  • Current collector having a conductive primer layer
    Patent number: 5478676
    Abstract: A current collector which uses a conductive primer layer under an electrode layer to improve the contact and adhesion of the electrode layer to a supporting member, wherein the conductive primer layer is composed of a polymeric material having pendant carboxylic acid groups crosslinked with a multifunctional crosslinking agent, and a conductive filler. The current collector may be used inter alia for making batteries.

  • Overcoats for diazo-containing layers with chemicals and abrasion resistance
    Patent number: 5382495
    Abstract: It has surprisingly been found that a protective coating composition for diazo-containing materials can be prepared from a cellulose ester, a hydroxylated resin, a crosslinking agent, microcrystalline silica and an acid catalyst. The coating compositions of the invention provide improved protection for diazo-containing materials from physical and chemical damage. The protective coating compositions of the invention are particularly effective for protecting the diazo-containing materials from chemical attack from solvents. The invention further relates to photographic elements and phototools provided with the protective coating composition and a method for providing the coating composition.
