Abstract
A method for preparing a lithographic plate which can react with an imaging fluid to form an image, including providing a hydrophilic support; forming a fluid-receiving layer that includes a water-soluble material which is chemically reactive with the imaging fluid; imagewise applying the imaging fluid to the fluid-receiving layer; and drying or curing the applied fluid to form an image in the fluid-receiving layer.
Claims7
A method for preparing a lithographic plate which can react with an imaging fluid to form an image, comprising the steps of:
- a) providing a hydrophilic support;
- b) forming a fluid-receiving layer that includes a water-soluble epoxy resin substantially free from metal ions which is chemically reactive with the imaging fluid;
- c) imagewise applying the imaging fluid to the fluid-receiving layer;
- and
- d) drying or curing the applied fluid to form an image in the fluid-receiving layer.
A lithographic plate which can react with an imaging fluid to form an image, comprising:
- a) a hydrophilic support;
- and
- b) a fluid-receiving layer that includes a water-soluble epoxy resin substantially free from metal ions which is chemically reactive with the imaging fluid so that after imagewise applying the imaging fluid to the fluid-receiving layer, and drying or curing the applied fluid an image will be formed in the fluid-receiving layer.
A method for preparing a lithographic plate which can react with an imaging fluid to form an image, comprising the steps of:
- a) providing a hydrophilic support;
- b) forming a fluid-receiving layer that includes a water-soluble epoxy resin substantially free from metal ions which is chemically reactive with the imaging fluid;
- c) imagewise applying the imaging fluid to the fluid-receiving layer and such imaging fluid including a polymer including aromatic heterocyclic nitrogen groups;
- and
- d) drying or curing the applied fluid to form an image in the fluid-receiving layer.
