Abstract

PURPOSE: To provide copying paper suited to punching under high humidity atmosphere and superior in resolving power by providing conductive support body with film containing polyvinyl alcohol, on which water-proof surface layer is additionally placed.
CONSTITUTION: Film layer containing polyvinyl alcohol (preferably 88W99mol percent for saponification number and 500W2,400 for polymerization) is provided on conductive support sheet preferably with surface electric resistance of 104W101Ω through bonding agent. Then, water-proof layer such as plastic material, wax, etc. is painted to obtain copying paper. In order to provide support sheet with conductivity, it is recommended to pour kneeded conductive material such as carbon black or apply solution containing conductive power and bonding agent.
USE: Punch photoengraving machine, facsimile, etc.
