Abstract (en)
[origin: WO2013124575A1] The present invention relates to the formation of color laser images that can be viewed in various colors. The shades of gray are produced by non-reflective black spaces in a laserable layer that mask the adjacent sub-pixels and cause various colors to appear depending on the angle at which the document is viewed. The invention can be used for official documents.
