A patterning method includes the steps of irradiating an excimer laser beam to a material layer so as to form a pattern on the material layer; and transferring onto a substrate, the material layer formed with the pattern; and irradiating the excimer laser beam to the material layer transferred onto the substrate so as to form a further pattern on the material layer.

Patterning method employing laser

A method of producing a transparent conductive film provided with supplementary metal lines, comprises the steps of forming a transparent conductive film composed mainly of indium oxide, tin oxide, or antimony oxide on a transparent substrate and forming metal lines through printing on the transparent conductive film by an intaglio or litho offset printing procedure a line pattern of metallorganic ink composed mainly of an organic noble metal containing gold, silver, or platinum and baking it for metallization.

Method of producing a transparent conductive film provided with

Disclosed is an intaglio printing process which comprises (a) forming an intaglio printing plate having groove patterns, (b) filling said groove patterns with an ink, (c) after drying said ink, forming a curable resin layer on the whole surface of the intaglio printing plate, (d) placing a body to be printed thereon without curing said resin layer, (e) curing the curable resin, and (f) stripping the body from the intaglio printing plate to form the ink patterns corresponding to the groove patterns of the intaglio on the body. There are also disclosed processes for producing a color filter, a black matrix and a circuit board.
