RESIN RELIEF PRINTING PLATE FOR RELIEF PRINTING, AND PROCESS FOR PRODUCING ORGANIC EL DEVICE OBTAINABLE THEREOF

摘要

PURPOSE: A resin convex plate for printing a convex plate and a manufacturing method of an organic EL device are provided to stabilize The size accuracy of the organic light-emitting layer of an organic EL device although manufacturing plural organic EL elements on one resin convex plate. CONSTITUTION: A resin convex plate for printing a convex plate is composed of a prepolymer formed by adding acrylate to the polymerization addition product of diisocyanate and polyester polyol and a photoresist resin composition material formed by mixing monofunction or the multi-functional Polymer. The resin convex plate for printing a convex plate has the JIS rubber hardness within the range of the Shore A 60~90°. The resin convex plate for printing a convex plate is developed with water cleanser. The weight change rate of before and after immersion is the swelling ratio within the range of 0.2~15% after continuously dipping for 24 hours In the environment or less of the room temperature 20~25°C about anisole, cyclohexylbenzene, and tetralin or mixed solvent which is aromatic system solvent melting and dispersing organic EL luminous body.
