Abstract: The invention refers to a color holographic foil for protection of goods and documents from forgery and falsification. It includes successively placed foil base (1), release layer (2), embossing layer (3), reflective layer (4) and adhesive layer (5). The embossing layer comprises smooth areas (6) and micro-relief areas (7). The thickness of the optical reflective layer (4) is inversely proportional to the depth of the depressions in the micro-relief areas. At least two of the micro-relief areas are dyed areas (10) with embossing layer colored with a dye in different saturations of a single color tone. The saturation is directly proportional to the depth of the depressions. At least one dyed area is a multi-bonded area (11), having at least one micro-relief boundary (12) and at least one smooth boundary (13). The topography of the micro-relief in said multi-bonded areas is different from the topography of the neighbouring dyed areas.
