Abstract
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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
52 words
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.
Claim 2
Independent Claim
52 words
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.
Claim 3
Dependent Claim
29 words
A method for manufacturing a decorative sheet from a metallic sheet as claimed in claim 1, wherein said flame-sprayed material is powder of one of brass, ceramic and glass.
Claim 4
Dependent Claim
39 words
A method for manufacturing a decorative sheet from a metallic sheet as claimed in claim 1, wherein the surface of the flame-sprayed layer in substantially the same level as the surface of the unetched portion of the metallic sheet.
Claim 5
Dependent Claim
54 words
A method for manufacturing a decorative sheet from a metallic sheet as claimed in claim 1, wherein the etched portion of the metallic sheet is set to be of a predetermined depth such that the etched portion of the metallic sheet is not exposed even when the surface of the flame-sprayed layer is damaged.
Claim 6
Dependent Claim
32 words
A method for manufacturing a decorative sheet from a metallic sheet as claimed in claim 1, wherein the outside surface of the flame-sprayed layer is polished after the mask has been removed.
Claim 7
Dependent Claim
26 words
A method for manufacturing a decorative sheet from a metallic sheet as claimed in claim 1, wherein the mask is made of a heat resistant material.
Claim 8
Dependent Claim
27 words
A method for manufacturing a decorative sheet from a metallic sheet as claimed in claim 1, wherein said flame-sprayed material is a mixture of different coating materials.
Claim 9
Dependent Claim
27 words
A method for manufacturing a decorative sheet from a metallic sheet as claimed in claim 7, wherein said flame-sprayed material is a mixture of aluminum and brass.
Claim 10
Dependent Claim
27 words
A method for manufacturing a decorative sheet from a metallic sheet as claimed in claim 7, wherein said flame-sprayed material is a mixture of aluminum and resin.
Claim 11
Independent Claim
115 words
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.
Claim 12
Independent Claim
115 words
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.
Claim 13
Dependent Claim
37 words
A method for manufacturing a decorative sheet from a metallic sheet as claimed in claim 10, wherein said color development treatment of the exposed portions is performed by an oxidation or reduction reaction of the exposed portions.
