PURPOSE:To improve stability and printing resistance of the titled layer by vaporizing a liquid hydrocarbon compd. at normal temp. and pressure, and introducing the obtd. gas to a vacuum system, followed by forming a coating layer on an aluminum substrate with a vapor grown film. CONSTITUTION:The aluminium substrate 2 is mounted on the supporting body of a lower electrode in a plasma polymerization apparatus, and the substrate is heated to a substrate temp. of 300 deg.C by a heater 4, after reducing the pressure of a bell jar to <=10<-4>Torr. While heating the substrate, argon gas is introduced into said apparatus, followed by glow-discharging the substrate whereby the surface of the aluminium substrate is cleaned by an ion-bombardment. Next. the introduction of the argon gas is stopped, and the apparatus is reduced to the pressure of <=10<-4>Torr, and a needle value 8 is opened, and benzene vapor is fed to the apparatus, followed by glow-discharging the substrate at the vacuum of 1.2X10<-1>Torr. After 5hr, the substrate provided with transparent carbon film having 10mum thickness is taken out from the apparatus. The obtd. carbon film is charged to positive, and is image-wisely exposed by radiation of UV rays, followed by developing it with a two component magnetic brush developer. Thus, the good image having high stability, printing resistance and long shelf-life is obtd. |
