A photosensitive element having an infrared imageable layer, and a process for making a relief image from such an element are disclosed.

Process and element for making a relief image using an IR sensitive layer

An element for use in a laser induced ablative transfer process, said element comprising a support bearing on a first surface thereof at least one coating comprising (i) a non-sublimable imageable component, (ii) a laser radiation absorbing component, (iii) a particular filler having an average particle size (S), and (iv) optionally a binder, wherein the non-sublimable imageable component and the laser radiation absorbing component can be the same or different; wherein the total thickness of all coatings present on the first surface is T and further wherein S.gtoreq.2T is described.

Element and process for laser-induced ablative transfer utilizing

These is disclosed donor elements for laser-induced thermal imaging processes containing infra-red absorbing squarylium dyes of the following structure: ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, and R.sup.4 are each independently alkyl groups of from one to eight carbon atoms.

Donor element for thermal imaging containing infra-red absorbing

An improved X-ray intensifying screen element containing a topcoat layer comprising an acrylonitrile-styrene copolymer optionally mixed with a carboxylated acrylic polymer and an active, phosphor layer having an adhesion promoting amount of a soluble, inorganic salt as described. The improved element exhibits strong adhesion between the topcoat and active layers and is eminently suitable for the rough handling encountered when these elements are used in autochangers and the like.
