Abstract: A method for recovering a cyclic olefin resin includes: a composite material containing at least a cyclic olefin resin, and a different resin that is different from the cyclic olefin resin is dissolved in a solvent capable of dissolving the cyclic olefin resin to produce a solution, and a different resin component, which contains the different resin, is precipitated out; the solution is filtered and a filtrate is obtained by removing the different resin component; and a composition containing the cyclic olefin resin is obtained from the filtrate.

Abstract: A heat shrinkable film manufacturing method includes: preparing packaging materials including film labels having resin layers mainly including thermoplastic resin and print layers; preparing first and second virgin raw materials of thermoplastic resin; recovering, from the resin layers, a recycled raw material of thermoplastic resin; and forming a resin-based film including the recycled raw material as a raw material so as to have a core layer and a surface layer layered on the core layer wherein the forming the resin film includes at least one of: forming the core layer including at least the recycled raw material and the first virgin raw material and the surface layer mainly including the second virgin raw material; and forming the core layer including the first virgin raw material and the surface layer including the second virgin raw material and at most 25 wt % of the recycled material.

Abstract: A manufacturing method for a heat shrinkable film includes: preparing a packaging material that includes film labels having a resin layer mainly contains thermoplastic resin, and a printed layer; recovering first and second recycled raw materials from the resin layer; and forming a resin film with a core layer including the recycled raw materials and a surface layer layered onto the core layer and includes thermoplastic resin. Recovering the recycled raw materials includes: forming, into individual pieces, the packaging material and/or the resin layer from which the printed layer has been removed; and separating the printed layer from the packaging material and/or pieces of the packaging material to obtain the resin layer from which the printed layer has been removed and/or pieces of the resin layer from which the printed layer has been removed. One of the recycled raw materials is polyester-based resin, and the other is polystyrene-based resin.

Abstract: The present invention relates to a first antigen-binding molecule, a second antigen-binding molecule, and a combination thereof. The second antigen-binding molecule binds to an antigen/antigen-binding molecule complex containing a first antigen and the first antigen-binding molecule, and enhances the binding activity of the first antigen-binding molecule to the first antigen.

Abstract: This method for producing a resin film includes the following: preparing, as a starting material, at least either a film label that includes an ink layer and a resin layer or a resin bottle to which the film label is fitted; recovering a thermoplastic resin having a specific gravity of less than 1 from the starting material; and obtaining a resin film having a specific gravity of less than 1 by extrusion molding, while having a molding material contain the recovered thermoplastic resin, wherein the recovering includes the following: dividing the starting material or the resin layer into individual pieces; removing the ink layer from the film label or each piece of the film label; and subjecting the starting material, the resin layer or pieces of the starting material or the resin layer to specific gravity separation.

Abstract: Provided are a developing roll for an electrophotographic device and a method for manufacturing a developing roll for an electrophotographic device, with which toner fusion and toner filming are suppressed. A developing roll for an electrophotographic device includes a shaft body and an elastic body layer formed on an outer circumference of the shaft body. The surface of the elastic body layer has a plurality of large protruding parts having a width of 3.0 to 12 ?m and a height of 3.0 to 12 ?m, and the side surface of the large protruding part 16 has a plurality of small protruding parts which form convex-concavity having a ten-point average roughness Rz of 2.0 to 4.0 ?m.
