Slide blank, and process for producing a slide therefrom
First Claim
1. A slide blank comprising:
- a support at least part of which is essentially transparent;
an imageable layer superposed on one face of the support, the imageable layer not being substantially sensitive to visible radiation but comprising a color-forming composition, which, upon imagewise exposure to actinic radiation, forms a colored material, thereby forming in the imageable layer an image which can be viewed in transmission; and
a protective layer superposed on the imageable layer on the opposed side thereof from the support, at least part of the protective layer being essentially transparent;
the support, imageable layer and protective layer being secured together to form a slide blank having a thickness of at least about 0.8 mm, and the thickness of the protective layer being such that no part of the imageable layer containing the color-forming composition is more than about 0.2 mm from one external surface of the slide blank.

Abstract
A slide blank comprises a support at least part of which is essentially transparent; an imageable layer superposed on one face of the support, the imageable layer not being substantially photosensitive but comprising a color-forming composition, which, upon imagewise exposure to actinic radiation, forms a colored material, thereby forming in the imageable layer an image which can be viewed in transmission; and a protective layer superposed on the imageable layer on the opposed side thereof from the support, at least part of the protective layer being essentially transparent; the support, imageable layer and protective layer being secured together to form a slide blank having a thickness of at least about 0.8 mm, and the thickness of the protective layer being such that no part of the imageable layer containing the color-forming composition is more than about 0.2 mm from one external surface of the slide blank. This slide blank can be imaged to produce a ready-mounted slide.

19. A slide comprising:
-
a support at least part of which is essentially transparent; an image layer superposed on one face of the support and comprising an imagewise distribution of a colored material forming an image which can be viewed in transmission; and a protective layer superposed on the image layer on the opposed side thereof from the support, at least part of the protective layer being essentially transparent; the support, image layer and protective layer being secured together to form a slide having a thickness of at least about 0.8 mm, and the thickness of the protective layer being such that no part of the image layer containing the colored material which forms the image is more than about 0.2 mm from one external surface of the slide. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)

33. A process for producing a slide, the process comprising:
-
providing a slide blank comprising a support at least part of which is essentially transparent;
an imageable layer superposed on one face of the support, the imageable layer not being substantially sensitive to visible radiation but comprising a color-forming composition, which, upon imagewise exposure to actinic radiation, forms a colored material, thereby forming in the imageable layer an image which can be viewed in transmission; and
a protective layer superposed on the imageable layer on the opposed side thereof from the support, at least part of the protective layer being essentially transparent;
the support, imageable layer and protective layer being secured together to form a slide blank having a thickness of at least about 0.8 mm, and the thickness of the protective layer being such that no part of the imageable layer containing the color-forming composition is more than about 0.2 mm from one external surface of the slide blank; andexposing the slide blank to actinic radiation, and thus forming in the imageable layer an image which can be viewed in transmission, thereby producing a slide. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41)
