い。 It is preferable to color this acrylic resin liquid for impregnation with a coloring agent such as a pigment or dye.If it is colored in a hue different from the color of the flexible polyurethane foam sheet, the outer shell layer will be clearly visible and the appearance This is particularly preferable. The degree of impregnation with acrylic resin liquid is
The thickness is preferably 5 to 70% of the thickness of the flexible polyurethane foam sheet to be impregnated. If it is less than 5%, the outer shell layer becomes too thin compared to the overall thickness, resulting in a cuticle-like appearance, and pinholes are formed in the acrylic resin portion forming the outer shell layer, which is not preferable. When it exceeds 70%, the outer shell layer becomes too thick and lacks elasticity and flexibility, making it unsuitable for uses such as cushion materials and shoe insoles. From the viewpoint of cushioning properties, the degree of impregnation with the acrylic resin liquid is preferably 10% to 50% of the thickness of the flexible polyurethane foam sheet.
