Abstract

In order to provide a coating material for formation of an antistatic/high refractive index film possessing superior antistatic effects, as well as an antistatic/anti-reflection film covered transparent material laminated body provided with superior antistatic effects and anti-reflection effects obtained by this coating material, and a cathode ray tube possessing this laminated body which is provided with antistatic effects, electromagnetic wave shielding effects, anti-reflection effects, and the effect of increase in contrast, the following are provided: a coating material comprising a dispersion fluid containing a mixture of an antimony doped tin oxide fine powder and a black colored electrically conductive fine powder; an antistatic/anti-reflection film covered transparent material laminated body containing a film layer of the coating material on the surface of a transparent substrate, and a specific low refractive index film layer; and a cathode ray tube possessing on its surface a first layer film containing a mixture of an antimony doped tin oxide fine powder and a black colored electrically conductive fine powder, and a second layer film containing silica sol.
