Abstract
A synthetic resin decorative material including an antistatic layer containing an electrically conductive film formed on a surface thereof without changing the color, design and pattern of the decorative material. The synthetic resin may be a synthetic resin decorative sheet/plate. The antistatic function of the antistatic layer is improved such that occurrence of cracks in the antistatic layer can be prevented when the decorative material having the antistatic layer is thermally molded. To prepare the decorative material, a transfer sheet is pressed while being heated onto a surface of a synthetic resin decorative base material including a synthetic resin sheet or plate. To prepare the transfer sheet, electrically conductive paint containing an electrically conductive matter formed by coating inorganic fine powder having a refractive index of 1.4 to 1.7 with an electrically conductive tin oxide is applied onto a 1 to 5 .mu.m thick transparent or semitransparent synthetic resin coating layer provided on a release sheet. The electrically conductive paint is coated on the synthetic resin coating layer to a thickness of 0.5 to 5 .mu.m when dried.
