Abstract
The present invention provides compositions and methods of ink jetting oleophilic images onto a substrate. The composition includes an oleophilic polymer having polar moieties that is soluble in an organic carrier and adheres to a substrate. Compositions of the present invention may be used to form oleophilic image areas for lithographic printing.
Claims44
A method of preparing a printing plate comprising:
- providing a substrate;
- and
- imagewise applying onto the substrate an ink jettable composition consisting essentially of an oleophilic polymer in a substantially organic solvent and optional nonvolatile components or additives, wherein the oleophilic polymer has polar moieties with the exception of nitrogen-containing heterocyclic moieties;
- and
- adhering the oleophilic polymer to the substrate.

A method of forming an image on a substrate comprising:
- providing a substrate;
- and
- imagewise applying to the substrate an ink jettable composition consisting essentially of an oleophilic polymer having polar moieties in a substantially organic solvent and optional nonvolatile components or additives, wherein the oleophilic polymer is free of nitrogen-containing heterocyclic moieties.
A printing plate comprising:
- a substrate;
- and
- an oleophilic image area adhered to the substrate, wherein the oleophilic image area consists essentially of an ink jettable oleophilic polymer and optional nonvolatile components or additives, wherein the oleophilic polymer has polar moieties with the exception of nitrogen-containing heterocyclic moieties.
