A thin layer containing a suitable pigment in a polymeric binder is striped on a film base to provide, in the header region of a microfiche a surface that is receptive of titles (e.g., written, printed or typed images), makes photographically recorded images eyeball readable, is translucent to visible light, yet transparent to photographically active radiation (i.e., radiation capable of being detected after processing using conventional photosensitive materials and processes) thereby permitting conventional reproduction of the entire microfiche including the header region.
