    摘要： An imaging process uses an imaging medium comprising a polymer having a plurality of first groups. This polymer is imagewise contacted with an imaging reagent comprising a plurality of second groups, thus causing, in the areas of the medium exposed to the imaging reagent, the second groups to react with the first groups and form a colored material, and thereby forming an image on the imaging medium. One of the first and second groups comprises a benzotriazinone or benzothiatriazine-4,4-dioxide benzotriazinone moiety and the other comprises a naphthol or a pyrazalone moiety.

    摘要： Crosslinked sulfonated triblock copolymers exhibit lower methanol permeability and good physical strength relative to the perfluorinated proton conductive membranes typically used in Direct Methanol Fuel Cells. Examples of triblock copolymers that can be used as fuel cell membranes include SEBS, SIBS, and SEPS. The chemically cross-linked and sulfonated SIBS, SEBS, and SEPS exhibit lower swelling and tolerate higher sulfonation levels than the un-cross-linked counterparts. These copolymers are easily sulfonated using known procedures and can be manufactured at a fraction of the cost of the typical perfluorinated proton conductive membranes.

    摘要： A membrane electrode assembly includes a polymer electrolyte membrane sandwiched between an anode catalyst layer and a cathode catalyst layer. The area of the anode catalyst layer is less than the area of the cathode catalyst layer. The larger cathode catalyst layer is believed to increase collection of protons from the anode reaction, reduce the corrosive effect of the highly acidic solvated protons in the polymer electrolyte membrane, and allow for small misalignments of the layers during construction of the assembly.

    摘要： An image-receiving element for use in photographic and photothermographic diffusion transfer film units of the type wherein the image-receiving element is designed to be removed or "peeled-apart" from a photosensitive element following exposure and processing. The present image-receiving element comprises in sequence, a support, an image-receiving layer, and a strip-coat layer. The strip-coat layer serves to facilitate separation of the image-receiving layer from a photosensitive element after processing. The strip-coat layer comprises a copolymer including: 1) at least about 50% by weight of monomer units, the same or different, derived from an ethylenically unsaturated carboxylic acid or salt thereof, 2) at least about 15% by weight of monomer units of vinyl pyrrolidone, and 3) at least about 5% by weight of monomer units, the same or different, represented by the formula: ##STR1## wherein R.sub.1 of each monomer unit is independently selected from: hydrogen, a substituted or unsubstituted alkyl having 1 to 4 carbon atoms, cyano, and halogen; X of each monomer unit is independently selected from --NH-- or --O--; and R.sub.2 of each monomer unit is independently selected from a hydroxy substituted alkyl group.
