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.
