  • Patent number: 6366333
    Abstract: A method is disclosed which can form a thin metal film in a cost-effective manner and by a simple process of applying a coating composition. The method involves applying a coating composition containing colloidal particles of noble metal or copper, as obtained by reducing a compound of the noble metal or copper in the presence of a polymeric dispersant, to form a coating film, and heating the coating film so that the colloidal particles present therein are fused together to form a thin metal film.

  • Patent number: 5531881
    Abstract: Disclosed is a simple correction method of defects in color layer, which occur in production of color filter. The method does not have the problems associated with the conventional correction methods. The present invention provides a method for correcting defects in a color filter, comprising:(a) forming an electrodeposited film having certain color by means of electrodeposition method on defect portions of a color filter which comprises a transparent substrate, a transparent electrode formed on at least a portion of the transparent substrate and a color layer having a color pattern formed thereon, wherein the color layer has defect portions that formation of the color layer is incomplete, and(b) curing the electrodeposited film with heat or ultraviolet light.

  • Patent number: 5439582
    Abstract: The present invention provides an improved process for producing a multicolor display by which a color filter having neither coloring failure nor size failure is obtained.The present invention provides a process comprising:(I) a photosensitive resin layer formed on an electric conductive layer is exposed to light through a mask having a desired pattern which is placed on the photosensitive resin layer, and developed to bare partially the surface of the electric conductive layer;(II) a colored layer is formed on the bared surface of the electric conductive layer by an electrodepositing process; and(III) the above steps (I) and (II) are repeated desired times and then the remaining photosensitive resin layer is eluted with a removing solution which preferentially or selectively dissolves the photosensitive layer, to bare the remaining surface of the electric conductive layer.

  • Patent number: 5227044
    Abstract: The present invention provides a process for producing a multicolor display without a photolithographic process which requires registration. The process comprises forming a transparent electroconductive layer on a transparent substrate, forming a desired colored layer patterned thereon, and subjecting the transparent electroconductive layer exposed between the gap of the patterned colored layers to a metal electroplating (or electrolytic reduction) to form a light-shielding layer.
