摘要:
The high-property, high-precision color filter has an active film layer formed on a transparent substrate and comprised of at least one or more of active alumina or active silica, and fine patterns in the form of dot, stripe, and/or other patterns formed on the active film layer by a dye of any desired color being taken up into fine holes in the active film layer, and further an overcoat layer placed on the active film layer and having no affinity to the dye.In the method for manufacture of the color filter, the step of forming the fine patterns comprises mounting a metal mask having specified patterns holes on the active film layer, mounting a transfer sheet having an ink layer containing a dye on top of the active film layer, and subsequent heating in an atmosphere of reduced pressure.According to the invention, it is possible to obtain a color filter having excellent properties, including smoothness, heat resistance, water resistance, and light-resistance, and fine patterns in three colors, red green, and blue, having excellent spectral properties, and which can be manufactured by a simple process.

A color filter in accordance with the present invention comprises an activated film layer (2) arranged on a transparent substrate (1), said activated film layer (2) having a color pattern formed thereon by permeating a dye thereinto, and a thin metal film pattern (3) formed on a portion, of said activated film layer (2), which requires the formation of a black mask. Accordingly, the color filter integrated into various display devices such as a liquid crystal display is capable of displaying an image having a high contrast. Further, a method for forming a color filter in accordance with the present invention comprises the steps of forming an activated film layer (2) on a transparent substrate (1); permeating a dye into said activated film layer (2) to form a color pattern; and performing an electroless plating to form said thin metal film pattern (3) which functions as a black mask. Accordingly, the method in accordance with the present invention is capable of easily forming a color filter capable of displaying an image having a high contrast.

摘要:
A transfer printing machine in which the articles to be transfer-printed are held in a holder made of a material which does not substantially expand when heated and the articles are heated by an infrared radiation heater to a predetermined temperature. A transfer sheet having symbols and/or designs formed thereon with thermo-diffusible dye is pressed by a pressing pad against the surface of the articles so that the symbols and/or designs are transfer-printed on the surfaces of the heated articles.
