Abstract
PURPOSE: To prevent development of residual dyes on a nonimage area and to obtain an original plate for printing prevented from fogging, by dispersing a resin- coated photoconductive pigment into a binder to form a photoconductive layer.
CONSTITUTION: A photoconductive pigment to be used is preferably a phthalocyanine pigment of particle diameter ≤2μ, and coated with a resin, such as polypeptide or phenol resin in 0.05W0.3μm thickness. Said 1pts.wt. resin-coated photoconductive pigment (a), and 0.01W100pts.wt. binder (b), preferably, novolak type phenol resin of 350W20,000 mean mole weight are dispersed into an organic solvent, the obtained photosensitive fluid is coated on a conductive substrate with its surface made hydrophilic, and dried on it to form a 1W50μm thick photoconductive layer for use in an original plate for printing.
