<p>The present invention addresses the problem of providing a method for producing a photosensitive resin element that has excellent productivity and good appearance. The present invention provides a method for producing a photosensitive resin element, which comprises: a step for obtaining a liquid blend by blending (a) a binder resin that has a weight average molecular weight of 5,000-500,000 and a carboxyl group content of 100-600 in terms of acid equivalent, (b) a photopolymerizable unsaturated compound, (c) a photopolymerization initiator, (d) acetone and (e) a non-acetone solvent, with the mass ratio of (d) the acetone to the total mass of (d) the acetone and (e) the non-acetone solvent being 30-98% by mass and with the ratio of the total solid content in the liquid blend being 30-80% by mass; and a step wherein the liquid blend is applied onto a supporting layer and dried thereon, thereby forming a photosensitive resin element on the supporting layer.</p> |
