  • Publication number: 20210219433
    Abstract: The present invention aims to provide a method of producing a pattern-transferred product with simple steps, the method being capable of producing a pattern-transferred product having good adhesion between a transferred pattern and the transfer-receiving body. The method of producing a pattern-transferred product of the present invention includes a step of forming a transfer pattern on a dissociation layer of a transfer sheet including at least a porous layer on a support and the dissociation layer on the porous layer; a transferring step, the step being selected from a step of transferring the transfer pattern to a transfer-receiving body having an adhesive surface or a step of transferring the transfer pattern to a transfer-receiving body via an adhesive material; and a step of removing adhesion from the surface of the transfer-receiving body or from the adhesive material.

  • Patent number: 10990010
    Abstract: The present invention is a photosensitive resin composition to be used in an etching process in which an etching treatment is conducted with an etching solution containing hydrofluoric acid or ammonium fluoride. The photosensitive resin composition comprises at least (A) an acid-modified epoxy acrylate, (B) a photopolymerization initiator, (C) a blocked isocyanate compound, and (D) a filler. The etching process involves forming a photosensitive resin layer comprising said photosensitive resin composition, on at least one surface of a substrate; exposing and then developing the photosensitive resin layer; baking the photosensitive layer; and conducting an etching treatment with an etching solution containing hydrofluoric acid or ammonium fluoride.
