  • Publication number: 20160064769
    Abstract: A system for fabricating an electrical storage cell including an imaging head for applying collimated ultraviolet radiation on a masked positioned on top of a photopolymer substrate, wherein the patterned mask comprises masked regions and unmasked regions; wherein areas of the photopolymer underneath of the unmasked regions are solidified or cross linked and areas of the photopolymer underneath the masked are not solidified or cross linked; a developer for developing the imaged substrate; water jets for cleaning solidified or cross linked material from the substrate to form perforated holes; a deposition device for forming a thin film over the substrate surface area so as to define an anode; a deposition device for forming solid electrolyte disposed over the anode; and a deposition device for forming a cathode by depositing a thin film over the perforated holes.

  • Patent number: 8940474
    Abstract: A silicate-free alkaline aqueous developer composition has a pH of at least 12 and comprises a hydroxide alkali agent, a metal cation M2+ selected from barium, calcium, strontium, and zinc cations, a chelating agent for the metal cation, and an alkali metal salt that is different than the other components. These developer compositions can be used to process imaged positive-working lithographic printing plate precursors to prepare lithographic printing plates.

  • Patent number: 8939080
    Abstract: A method is used to prepare lithographic printing plates by developing positive-working lithographic printing plate precursor that has a single imageable layer that comprises a polymer binder having recurring units represented by Structure (Ib) below: wherein the recurring units of Structure (Ib) are present in an amount of at least 25 and up to and including 60 mol %, all based on total recurring units in the polymer binder, and R2 is a substituted or unsubstituted hydroxyaryl group in which the hydroxyl group is ortho to the ester linkage, to form exposed and non-exposed regions in the imageable layer. The resulting imaged lithographic printing plate is developed using a silicate-free developer composition having a pH of at least 12 and comprising at least 0.001 gram-atom/kg of a metal cation M2+ selected from the group consisting of barium, calcium, strontium, and zinc cations.

  • Patent number: 8530143
    Abstract: A silicate-free alkaline aqueous developer composition has a pH of at least 12 and comprises a metal cation M2+ selected from barium, calcium, strontium, and zinc cations, and a chelating agent that has a complex formation constant (log K) for the metal cation of at least 3.5 and less than or equal to 4.5, and a log K for aluminum ion that is 7 or less. This developer composition can be used to process positive-working lithographic printing plate precursors to provide lithographic printing plates.
