Abstract

PURPOSE:To provide the pressure sensitive copy paper which is effective for preventing the forgery of a copy by a method wherein the copy is consisted of an upper sheet of paper having its back surface coated with a layer of developing agent dissolved or dispersed in a wax etc. and coloured pigment and a lower sheet of paper having a layer of micro capsule containing pressure sensitive dye oil. CONSTITUTION:For example, this pressure sensitive copy paper is constructed by the upper sheet of paper A having the layer 3 of coloured pigment and the developing agent (Ex: p-t-butylphenol zinc salt etc.) dissolved or dispersed in the wax (Ex: carnaba wax etc.) at the back surface of a base sheet 1 and by the lower sheet of paper B formed with the layer 4 of the micro capsule containing pressure sensitive dye oil [made to be micro capsule by applying a pressure sensitive dye such as diapylphtalyde etc. with a nonvolatile solvent Hisol SAS (trade mark owned by Nippon Petrochemical Co., Itd.)]. Then, an intermediate sheet of paper is made by printing the developing agent sisoolved or dispersed in a wax etc. and the colored pigment on the back surface of the lower sheet of paper. With this arrangement, an orange colour is remained even if a black copy character is processed by an ink erasing chemical.
