Abstract:
1. A process for producing a substrate having a coating resin layer by using a coating apparatus having a spouting means for spouting a resin layer precursor against at least a substrate to be coated, a fastening table for fastening said substrate thereon, a moving means for moving said spouting means or said fastening table in a horizontal direction, a carrying-in means for carrying-in said substrate on said fastening table, a carrying-out means for carrying-out said substrate from said fastening table, and a waste liquid pan for receiving said resin layer precursor spouted from said spouting means outside said substrate, said process comprising the steps of (a) carrying-in said substrate on said fastening table by said carrying-in means and fastening said substrate at said fastening table; (b) while moving said spouting means or said fastening table in a horizontal direction by said moving means, spouting said resin layer precursor from said spouting means to apply said resin layer precursor onto said substrate to form a resin layer precursor layer on said substrate; (c) carrying-out said substrate having said resin layer precursor layer from said fastening table by said carrying-out means; and (d) drying and curing said resin layer precursor layer on said substrate to form a coating resin layer on said substrate, wherein upon the application of said resin layer precursor onto said substrate in said step (b), said waste liquid pan is lifted to make such that said resin layer precursor which is spouted from said spouting means outside said substrate stays between said waste liquid pan and at least a pair of edges of said substrate, where said edges of said substrate are coated with said resin layer precursor.
