PURPOSE:To strip smoothly and satisfactorily an unexposed photopolymerizable composition layer from a substrate by adjusting the cohesion of a photopolymerizable composition layer to the substrate to a specified relatively high value and by specifying the angle of stripping. CONSTITUTION:The cohesion of a photopolymerizable composition layer laminated on a substrate together with a transparent support to the substrate is adjusted to a relatively high value, and the force required to separate the unexposed parts of the photopolymerizable composition layer from the exposed parts is >=1.0kg/mm.<2>. When the angle of the stripping of the support from the substrate is adjusted to 0-90 deg., stress produced in the photopolymerizable composition layer during stripping concentrates on the boundaries between the exposed and unexposed parts, so the unexposed parts are stripped smoothly and satisfactorily to form a sharp image. |
