Abstract
The present invention is directed to processes for ink jet printing of etchant or modifier materials for creating patterns, particularly for electronics and display applications. The present invention also relates to devices made using the processes.
Claims22
A process comprising the steps of:
- providing a substrate having a surface layer thereon wherein said surface layer comprises a substrate-side and a surface-side;
- providing a deposit composition comprising from 1 to 50 percent by weight of an etchant or modifier in a dispersing vehicle;
- jetting droplets of said deposit composition onto the surface-side of said surface layer in an image-wise manner;
- allowing the etchant or modifier in the composition to react with the surface layer on said substrate thus forming products of the etching reaction and thereby removing or otherwise modifying the physical properties of the surface layer in the desired image.

A method of forming an RFID device comprising the steps of:
- providing a substrate having a surface layer thereon wherein said surface layer comprises a substrate-side and a surface-side;
- providing a deposit composition comprising from 1 to 50 percent by weight of an etchant or modifier in a dispersing vehicle;
- jetting droplets of said deposit composition onto the surface-side of said surface in an image-wise manner;
- allowing the etchant or modifier in the composition to react with the surface layer on said substrate thus forming products of the etching reaction and thereby removing or otherwise modifying the physical properties of the surface layer in the desired image.
