Abstract:
1. A method for producing a resin pattern, the method comprising at least the steps (1) to (7) in this order: (1) A coating step of coating a photosensitive resin composition on a substrate; (2) A solvent removal step of removing the solvent from the applied photosensitive resin composition; (3) An exposure step of patternwise exposing the photosensitive resin composition from which the solvent has been removed, to an active radiation; (4) A development step of developing the exposed photosensitive resin composition using an aqueous developer liquid; (5) An overcoating step of providing an overcoat layer on the developed photosensitive resin composition; (6) A heat-treating step of heat-treating the photosensitive resin composition on which the overcoat layer has been provided; and (7) a removal step of removing the overcoat layer, wherein: the overcoat layer contains a compound selected from the group consisting of dextrins, celluloses and poly(meth)acrylic acid ester copolymers, and the thickness of the resin pattern after the heat treatment step of step (6) is 4 to 100 μm.
