Claims
- 1. A method for making a lithographic image on a surface, comprising the steps of:
- (a) coating at least a portion of a surface of an article with a composition comprising a random copolymer of an isoolefin of 4 to 7 carbon atoms and para-alkylstyrene comonomer, said isoolefin comprising 10 to 99.5 weight % of said copolymer and said para-alkylstyrene comprising 0.5 to 90 weight % of said copolymer, wherein about 0.5 to 55 weight % of said copolymer comprises para-alkylstyrene monomers having a photoinitiator substituted on the pendent alkyl group, said copolymer having a substantially homogenous compositional distribution;
- (b) selectively exposing said surface to gamma, UV, thereby forming a crosslinked latent electron beam, visible, or microwave radiation to crosslink the copolymer lithographic image,
- (c) removing the uncrosslinked copolymer to develop the lithographic image.
- 2. The method of claim 1, wherein said removing step comprises washing said surface with a solvent.
- 3. The method of claim 1, further comprising etching said surface to transfer said image into said surface.
- 4. The method of claim 3, further comprising the step of removing said crosslinked coating from etched surface.
- 5. The method of claim 4, wherein said removing step comprises a chemical or plasma treatment of said coating.
- 6. The method of claim 1, wherein said coating comprises depositing a solution of said polymer on said surface and removing said solvent to leave a film of said polymer on said surface.
- 7. The method of claim 1, wherein said coating comprises depositing a hot melt of said polymer on said surface.
- 8. The method of claim 1, wherein said article comprises metal, paper, wood, plastic, textile, glass, ceramic, graphite, or composites thereof.
