Abstract: A laminate, adapted for manufacturing frames of metal beam leads that are bonded to integrated circuit chips, comprises(a) a flexible metal strip,(b) a layer of a first resist adhered to one surface of the metal strip, and(c) a layer of a second resist adhered to the opposite surface of the metal strip,the second resist being a negative-working resist comprising(1) a polymeric binder,(2) a photopolymerizable monomer mixture, and(3) a photoinitiator composition. The negative-working resist exhibits excellent flexibility and adhesion to the metal and superior performance during high temperature processing, whereby it serves effectively as a support for the beam leads.

Abstract: Substantially amorphous polyesters containing ionic moieties are useful to uniformly disperse particulate pigments in dispersions, image-forming compositions and elements, e.g. lithographic compositions and elements. Such polyesters reduce pigment agglomerations and improve dispersion stability in such dispersions and compositions and coatings prepared therefrom.

Abstract: Disclosed herein are heat-activatable adhesive compositions containing a water-dispersible polyester which comprisesA. an acid component comprising:(1) from about 8 to about 16 mole percent of units derived from at least one dicarboxylic acid having an ionic iminosulfonyl moiety containing a monovalent cation as an imino nitrogen substituent;(2) from about 40 to about 70 mole percent of units derived from at least one dicarboxylic acid selected from the group consisting of aliphatic dicarboxylic acids having the formula HOOC--(CH.sub.2).sub.

Abstract: Photographic elements, two-sheet diffusion transfer assemblages containing such elements, and dye image-receiving elements are described. The photographic element comprises a support, a neutralizing layer, a timing layer, a vinylidene chloride polymeric layer, a polymeric primer layer, and at least one silver halide emulsion layer having a dye image-providing material associated therewith. The vinylidene chloride polymeric layer and the polymeric primer layer prevent unwanted transfer of portions of the emulsion layer to a receiver when the receiver and photographic element are peeled apart. The polymeric primer layer can be either a particular ionic vinyl polymer or a particular ionic polyester.

Abstract: An intercom arrangement in a key telephone system is disclosed that permits the answering of intercom calls "hands-free" at a called station. Intercom calls are originated in the standard manner, with the calling party lifting the handset at a station and selecting an idle intercom line. After the calling party depresses a direct station selection button that corresponds to the called station, a hands-free answer unit located in the called station automatically connects to the proper intercom line and provides an alerting tone to both the calling and called station. The calling party is then able to converse with the called party by alternately activating a loudspeaker and a microphone contained in the called station.

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-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.
