A method for coating with a coating liquid according to the present invention is a method for coating an object-to-be-coated with a coating liquid containing dispersed particles, using a die, wherein the flowage of the coating liquid within a manifoldprovided within the die is such that the deviation of the average flow rate of the coating liquid in the direction of the width becomes equal to or less than 60% of an average flow rate over the entire area of the manifold, in at least 80% of the area from a liquid supplying portionin the manifold to an end portion P of the manifold.

The method of cleaning a coated sheet according to the present invention is characterized in that dry wind is brown along the traveling direction of a film onto the surface of a coating layer wherein the solid content and the viscosity of the coating solution are within specified ranges. By this method, the thickness precision of the coating film can be improved in its large area, and the evenness of its in-plane optically functional property can be made even therein. The speed of the dry wind, the temperature of the wind, and the thickness of the dried coating film are preferably within specified ranges. In particular, the coated sheet is very useful as an optical material having good properties in an optically functional layer which is frequently used as a large-area coated sheet, an optical device having such an optically functional layer, an optically compensating layer, or an optically compensating plate. The coated sheet is particularly effective for an image display on which they are mounted.

The present invention provides a production method of a printed circuit board having a circuit pattern with a little variation in the thickness at a low cost without a special step for removal of a dummy pattern. The present invention is characterized in that an insulating layeris formed in a given pattern on one surface of a supporting substrate, a circuit patternis formed on the insulating layerwhile forming a dummy patternin an area free of the insulating layeron the one surface of the supporting substrate, and an unnecessary part of the supporting substrate, which is free of the insulating layerand the circuit pattern, is removed by dissolution together with the dummy pattern

Production method of printed circuit board

A wired circuit board having a terminal portion formed as a flying lead that can provide enhanced strength of the conductive pattern, both sides of which are exposed, by simple construction to effectively prevent disconnection of the conductive pattern. The wired circuit board having the terminal portion formed as the flying lead in which the both sides of the conductive pattern are exposed includes, in crossing areas where ends of a cover-side opening and ends of a base-side opening and the conductive pattern are crossed each other, (i) the widened portions formed in the conductive pattern or (ii) cover-side projections and base-side projections formed in the cover layer and the base layer, respectively.
