An antistatic adhesive article which comprises an adhesive layer and utilizes vanadium oxide to impart antistatic properties to the article. The article is preferably an adhesive tape or sheet. The adhesive may be pressure sensitive or non-pressure sensitive. The vanadium oxide may be incorporated into or onto the tape from an aqueous dispersion.

A thermal transfer system for transferring material in an imagewise manner by means of thermal transfer printing from a donor element to an image receiving element is used to prepare printing plates. In one construction, a donor element, which is prepared by coating a photoinitiator (and optionally a sensitizer) in a binder on a backing material, is used with an image receiving element, which is prepared by coating a photopolymer (and optionally a sensitizer) on a substrate having a microporous hydrophilic crosslinked silicated surface. In an alternative construction, a donor element, which is prepared by coating a sensitizer in a binder on a backing material, is used with an image receiving element, which is prepared by coating a photopolymer and photoinitiator on a substrate having a microporous hydrophilic crosslinked silicated surface. In yet another construction, a donor element, prepared by coating a thermal transfer layer containing a photopolymer, a photoinitiator and/or a sensitizer on a backing material, is used with an image receiving element having a microporous hydrophilic crosslinked silicated surface.

An image deletion fluid for printing plates which use a silver image as an ink-receptive area. The deletion fluid comprises iodine and an effective excess of iodide ion, which form a triiodide complex, and a hydrophilic-matrix-forming agent. In a preferred embodiment, the deletion fluid further comprises an organic, preferably polar, solvent. The deletion fluid is applied to the surface of the plate, rubbed briefly and allowed to dry there, with no removal or rinsing away of the deletion fluid or by-products required.

A coating composition which imparts anti-reflective and anti-fog properties to substrates coated therewith. The coating composition utilizes an inorganic metal oxide in combination with particular anionic surfactants. The coating compositions are particularly useful in the manufacture of disposable surgical masks and face shields.

A photolithographic receptor sheet for silver diffusion transfer imaging comprising a support with a hydrophilic layer thereon consisting essentially of colloidal silica and a defined dry hydrophilic powder, and a catalytic silver precipitating nuclei layer thereover. The imaged construction is useful as a lithographic printing plate.

An abrasive article (i. e. , a coated abrasive article or a three-dimensional, low density abrasive article) having a sufficient amount of vanadium oxide incorporated therein to provide having a reduced tendency to buildup static electricity during the abrading of a workpiece. Preferably, the abrasive article further comprises a compatible binder (preferably, a sulfonated polymer) to aid in securing the vanadium oxide to the abrasive article. In another aspect, a method of making the same is taught.
