Abstract

A photosensitive film assembly comprising;

a polymeric support having first and second side, said support being reflective to non penetrating radiation; and

a photosensitive layer on at least one of said first and second sides of said support.

Claims

1. A photosensitive film assembly comprising;

a polymeric support having first and second side, said support being reflective to non penetrating radiation; and

a photosensitive layer on at least one of said first and second sides of said support.

2. The photosensitive film assembly of claim 1 including first and second photosensitive layers respectively on said first and second sides of said support.

3. The photosensitive film assembly of claim 2 wherein said support is transmissive of penetrating radiation and said first and second photosensitive layers are directly exposed by an image of penetrating radiation.

4. The photosensitive film assembly of claim 1 wherein said photosensitive layer comprises a green-sensitized, polydisperse -4.0 MM, silver bromide t-grain layer.

5. The photosensitive film assembly of claim 2 wherein said first and second photosensitive layers comprise a green-sensitized, polydisperse -4.0 MM, silver bromide t-grain layer.

6. The photosensitive film assembly of claim 1 wherein said support includes a white reflective material.

7. The photosensitive film assembly of claim 6 wherein said white reflective material includes barium sulfate.

8. The photosensitive film assembly of claim 1 including a first screen adjacent to said photosensitive layer for converting a penetrating radiation image to a light image which exposes said photosensitive layer.

9. The photosensitive film assembly of claim 1 including a first and second screens respectively adjacent to said first and second photosensitive layers for converting a penetrating radiation image to light images which respectively expose said first and second photosensitive layers.
