    Abstract: Ablation-type printing plates having increased shelf-life are produced using a melamine resin free of water prior to use. A representative production sequence includes providing a substrate having an oleophilic surface; coating, over the substrate, an oleophilic resin composition having (A) a resin phase consisting essentially of a melamine resin substantially free of water and a resole resin, the resole resin being present in an amount ranging from 0% to 28% by weight of dry film, (B) a near-IR absorber dispersed within the resin phase, and (C) a sulfonic acid catalyst dispersed within the resin phase and being present in an amount ranging from 0.7% to 1.6% by weight of dry film; curing the resin composition to produce a dry film; following resin curing, coating an oleophobic polymer composition over the cured resin composition; and curing the oleophobic polymer composition.

    Abstract: A novel ink formulation, especially useful in Driography printing, is disclosed. The ink formulation comprises a basic planographic printing ink vehicle, a pigment, a modifying varnish and a flow control agent to provide an ink, especially suitable for use in Driography, which exhibits desirable hangling-viscosities under ambient conditions, improved rheological properties under severe press-operating conditions, and provides printings having sharp delineation, fidelity and excellent reproducibility in depth of color tones in long press runs. The basic printing ink vehicle may be a vehicle designed for either sheet-fed or heat-set printing systems. The novel ink formulation is designed to have a high viscosity and avoid becoming pseudoplastic in its behavior at higher press temperatures, which generally can range from about 85.degree. F. to 125.degree. F., and preferably, avoids becoming pseudoplastic at temperatures up to about 140.degree. F. or more.

    Abstract: Methods of imaging and printing are provided whereby a transparent self-supporting substrate is coated with a transparent abhesive polymer and an image formed by inking said polymer and simultaneously subjecting said polymer to electromagnetic radiation to reduce the cohesive force of said ink or increase the adhesive force so as to selectively deposit ink in image configuration on said adhesive polymer, and transferring said inked image to a receiver sheet.

    Abstract: Presensitized planographic printing plate for use in dry planography. A positive acting plate having a flexible base and a relatively thick (0.02 to 2.00 mil) silicone rubber layer, overlying a photo-polymerizable and photoadhesive-layer. Upon exposure to light through a positive transparency, the photoadhesive layer in the exposed non-image area polymerizes and adheres firmly to the thick silicone rubber overlayer, but the photoadhesive layer in the unexposed image area remains nonadhesive to the silicone overlayer. Following the exposure, the surface of the plate is treated with developing liquid capable of swelling silicone rubber. The thick silicone rubber layer in the unexposed image area is easily removed, exposing a sharp image of oleophilic photoadhesive layer underlying the removed silicone layer, while the silicone rubber layer in the exposed background area remains bound to the photoadhesive underlayer. The exposed surface of the photoadhesive layer accepts ink from inking rollers, while the silicone rubber background area does not remove ink from the rollers, and thus remains ink-free.
