Abstract
Abstract A simplified method for photoimaging a photosensitive layer produces in situ a radiation-opaque photomask on the photosensitive layer or on a cover sheet of the layer. A nonvisible latent image is toned and the toner is transferred to a layer or cover sheet to form an actinic radiation-opaque photomask.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
56 words
A process for photoimaging a photosensitive layer comprising the steps: (a) forming an actinic radiation-opaque image on the layer or on a transparent cover sheet thereon; (b) exposing the image-bearing layer to actinic radiation by which the layer is photoimaged; (c) removing the cover sheet if one is used; and (d) developing or fixing the photoimage.
Claim 2
Dependent Claim
56 words
A process for photoimaging a photosensitive layer comprising the steps: (a) forming an actinic radiation-opaque image on the layer or on a transparent cover sheet thereon; (b) exposing the image-bearing layer to actinic radiation by which the layer is photoimaged; (c) removing the cover sheet if one is used; and (d) developing or fixing the photoimage.
Claim 3
Dependent Claim
60 words
The process of Claim 1 in which the image is formed by transfer onto the layer or onto the cover sheet by (i) forming a latent image on a magnetic or electrostatic recording surface; (ii) toning the recording surface with opaque toner to form a toner image; and (iii) transferring the toned image to the photosensitive layer or cover sheet.
Claim 4
Dependent Claim
22 words
The process of Claim 1 in which the image is transferred directly onto the layer and is removed during development or fixing.
Claim 5
Dependent Claim
24 words
The process of Claim 1 in which the image is transferred directly onto the layer and remains on the photoimage after development or fixing.
Claim 6
Dependent Claim
16 words
The process of Claim 1 in which the photosensitive layer is supported on a polymeric film.
Claim 7
Dependent Claim
16 words
The process of Claim 2 in which the latent image is derived from an electronic signal.
