A laminated material includes a first base material, and a sheet material laminated on and integrated with a surface of this first base material. The first base material is made of a material selected from the group consisting of a biomass material, a plastic, a metal, a ceramic, a glass, a molded pulp, and a paper. The sheet material is substantially made of a plant-derived component. The sheet material has an absorption peak in a region of 1715 to 1725 cm−1 in an infrared absorption spectrum. The sheet material can be produced by removing a liquid component from a lignocellulose solution produced by dissolving a plant raw material in an organic acid. A laminated material is produced by laminating the sheet material on a surface of the first base material, and thermocompression-bonding the sheet material and the first base material.

Abstract

The purpose of the present invention is to provide a water-in-oil emulsion composition having improved dispersibility of polysaccharide-based particles. This water-in-oil emulsion composition is obtained by a water-in-oil emulsion composition production method comprising: a step A for preparing a base-use water-in-oil emulsion composition from an oil-phase composition and a water-phase composition; and a step B for mixing the base-use water-in-oil emulsion composition with particles mainly composed of a polysaccharide-based polymer selected from the group consisting of polysaccharides and polysaccharide esters. The water-in-oil emulsion composition excels in dispersibility with respect to particles containing a polysaccharide-based polymer as a main component.
