The present invention provides a sheet material and an artificial leather with excellent design properties, including metallic luster and shading. Provided is a design sheet material including a light-transmissive base material and a colored part containing a metallic and/or metalloid element disposed on at least one surface of the light-transmissive base material. When the saturation C* is measured under the condition that light from a light source is incident at an angle of 45 degrees on the surface of the design sheet material on the light-transmissive base material side, with 0 degrees being the angle of specular reflection of said light, the value obtained by subtracting the saturation C*(110 degrees), which is observed at a position 110 degrees on the light source side from said 0 degrees, from the saturation C* (15 degrees), which is observed at a position 15 degrees on the light source side from said 0 degrees, is 10 or greater.

Abstract

The purpose of the present invention is to provide an adhesive tape which is capable of exhibiting excellent adhesive force to a silicone-based adherend. An adhesive tape according to the present invention has an adhesive layer that contains a (meth)acrylic copolymer. A laminate which is obtained by bonding the adhesive tape to a silicone rubber that is affixed to an SUS304 plate is left to stand for 72 hours in an environment at 25°C and 50% RH, and is subsequently subjected to a peel test in which the adhesive tape in the laminate is peeled at 180° from the silicone rubber under conditions of 23°C, 50% RH, and a peeling rate of 300 mm/min using a tensile tester. If the surface, from which the adhesive tape has been separated, of the silicone rubber after the peel test is cleaned at least eight times with ethyl acetate and is subsequently subjected to TOF-SIMS measurement, the peak intensity (26/total) of negative ions in a region where m/z is 26 with respect to the peak intensity (total) of all negative ions is 2.50 × 10-3 or more.
