  • Patent number: 6342145
    Abstract: Methods of producing aluminum picture frames having two regions of different colors. Aluminum frame stock is coated with a colored maskant or paint. Selective regions of the coated frame stock are abraded, and then anodized and dyed a second color absorbed by the exposed regions. In a second embodiment, aluminum frame stock is etched, anodized, and dyed a first color. The frame stock is then selectively abraded to remove regions of the first color, and then anodized and dyed a second color so the abraded regions absorb the second color. In a third embodiment, the frame stock is first etched, anodized, and dyed a first color. Selective areas of the frame stock are protected using an etch-resistant mask and is then etched stripping the unmasked regions of the first color and then anodized again and dyed a second color absorbed by the unmasked regions. The mask is then chemically removed.
