PROBLEM TO BE SOLVED: To provide an inner package sheet excellent in appearance and made of an antiviral polyvinyl chloride-based sol composition excellent in antiviral property.SOLUTION: In one embodiment, an antiviral polyvinyl chloride-based resin inner package sheet is obtained by coating a substrate surface with an antiviral polyvinyl chloride-based sol composition which contains 0.1 to 7.5 pts.wt. of a sulfonic acid-based surfactant and 10 to 100 pts.wt. of a plasticizer with respect to 100 pts.wt. of polyvinyl chloride resin for paste, the sulfonic acid-based surfactant being added to the polyvinyl chloride-based resin for paste in a production process of the polyvinyl chloride-based resin for paste. In another embodiment, the above antiviral polyvinyl chloride-based inner sheet contains 20 to 70 pts.wt. of the plasticizer with respect to 100 pts.wt. of the polyvinyl chloride-based resin for paste. There are alkyl hydrocarbon aromatic sulfonic acid-based compound, alkyl sulfonic cid ester-based compound or the like as the sulfonic acid-based surfactant, however alkyl benzene sulfonic acid-based excellent in antivirus system is preferable.COPYRIGHT: (C)2015,JPO&INPIT
