the coloring matter is dyed to the hydrophilic transparent resin layer is formed in one configuration layer, a high- definition color reproduction function is achieved and a recognition property can be improved with only one filter even if an electromagnetic wave shielding function and a color reproduction function are both required.
Abstract:
PURPOSE:To improve smoothness, heat resistance, water resistance, and light resistance of a color filter by forming a pattern colored in optional color by dyeing inside of fine pores in an activated film layer comprising activated alumina or activated silica which has been formed on a transparent substrate, and forming an overcoated layer having no affinity with the dye on the pattern. CONSTITUTION:An activated film layer comprising activated alumina and/or activated silica is formed on a transparent substrate, which is colored by dyeing the inside of fine pores in the activated film layer with a dye. Then, dot pattern, stripe pattern, or other pattern are formed on the same plane of the activated film layer in an optional color. Further, an overcoated layer having no affinity with the dye is formed thereon preventing revaporization of dye molecules which have been captured in the fine pores of the activated film layer, preventing simultaneously contamination of the film layer by unnecessary materials.

PROBLEM TO BE SOLVED: To obtain a transfer material provided with a protective film excellent in the resistance to foil burrs, wear resistance and following capability to a curved surface of a material to be transferred. SOLUTION: In the transfer material 1 provided with a transfer layer 20 on a base material sheet 11 having releasing property, the protective layer 21 contained in the transfer layer 20 contains a thermal cross-linking reaction product formed from a polymer A, a polyfunctional isocyanate and a colloidal silica particle and produced by heating a protective layer before thermal cross-linking which is formed using a protective layer material prepared by mixing the polymer A having 100-300 g/eq, (meth)acryl equivalent, hydroxide value of 20-500 and weight average molecular weight of 5,000-50,000, and active energy curing resin composition comprising the polyfunctional isocyanate and the colloidal silica particles having free silanol group on the surface of the particle with each other.

Abstract:
PURPOSE:To prevent a resist mask or a substrate from the generation of distortion due to heat and to improve the accuracy of a color filter by forming a transfer sheet and the resist mask on an active film layer and projecting laser beams to the mask to transfer dye to the active layer and dye the layer. CONSTITUTION:The active film layer 2 is formed on the transparent substrate 1 and then the transfer sheet 3 is allowed to contact with the layer 2. The sheet 3 is obtained by layer constitution consisting of a base sheet 3a transmitting laser beams and an ink layer 3b including dye, binder, and so on. The resist mask 4 having pattern holes 4a is formed on the sheet 3. When a laser beam is projected form the upper part of the mask under pressure-reduced atmosphere, the projected dye is transferred only to parts corresponding to the holes 4a to dye the layer 2. Said process is repeated in accordance with the number of necessary colors. Then, the sheet 3 and the mask 4 are removed and an overcoat layer 5 sealing fine holes 6 of the layer 2 is formed. Even if the setting order of the sheet 3 and the mask 4 is reversed, the similar result can be obtained. Consequently, the generation of distortion due to heat can be prevented and the accuracy of the color filter can be improved.
Abstract:
PURPOSE:To obtain a key cap with a reverse pattern of a character, a symbol or the like with a large dyeing depth, by a method wherein a key cap provided with a reverse pattern of a character, a symbol or the like by a dip thermal dyeing method is subjected to a dry heat treatment at a temperature at which dyeing can be performed. CONSTITUTION:When the key cap 1 provided with a reverse pattern of a character, a symbol or the like by a dip thermal dyeing method is subjected to a dry heat treatment at a temperature at which dyeing can be performed, the molecular motion in the resin at the surface of the base material of the key cap becomes vigorous, resulting in an enlargement of the spacing between molecules, and molecules of a thermally transferable dye 2 deposited in a surface layer part 3 are diffused into an inner layer part 4.
