Abstract
Official abstract text for this publication.
The present invention relates to a conductive metal ink composition which is properly applied for roll-printing process to form conductive pattern with improved conductivity, and the method of preparing a conductive pattern using the same. The conductive metal ink composition comprises a conductive metal powder; an organic silver complex where an organic ligand including amine group and hydroxyl group binds with a silver (Ag) salt of aliphatic carboxylic acid; a non-aqueous solvent comprising a first non-aqueous solvent having a vapor pressure of 3 torr or lower at 25° C. and a second non-aqueous solvent having a vapor pressure of higher than 3 torr at 25° C.; and a coatability improving polymer.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for forming a conductive pattern, comprising the steps of: coating a conductive metal ink composition on a roller; forming a pattern of the ink composition corresponding to the conductive pattern on the roller, by contacting the roller with a cliché which has intaglio pattern corresponding to the conductive pattern; transferring the pattern of the ink composition on the roller onto a substrate; and sintering the transferred pattern on th…
