ABSTRACT:
A packaged photographic product is disclosed comprising a) a silver halide based photographic material contained within a packaging enclosure, and b) a time and temperature integrating device for providing a visually observable indication of cumulative thermal exposure which is removably attached to the packaging enclosure with a pressure sensitive adhesive. In accordance with a preferred embodiment, the packaged photographic product further comprises an outer enclosure, and the packaging enclosure comprises a second enclosure within the outer enclosure, and the time and temperature integrating device is removably attached to the second enclosure with a pressure sensitive adhesive, and is visible through a transparent or open section of the outer enclosure. In accordance with a second embodiment of the invention, a process for monitoring the thermal exposure of a silver halide based photographic material prior to and after loading in a photographic camera is disclosed comprising a) removably attaching with a pressure sensitive adhesive a time and temperature integrating device for providing an indication of cumulative thermal exposure on a surface of an enclosure containing the photographic material, b) loading the photographic material in a photographic camera, and c) transferring the time and temperature integrating device from the surface of the enclosure to a surface of the camera at the time of loading the camera with the photographic material.
