Title:
METHOD FOR PRODUCING CONCAVE-CONVEX SUBSTRATE USING SOL-GEL METHOD, SOL SOLUTION USED IN SAME, METHOD FOR PRODUCING ORGANIC EL ELEMENT USING SAME, AND ORGANIC EL ELEMENT OBTAINED THEREBY
Document Type and Number:
WIPO Patent Application WO/2013/065384
Kind Code:
A1
Abstract:
A method for producing a substrate having a concave-convex pattern has a step (S2) for forming a coating film by coating the substrate with a sol solution comprising a silica precursor, a step (S3) for drying the coating film, a pressing step (S4) for pressing a mold having a concave-convex pattern on the dried coating film with a pressing roll, a step (S6) for peeling the mold from the coating film, and a step (S7) for firing the coating film on which the concave-convex pattern has been transferred. The coating film is dried so that the ratio of coated film weight to dried weight when fired at 100°C in the drying step is 1.4 to 8.8. The coating film may also be heated in the pressing step.
