Abstract: A flexible and nonbrittle negative-working photoresist composition comprises a polymeric binder, a photoinitiator composition, and a polymerizable cyclohexyleneoxyalkyl acrylate monomer characterized by the structural formula: ##STR1## wherein R is H or CH.sub.3,a is an integer of from 1 to 10 andb is 1 or 2.

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: 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: 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.
