Abstract: An image sensor which includes an integral color filter array and a method of making such sensor is disclosed. The sensor includes a semiconductor substrate having an overlying support layer with an optically planar surface, a plurality of spaced image pixels formed in the substrate; and an array of contiguous color filter elements overlying the planar surface whose top surfaces are coplanar and which have no overlap of color filter material between adjacent color filter elements.

Abstract: 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-hydroxy-ethoxy)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.
