1. A slide blank comprising:
- a support;
a mask layer having a substantially transparent central portion and a non-transparent peripheral portion surrounding the central portion; and
,an imageable layer which is not substantially sensitive to visible radiation but is imageable by exposure to actinic radiation to form an image which can be viewed in transmission,the support, mask layer and imageable layer being secured together so that the support and the imageable layer extend across essentially the entire transparent central portion of the mask layer, at least the portion of the support adjacent the central portion of the mask layer being substantially transparent.

Abstract
A slide blank comprises a support; a mask layer having a substantially transparent central portion and a non-transparent peripheral portion surrounding the central portion; and an imageable layer which is not substantially photosensitive but is imageable to form an image which can be viewed in transmission. The support, mask layer and imageable layer are secured together so that the support and the imageable layer extend across essentially the entire transparent central portion of the mask layer, at least the portion of the support adjacent the central portion of the mask layer being substantially transparent. This slide blank can be imaged to produce a ready-mounted slide.

18. A slide comprising:
-
a support; a mask layer having a substantially transparent central portion and a non-transparent peripheral portion surrounding the central portion; and
,an image layer bearing an image, the support, mask layer and image layer being secured together so that the support and the image layer extend across essentially the entire transparent central portion of the mask layer, the image layer also extending across at least part of the peripheral portion of the mask layer, and at least the portion of the support adjacent the central portion of the mask layer being substantially transparent, the image having a first section disposed adjacent the transparent central section of the mask layer so that the first section of the image can be projected by passing light through the image layer, the transparent central portion of the mask layer and the support, the image also having a second section disposed adjacent the peripheral portion of the mask layer so that the second section of the image can be viewed in reflection against the peripheral portion of the mask layer. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A process for producing a slide, the process comprising:
-
providing a slide blank comprising a support;
a mask layer having a substantially transparent central portion and a non-transparent peripheral portion surrounding the central portion; and
an imageable layer which is not substantially sensitive to visible radiation but is imageable by exposure to actinic radiation to form an image which can be viewed in transmission, the support, mask layer and imageable layer being secured together so that the support and the imageable layer extend across essentially the entire transparent central portion of the mask layer, at least the portion of the support adjacent the central portion of the mask layer being substantially transparent; andexposing at least part of the imageable layer of the slide blank to actinic radiation and thereby forming in the imageable layer an image which can be viewed in transmission, thereby producing a slide. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36)

37. A slide blank in the form of a flat, substantially square lamina having two substantially planar major surfaces on opposed sides thereof, the lamina having an edge length of from about 40 to about 70 mm and a thickness of from about 0.8 to about 1.7 mm, the slide blank comprising:
-
a substantially rigid support; a mask layer having a substantially transparent central portion and a non-transparent peripheral portion surrounding the central portion; and
,an imageable layer which is not substantially sensitive to visible radiation but is imageable to form an image which can be viewed in transmission, the support, mask layer and imageable layer being of substantially the same dimensions in the plane of the lamina and being secured together so that the support and the imageable layer extend across substantially the whole area of the support, at least the portion of the support adjacent the central portion of the mask layer being substantially transparent.

38. A slide in the form of a flat, substantially square lamina having two substantially planar major surfaces on opposed sides thereof, the lamina having an edge length of from about 40 to about 70 mm and a thickness of from about 0.8 to about 1.7 mm, the slide comprising:
-
a substantially rigid support; a mask layer having a substantially transparent central portion and a non-transparent peripheral portion surrounding the central portion; and
,an image layer bearing an image which can be viewed in transmission, the support, mask layer and image layer being of substantially the same dimensions in the plane of the lamina and being secured together so that the support and the image layer extend across substantially the whole area of the support, at least the portion of the support adjacent the central portion of the mask layer being substantially transparent, so that the image can be projected by passing light through the image layer, the transparent central portion of the mask layer and the support.

40. A process for producing a slide, the process comprising:
-
providing a slide blank comprising a support;
a mask layer having a substantially transparent central portion and a non-transparent peripheral portion surrounding the central portion; and
an imageable layer which is not substantially sensitive to visible radiation but is imageable to form an image which can be viewed in transmission, the support, mask layer and imageable layer being secured together so that the support and the imageable layer extend across essentially the entire transparent central portion of the mask layer, at least the portion of the support adjacent the central portion of the mask layer being substantially transparent, the imageable layer further extending across at least part of the peripheral portion of the mask layer; andforming in the portion of the imageable layer lying adjacent the central portion of the mask layer an image which can be viewed in transmission through the support and the transparent central portion of the mask layer, and forming in the portion of the imageable layer lying adjacent the peripheral portion of the mask layer indicia which can be viewed in reflection against the mask layer, thereby producing a slide.
