Abstract
Printed matter includes a substrate comprising a vinyl chloride resin and a printing layer on the substrate, wherein the surface of the substrate has a static friction coefficient of from 0.04 to 0.06 and a dynamic friction coefficient of from 0.02 to 0.03 when the surface of the substrate is rubbed with standard adjacent fabrics for staining for color fastness test under a load of 200 g, wherein the surface of the printing layer has a static friction coefficient of from 0.35 to 0.50 and a dynamic friction coefficient of from 0.20 to 0.30 when the surface of the printing layer is rubbed with standard adjacent fabrics for staining for color fastness test under a load of 200 g.
