Abstract: A heat-resistant anti-static pressure-sensitive adhesive tape comprising a substrate having coated thereon an acrylic microparticulate adhesive having an average diameter of at least about 1 micrometer, wherein the microparticles have a surface bearing thereon a conductive material formed from a polymer electrolyte base polymer, and at least one ionic salt selected from the group consisting of salts of alkali metals and salts of alkaline earth metals, said adhesive being adhered to said substrate by means of a primer, said primer comprising at least one phenolic resin and at least one rubbery compound, said adhesive tape being capable of surviving immersion in molten solder for at least about 5 seconds.

Abstract: A water-resistant, anti-static pressure-sensitive adhesive tape suitable for use as a wafer dicing tape comprising a flexible substrate having opposing surfaces, at least one surface bearing thereon a removable, aziridine-crosslinked microparticulate adhesive comprised of microparticles having a surface bearing thereon an ionic conductive material formed from a polymer electrolyte base polymer, and at least one ionic salt selected from the group consisting of salts of alkali metals and salts of alkaline earth metals, wherein said microparticles have an average diameter of at least about 1 micrometer, said adhesive having an adhesion to steel of from about 0.5 Newtons/100 mm (N/100 mm) to about 10 N/100 mm.

Abstract: Conductive, polymeric, inherently tacky, solvent-insoluble, solvent-dispersible, elastomeric, pressure-sensitive adhesive microparticles having an average diameter of at least about 1 micrometer, said microparticles having an ionic conductive material present on said surface, and anti-static pressure-sensitive adhesive tapes made therefrom.

Abstract: Flexible sheet materials and envelopes are described which are useful for packaging electronic components. The sheet material includes an electrically insulating film with a conductive layer on the upper surface and an antistatic layer carried by the lower surface The antistatic layer includes a fluoroaliphaticsulfonamide polyether compound. Optionally a tie layer may be included between the film and the antistatic layer.

Abstract: A thermally developable photosensitive material containing (a) at least one organic silver compound, (b) at least one reducing agent, for said organic silver compound, (c) at least one photosensitive silver halide, and (d) at least one indan or tetralin derivative having at least two carboxyl groups. The indan and tetralin derivatives operate to suppress thermal fog.

Abstract: Thermally developable light sensitive material containing a light sensitive silver halide, an oxidizing agent, a reducing agent, and a combination of 2-(hydroxymethyl)-1(2H)-phthalazinone as a toning agent precursor and certain polycarboxylic acids or derivatives thereof as a catalyst for said toning agent precursor. Upon heat development of the exposed photothermographic material, the 2-(hydroxymethyl)-1(2H)-phthalazinone decomposes to form phthalazinone. The thus-formed phthalazinone acts as a toning agent for the light exposed silver halide.

Abstract: The addition of certain classes of aromatic nitrogen containing compounds to photothermographic emulsions stabilizes the background density of the imaged film and/or increases the speed of the emulsion.

Abstract: Photothermographic materials may be stabilized by inclusion of compounds having terminal 1,1,1-tri bromoethoxy or 1,1,1-di bromochloroethoxy type groups.
