Abstract: Rubber compositions are disclosed which are formulated to provide high modulus at 100% and strong adhesion to metal. Chlorinated polyethylene rubber and/or its derivative reformed with maleic anhydride is blended with specified amounts of a 2-mercaptobenzothiazole dicyclohexylamine salt, trithiocyanuric acid and sufur such that formulae (1) and (2) are met ##EQU1## where phr is defined as the amount in parts of the component per hundred parts of component (A) or component (B) or both.
Abstract: A coated photosensitive material on a support comprising a layer of polyamic acids and polyamic acid aryl esters derived from tetracarboxylic acids or aminodicarboxylic acids containing a benzophenone structural unit and aromatic diamines which are substituted in both ortho-positions by at least one amino group. The material is autophotocrosslinkable and is suitable for producing protective coatings and photographic images, with corresponding polyimides being formed after irradiation by a thermal aftertreatment.
