PURPOSE:To manufacture a highly bright laminated metal plate, the whole of which is smoothened, by pressurizing from the surface through a transparent hard layer and burying a hard discontinuous layer into a comparatively soft layer. CONSTITUTION:A multi-layer film, laminated in the order of a layer B, a base thermoplastic resin layer a layer C, a printing ink layer and a layer E, a surface thermoplastic layer, is placed on a metal plate with said layer B facing the metal place surface,and after pressurizing with a planished roll or a flat plate and under the state of retaining the plate temperature T between the melting points of polymers constituting the layers B and E, the same is cooled and manufactured. A planished roll or the flat plate with sufficient smoothness finished by gloss chrome plating or the like is used. As the surface is smooth, visible incident light coming from upper surface directions of the laminated metal plate is passed through the transparent layer E with smooth surface and is incident into the layers B and C to produce the contrast and tone exactly as they are. |
