Abstract
A color-negative photographic print medium for restricting the copying of an image in the medium utilizing a pattern of removable color-subtractive microdots depth-wise positioned anywhere within a transparent protective overcoat and a support layer which supports at least one image-forming layer is disclosed. The microdots are undetectable by the unaided eye, but detectable by copying machines programmed to prevent copying when microdots are detected.
