The present invention relates to an antistatic article comprising a substrate or support having thereon at least one antistatic layer, wherein the antistatic layer comprises a conductive material having areas of patterned coverage.

Transparent invisible conductive grid

A solid state image sensor is described which includes a planarizing layer incorporated into a means of color separation. The planarizing layer has been found to provide a smooth, uniform surface for coating and adhesion of a color separator within the active device area. The planarizing layer remains on the completed device and is patterned to permit access to bonding pads. Negative photoresist materials, photoinitiated polymerization imaging systems and positive imaging systems may be selected for use as the planarizing layer.

Stabilization of a patterned planarizing layer for solid state imagers

A thermal dye transfer assemblage comprising: (a) a dye-donor element comprising a support having thereon a dye layer comprising a dye dispersed in a polymeric binder, the dye being substituted with a reactive primary or secondary aliphatic amino group, and (b) a dye-receiving element comprising a support having thereon a dye image-receiving layer, the dye-receiving element being in a superposed relationship with the dye-donor element so that the dye layer is in contact with the dye image-receiving layer, the dye image-receiving layer comprising a polymer containing a pendant alkyl acrylamidoglycolate alkyl ether group.

Thermal dye transfer system with receiver containing alkyl

A dye-receiving element for thermal dye transfer includes a support having on one side thereof a dye image-receiving layer. Receiving elements of the invention are characterized in that the dye image-receiving layer or an overcoat layer thereon comprises a polyester comprising recurring dibasic acid derived units and diol derived units, at least 50 mole % of the dibasic acid derived units comprising dicarboxylic acid derived units containing an alicyclic ring within two carbon atoms of each carboxyl group of the corresponding dicarboxylic acid, and at least 30 mole % of the diol derived units containing an aromatic ring not immediately adjacent to each hydroxyl group of the corresponding diol or an alicyclic ring.

Thermal dye transfer receiving element with polyester dye image-receiving

A dye-receiving element for thermal dye transfer includes a support having on one side thereof a dye image-receiving layer. Receiving elements of the invention are characterized in that the dye image-receiving layer comprises a water dispersible polyester comprising recurring dibasic acid derived units and diol derived units, at least 50 mole % of the dibasic acid derived units comprising dicarboxylic acid derived units containing an alicyclic ring within two carbon atoms of each carboxyl group of the corresponding dicarboxylic acid, and at least 2.5 mole % of the dibasic acid derived units and diol derived units combined comprising ionic monomer derived units containing an ionic group.

Thermal dye transfer receiving element with aqueous dispersible

A dye-receiving element for thermal dye transfer includes a support having on one side thereof a dye image-receiving layer. Receiving elements of the invention are characterized in that the dye image-receiving layer comprises a miscible blend of an unmodified bisphenol-A polycarbonate having a number molecular weight of at least about 25,000 and a polyester comprising recurring dibasic acid derived units and diol derived units, at least 50 mole % of the dibasic acid derived units comprising dicarboxylic acid derived units containing an alicyclic ring within two carbon atoms of each carboxyl group of the corresponding dicarboxylic acid, and at least 30 mole % of the diol derived units containing an aromatic ring not immediately adjacent to each hydroxyl group of the corresponding diol or an alicyclic ring.

Thermal dye transfer receiving element with polyester/polycarbonate

A copolyester is synthesized by reacting a dialkyl ester of an aromatic dicarboxylic acid (e.g., dimethyl terephthalate) with ethylene glycol, low molecular weight poly(ethylene glycol) and a salt of a sulfonic acid-substituted aromatic dicarboxylate (e.g., sodium sulfoisophthalic acid) simultaneously in a first stage reaction in the presence of a phosphite or phosphate stabilizer. The intermediate product of the first stage is further reacted in a second stage in the presence of a polycondensation catalyst to obtain a random copolyester of the desired molecular weight. The copolyester is extruded to form a film which, after orientation and heat setting, has excellent clarity and is useful as a photographic film support. Aqueous processing of the film relaxes any core set or curl.

A method for producing high resolution patterned resist images having excellent etch resistance and superior thermal and dimensional stability comprises the steps of:

Bilayer lithographic process

A color filter array is disclosed containing interlaid sets of laterally displaced filters comprised of a polymeric matrix and at least one dye. At least one of the sets of filters is comprised of an anionic dye and a cationic polymeric mordant having crosslinking repeating units containing two quaternary ammonium mordanting moieties and a photogenerated ethylenic crosslinking moiety.

Photographic element and patternable mordant composition

Positive-working photoresist elements are protected against reflection of activating radiation from the substrate by incorporation of certain butadienyl dyes in a photoresist layer, an anti-reflective layer or a planarizing layer. These dyes have superior resistance to thermal degradation or volatilization at temperatures of as high as 200.degree. C. or more. The dyes also exhibit good solubility in solvents commonly employed in processing semiconductor devices, thus permitting the dyes to be incorporated in photoresist elements in an amount sufficient to prevent resist image distortion caused by backscattered or reflected light.
