Abstract
A method of manufacturing conductive patterns includes the steps of a) printing and curing UV curable inkjet to define a cured inkjet ink pattern on a metal sheet bonded to a non-conductive substrate; b) etching the metal sheet not covered by the cured ink pattern to expose the non-conductive substrate; and c) applying an alkaline solution to dissolve the cured inkjet ink pattern within 5 minutes.

1-15. (canceled)
A method of manufacturing a conductive pattern comprising the steps of:
- printing and curing a UV curable inkjet ink to define a cured inkjet ink pattern on a metal sheet bonded to a non-conductive substrate;
- etching the metal sheet not covered by the cured inkjet ink pattern to expose the non-conductive substrate;
- and
- dissolving the cured inkjet ink pattern within 5 minutes with an alkaline solution.
1 more element
A UV curable inkjet ink comprising:
- one or more photoinitiators;
- a colorant that decolorizes at a pH of more than 10;
- one or more hydrolyzable polyfunctional monomers or oligomers including at least one alkali hydrolyzable group located in the atomic chain between two polymerizable groups of the one or more hydrolyzable polyfunctional monomers or oligomers;
- and
- one or more water absorption controlling monomers including a monofunctional or difunctional monomer containing at least one functional group selected from the group consisting of a hydroxyl group, an ethylene oxide or oligo-ethylene oxide group, a tertiary amine group, an acidic group having a pKa not lower than 3, and a five to seven membered aromatic or non-aromatic heterocyclic group.
