PRINTED METAL CONTAINER AND MULTICOLOR PRINTING THEREOF

摘要

This invention discloses a printed metal container having an organic resin coating film layer containing titanium oxide having photosensitivity characteristics of I x t1/2 < 100 mW.sec/cm<2> (where I is the optical intensity and t1/2 is the optical decay half life of surface potential) as a primer coating for printing on a metallic substrate. Disclosed also is a multicolor printing method comprising continuous transport with rotation of a metal container, uniform charging with deviated charging phases and exposure by migration of light emitted from a light source in synchronism with the transport of the container.
