PURPOSE: To efficiently manufacture a metallic sheet with high decorative property by applying a specified release agent on the surface of the metallic sheet in manufacturing the designing property metallic sheet by providing a hard printing layer on the surface of the metallic sheet and roughening the surface of the metallic sheet by working.
CONSTITUTION: Applied layers 14 of release agent are provided on the inside surface of two stainless steel sheets 12 and the hard printing layer 16 which consists of hard powder such as chromite powder is provided between them. In such a case, the release agent is a release agent contg. 50-75wt.% Si and its composition is made of 60wt.% glass powder, 70wt.% SiO2, 4wt.% Al2O3, 15wt.% Na2O, 9wt.% CaO, 2wt.% MgO, 10wt.% water glass, 5wt.% diatomaceous earth and 25wt.% water. And, chromium nitride, metallic chromium, silica, various kinds of carbides or the like in addition to chromite powder are usable for the hard printing layer 16. Thus, a prepared assembled body 10 is rolled down with rolling rolls 18, 18 by a prescribed quantity, the hard powder for printing is made to cut into the surface of the steel sheet 12 through the applied layer 14 of reiease agent and a rough uneven surface is formed on the surface.
