    摘要： A process for generation of acid uses a medium comprising a first acid-generating component capable of generating a first acid, and a secondary acid generator, this secondary acid generator being capable of thermal decomposition to form a secondary acid, the thermal decomposition of the secondary acid generator being catalyzed by the first acid. At least part of the medium is exposed to so as to cause formation of the first acid from the first acid-generating component; and the medium is then heated to cause, in the exposed part of the medium, acid-catalyzed thermal decomposition of the secondary acid generator and formation of the secondary acid. The secondary acid generator has a first site bearing a first leaving group and a second site bearing a second leaving group, the first leaving group being capable of protonation by the first acid, with expulsion of the first leaving group to form a cation which electrophilically adds to an unsaturated reagent bearing a proton at the site of addition and a proton-containing nucleophilic grouping at an adjacent site, following which said proton on the reagent is lost and the second leaving group is displaced by said nucleophilic grouping, the second leaving group, in combination with a proton, forming the secondary acid. Preferred variants of the process are of the types described in U.S. Pat. Nos. 5,286,612; 5,334,489; 5,395,736; 5,441,850 and 5,453,345.

    摘要： 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.

    摘要： 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.

At least part of the medium is exposed to so as to cause formation of the first acid from the first acid-generating component; and the medium is then heated to cause, in the exposed part of the medium, acid-catalyzed thermal decomposition of the secondary acid generator and formation of the secondary acid. The secondary acid generator has a first site bearing a first leaving group and a second site bearing a second leaving group, the first leaving group being capable of protonation by the first acid, with expulsion of the first leaving group, followed by loss of a proton from the secondary acid generator to form an unstable intermediate, which then fragments with loss of the second leaving group, accompanied by either (a) loss of a second proton; or (b) addition of a proton-containing nucleophile, followed by loss of a proton, the second leaving group, in combination with a proton, forming the secondary acid. Preferred variants of the process are of the types described in U.S. Pat. Nos. 5,286,612; 5,334,489; 5,395,736; 5,441,850 and 5,453,345.
