First Claim
Patent Images
1. A copy restrictive color-negative photographic print medium comprising:
- a support layer;
at least one image-forming layer supported by said support layer;
a clear protective overcoat above said at least one image-forming layer; and
a pattern of removable color-subtractive microdots, positioned between said support layer and said at least one image-forming layer, for causing the formation of resultant image microdots in a processed image;
wherein said resultant image microdots are substantially undetectable by casual observation under normal viewing conditions of said processed image.

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.
