    摘要： Imagable articles comprising positive working polymeric resins coating onto substrates are given a heat treatment comprising their controlled slow cooling from an elevated temperature. The imagable articles include precursors for lithographic printing plates and for printed circuits. The controlled slow cooling improves the development characteristics of the coatings after an imaging step.

    摘要： 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.

    摘要： An apparatus and method for providing substantially intimate rolling contact between a portion of a donor sheet and a portion of an acceptor element in a laser-induced thermal transfer printer comprises a rotatably mounted cylindrical drum, an acceptor element affixed to and supported by the cylindrical drum, a rotatably mounted dispensing roller for dispensing a donor sheet, and a rotatably mounted receiving roller for receiving the donor sheet, so that the donor sheet is extended between the dispensing roller and the receiving roller. A plurality of rotatably mounted contact rollers configured to bring a portion of the donor sheet extended between the dispensing roller and the receiving roller into contact with a portion of the acceptor element is also included.
