Forming a color filter by vacuum depositing alternating layers of SiO.sub.2 and TiO.sub.2 at a temperature of less than 150.degree. C.

Patterned dichroic filters for solid state electronic image sensors

A lithographic lift-off process includes coating a layer of positive resist material using a dynamic dispense on top of a preexisting layer of a different positive resist material. Thereafter, patternwise exposing both layers simultaneously and developing the exposed portions of both layers for a sufficient time to provide openings in the resists wherein the dynamic dispense layer overhangs the preexisting layer.

Lift-off process for patterning dichroic filters

A method of forming a color filter array which includes forming only a single image mordant layer on a device and then exposing the mordant to a pattern representing an array of filter elements and developing areas of the mordant to provide separated filter elements. These filter elements are then selectively dyed different colors.

Method of making color filter arrays

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.

Color filter array containing a photocrosslinked polymeric mordant

A photographically negative-working patternable mordant composition is disclosed containing a photocrosslinkable polymer comprised of, for providing both mordanting and crosslinking sites, repeating units of the formula: ##STR1## wherein Ar is an aromatic linking group,

Photographic element and patternable mordant composition

Catalysts for the conversion of synthesis gas to linear alcohols and aldehydes are disclosed. The catalysts are mixed oxides of copper, iron and either chromium or aluminum and wherein said mixed oxide has a delafossite type of crystal lattice structure.

Delafossite mixed metal oxide catalysts and method for their preparation

Disclosed herein are heat-activatable adhesive compositions comprising a water-soluble condensation polymer which is characterized by having a glycol component comprising one or more diols, preferably one of which is 1,4-bis(2-hydroxyethoxy)cyclohexane; and an acid component comprising greater than 15 and up to about 35 mole percent of at least one diacid or diester monomer having an iminodisulfonyl salt moiety, and from about 65 to about 85 mole percent of one or more other diacids or diesters. These adhesives are further characterized as having high bonding strengths at temperatures above 50.degree. C. They have been found useful in a variety of photographic materials, and particularly in image transfer film units.
