Method for the direct electrodeposition of a chromium layer on a metal substrate and a lithographic sheet comprising a metal substrate covered with such an electrodeposited chromium layer.

摘要

Electrodeposition of chromium of selectively constituted crystalline character and grain texture on metal substrates, such as aluminum or steel base lithographic sheet to provide improved and directly chromium plated aluminum or steel base lithographic sheet capable of operatively functioning as a surface plate after exposure of an applied photo sensitive coating thereon.
