PURPOSE: To obtain easily articles having the indication of distinct marks, characters, designs or patterns and the like by applying a coloring material on a metallic plate being applied with fluorocarbon resin and thus indicating marks, characters, designs, patterns and the like.

CONSTITUTION: Fluorocarbon resin is applied on a rough surfaced metallic plate and by applying a coloring material thereon, there are indicated marks, characters, designs, patterns and the like. For the film after being applied with fluorocarbon resin, it is preferable that heating and baking are effected at the temperature of 450°C or lower and thereafter a coloring material is applied thereon. As a rough surface treating method, there is employed a etching method, barrel grinding method, hair line method, mechanical rough surface treating method, or the like. The degree of the rough surface is important in consideration of raising the adhesion between the coloring material and fluorocarbon resin, as usual, and it is preferred to be rough-surfaced in the order of 0.5 - 5 μm at the average roughness (Ra). The coated film thickness of clear fluorocarbon resin to be applied is usually selected from the range of 5 - 100 μm as a drying or baking coated film.
