Abstract
A method for manufacturing a decorative sheet from a metallic sheet comprises the steps of flame-spraying a coating material onto the surface of a metallic sheet to form a flame-sprayed layer thereon, and roughening the surface of the flame-sprayed layer. The surface of the metallic sheet may be etched in the shape of some pattern to form the flame-sprayed layer, and may be covered with at least one mask having a pattern opening which extends through the mask and has a pattern so as to form the pattern on the surface of the metallic sheet by flame-spraying of the coating material through the pattern opening of the mask.

A method for manufacturing a decorative sheet from a metallic sheet comprising the steps of:
- etching the surface of the metallic sheet to form an etched pattern therein;
- and
- flame-spraying a material different from the material of the metallic sheet only on the etched pattern of the metallic sheet through a mask.
A method for manufacturing a decorative sheet from a metallic sheet comprising the steps of:
- selectively flame-spraying a first coating material onto the surface of the metallic sheet through a first mask to form a pattern of a first coating layer;
- and
- flame-spraying a second coating material onto at least a portion of the uncoated surface of the metallic sheet which is not coated by the first coating layer through a second mask to form a second pattern of a second coating layer;
- and selectively performing a color development treatment on the first and second coating layers through a third mask so as to form color developed portions on the first and second coating layers.
