  • Patent number: 9890301
    Abstract: A pressure-sensitive adhesive is provided that is a dried product of a latex composition, which is formed from an emulsion composition. The latex composition and the emulsion composition are also provided. The emulsion composition has droplets that contain various monomers plus a (meth)acrylate polymer dissolved in the monomers. Additionally, an article containing a layer of the pressure-sensitive adhesive and a method of forming the pressure-sensitive adhesive are provided. The pressure-sensitive adhesives often have both high peel adhesion and high shear strength (i.e., high cohesive strength or high shear holding power).

  • Patent number: 7514206
    Abstract: Thermally developable materials including photothermographic and thermographic materials have a buried conductive backside layer comprising one or more binder polymers in which are dispersed each of at least two types of conductive materials: (1) nanoparticles of one or more conductive metal compounds, and (2) one or more organic solvent soluble inorganic alkali metal salt antistatic compounds. These buried conductive backside coatings provide conductivity that is affected minimally by humidity.
