To provide a laminate sheet for manufacturing an electrostatic printing master plate, an electrostatic printing mater plate for forming an image of high resolution and a method for manufacturing the master plate by utilizing the laminate sheet and a light emitting.
The laminate sheet 1 for manufacturing an electrostatic printing master plate comprises a light absorbing layer 3 containing a light absorbing substance on a conductive layer 2b of a conductive base material 2 having the layer 2b at least on a front layer, and a heat shrinkable resin layer laminated on the layer 3 and having a volume resistivity of a range of 1012 to 1018 Ω.cm. A light of a desired pattern is emitted to a heat shrinkable resin layer 6 of the laminate sheet for manufacturing the electrostatic printing master plate, a heat shrinkage is generated at the layer 6 of an emitted area to be perforated. Thus, the master plate having an insulating pattern layer made of the layer 6 is formed.
