摘要

The present invention is to provide an antiviral vinyl-chloride-based resin composition having excellent antiviral properties, an antiviral sheet, an antiviral wallpaper, and interior decorative sheets. The antiviral vinyl-chloride-based resin composition is characterized by including: a specific amount of a poly(vinyl chloride)-based resin obtained by mixing a vinyl-chloride-based resin for paste with a suspension vinyl-chloride-based resin in a specific proportion; and a specific amount of a sulfonic-acid-based surfactant. One of the interior decorative sheets includes a surface layer including an antiviral poly(vinyl chloride)-based resin composition which includes a poly(vinyl chloride)-based resin including a poly(vinyl chloride)-based resin for paste and a suspension poly(vinyl chloride)-based resin and which further contains a sulfonic-acid-based surfactant and a plasticizer in specific amounts relative to the poly(vinyl chloride)-based resin. An essential point resides in that a poly(vinyl chloride)-based sol composition including a plasticizer and a poly(vinyl chloride)-based resin for paste containing a given amount of a sulfonic-acid-based surfactant is applied. Another interior decorative sheet includes a surface layer constituted of a poly(vinyl chloride)-based resin composition including a poly(vinyl chloride)-based resin and specific amounts, relative to the poly(vinyl chloride)-based resin, of a sulfonic-acid-based surfactant, a plasticizer, and a silicone-based copolymer. The antiviral wallpaper includes a base layer and a resin layer including a resinous ingredient including a vinyl chloride resin for paste into which a sulfonic-acid-based surfactant has been incorporated beforehand in an amount of 1.2% by weight or larger.
