Abstract
PURPOSE: To obtain material for lithographic plate of excellent reproduction and resolution characteristics, by utilizing glow discharge and changing the oleophilic surface of printing plate material into a uniform and solid hydrophilic surface layer.
CONSTITUTION: The oleophilic surface of printing plate base material having an oleophilic layer in which the angle of contact of polybutadiene, acrylic ester, and polycarbonate with respect to water is preferably more than 60 degrees and the oxygen content is preferably less than 25wt%, is subjected to glow discharge treatment and is chemically changed into a hydrophilic surface; and thereby material for lighographic printing plate is made. Proper conditions applicable for glow discharge are: current frequency, 10W103kHz; output, 5W1000W; and pressure of pressure-reducing chamber, 0.1W5torrs.
