The present invention provides a resin convex mould for relief printing with a stable dimension precision and less damage to substrates when printing even thought printing time and again, and a method for producing organic EL elements using the resin convex mould. A light-sensitive resin composition obtained by fitting a prepolymer and single-function or multi-functional monomer is used as mould material, wherein the prepolymer is prepared by adding acrylic ester into a polymerisation product of polyester polyatomic alcohol and diisocyanates. |
