Document Type and Number:
Japanese Patent JP7024217
Kind Code:
B2
Abstract:
To provide a resin molding having a PVA-based polymer and a cellulose fiber as a raw material, the resin molding excellent in optical characteristics, mechanical characteristics, heat characteristics and water resistance.SOLUTION: A resin molding includes a polyvinyl alcohol-based polymer, a cellulose fiber and a crosslinking agent. A saponification degree of the polyvinyl alcohol-based polymer is 90 mol% or more and less than 100 mol%. A hydroxyl group of the cellulose fiber is partially substituted by a carboxyl group. An average fiber width of the cellulose fiber in the resin molding is 3-200 nm. The crosslinking agent includes a polymer of a molecular weight 10,000 or more and less than 5,000,000.SELECTED DRAWING: None
