PURPOSE:To prevent degradation in sensitivity particularly in low humidity environment by using a layer dispersed with fine condutive powder in photosetting resins as an undercoating layer. CONSTITUTION:A layer dispersed with fine conductive powder of conductive metallic oxides such as tin oxide and indium oxide, carbon black, aluminum, silica, zeolite, or the like in photosetting resins such as epoxy resin, urethane resin, polyester resin, acrylic resin melamine resin, or the like is used as an undercoating layer. The fine conductive powder to be dispersed in the resins is preferably 10-60wt%. |
