Abstract

The invention pertains to a composition comprising silver metal particles and an additive, characterized in that the additive is a metal salt or a mixture of metal salts wherein the metal is yttrium or a metal of group 2 of the Periodic System, and wherein the composition comprises <2 atom % of the metal. Preferably, the salt is a salt of magnesium acetate. The compositions can be used to make temperature-resistant electrically-conductive silver-containing layers, for instance for use in AMLCD.

Claims

exact text as granted — not AI-modified
1 . A composition comprising silver metal particles and an additive, characterized in that the additive is a metal salt or a mixture of metal salts wherein the metal is yttrium, cobalt or a metal of group 2 of the Periodic System, and wherein the composition comprises <2 atom % of the metal.  
     
     
         2 . The composition of  claim 1  wherein the metal is magnesium.  
     
     
         3 . The composition of  claim 2  wherein the metal salt is magnesium nitrate or a salt of magnesium and an organic base.  
     
     
         4 . The composition of  claim 3  wherein the metal salt is magnesium acetate.  
     
     
         5 . The composition of  claim 1  wherein the composition comprises <1 atom % of the metal.  
     
     
         6 . The composition of  claim 1  wherein the silver metal particles are a colloidal silver sol.  
     
     
         7 . An electrically-conductive layer comprising a silver composition-containing layer, the composition comprising silver and a metal salt or a mixture of metal salts wherein the metal is a metal of group 2 of the Periodic System, and wherein the composition comprises <2 atom % of the metal.  
     
     
         8 . An article comprising the electrically-conductive layer of  claim 7 .  
     
     
         9 . An active matrix liquid crystalline display comprising the electrically-conductive layer of  claim 7 .  
     
     
         10 . Use of the composition of  claim 1  in the manufacture of silver-containing layers.
