Abstract
Abstract Method of dyeing a pattern analogous to the grain of wood onto the surface of a blank consisting of aluminum or alloys thereof having a film of anodic oxidation thereon. A coloring composition containing oil dye is dropped on a water surface to diffuse, distribute or spread the coloring composition on the water surface in a patterned manner. The surface to be dyed of the blank is brought into contact in flat or inclined fashion with the patterned composition on the water surface to thereby adsorb coloring components into pin holes in the surface. The water surface is a stationary water surface or a flowing water surface.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
118 words
A method of dyeing a pattern resembling wood grain upon the surfaces of formed blanks of anodic oxide film-coated aluminum or alloys thereof which comprises the steps of depositing in a patterned manner unto the surface of the water on a water tank an oily coloring composition containing an oil dye, a vehicle therefore and a solvent, said solvent being selected from the group consisting of a water soluble organic solvent and one or more of an oil group long chain fatty acid and a long chain alcohol; contacting said formed blank with the water surface bearing said deposited composition to transfer the deposited patterned oily composition from said surface to said anodic oxide film on said blank.
Claim 2
Independent Claim
118 words
A method of dyeing a pattern resembling wood grain upon the surfaces of formed blanks of anodic oxide film-coated aluminum or alloys thereof which comprises the steps of depositing in a patterned manner unto the surface of the water on a water tank an oily coloring composition containing an oil dye, a vehicle therefore and a solvent, said solvent being selected from the group consisting of a water soluble organic solvent and one or more of an oil group long chain fatty acid and a long chain alcohol; contacting said formed blank with the water surface bearing said deposited composition to transfer the deposited patterned oily composition from said surface to said anodic oxide film on said blank.
Claim 3
Dependent Claim
26 words
The method according to claim 1, wherein the surface to be dyed of said blank is contacted in a flat fashion with said patterned water surface.
Claim 4
Dependent Claim
26 words
The method according to claim 1, wherein the surface to be dyed of said blank is contacted in an inclined fashion with said patterned water surface.
Claim 5
Dependent Claim
15 words
The method according to claim 1, wherein said water surface is a stationary water surface.
Claim 6
Dependent Claim
15 words
The method according to claim 1, wherein said water surface is a flowing water surface.
