PURPOSE: To obtain the electrophotographic type planographic printing original plate having excellent electrophotographic characteristics and printing resistance by using metallic foil laminated by using an adhesive which is mixed with a cold setting type polyurethane resin and a carbon black and has a high electrical conductivity as the base material.
CONSTITUTION: The adhesive for the metallic foil and paper at the time of forming the metal foil-laminated paper is a mixture composed of the cold setting type polyurethane resin having the high electrical conductivity of ≤1×1014Ωcm volumetric resistance value and carbon black. Then, the electrophotographic planographic printing original plate which does not fog in spite of execution of plate making under a low humidity condition and has the good printing resistance is obtd. when the metal foil-laminated paper laminated by using the adhesive formed by mixing the cold setting type polyurethane resin and the carbon black and having the high electrical conductivity is used as the base material.
