  • Photoresist
    Patent number: 5286611
    Abstract: Photocurable and solvent-developable compositions based on photopolymerizable (meth)acrylates, a photoinitiator for (meth)acrylates, an organic polymeric binder which comprises free carboxyl groups and has an acid number of at least 60, a blocked polyisocyanate crosslinking agent which has a cleavage temperature of at least 100.degree. C., and an inert solvent in an amount such that the photocurable composition is pourable, are described.
    Type: Grant
    Filed: July 20, 1992
    Date of Patent: February 15, 1994
    Assignee: Ciba-Geigy Corporation

  • Curable composition and the use thereof
    Patent number: 5073476
    Abstract: Iron (II)-aromatic compound complexes mixed with electron acceptors as an oxidizing agent are suitable initiators for the polymerization by irradiation of organic material which can be polymerized by cations and/or free radicals. The composition composed of the polymerizable material and of the initiator mixture is suitable for the production of protective coatings and can be used as a photographic recording material.
