Abstract:
A direct drawing lithographic printing plate precursor, which comprises a water-resisting support having provided thereon an image-receiving layer, an image being to be formed on the image-receiving layer with an oil-based ink by an electrostatic ink jet system,wherein said water-resisting support has at least a resin coating layer on the side opposite to the side on which the image-receiving layer is provided, wherein said resin coating layer comprises a mixture containing from 10 to 90 wt % of a low density polyethylene having a density of from 0.915 to 0.930 g/ml and a melt index of from 1.0 to 30.0 g/10 min., and from 10 to 90 wt % of a high density polyethylene having a density of from 0.940 to 0.970 g/ml and a melt index of from 1.0 to 30.0 g/10 min., wherein the surface of said resin coating layer has a Bekk's smoothness of from 5 to 2,000 sec/10 ml, and wherein said water-resisting support has a conductive layer having a specific electric resistance value of 1010 &OHgr;Â·cm or less on the image-receiving layer side surface thereof and on at least one end face thereof.
