Method of Forming Mirrors on a Conducting Substrate

Abstract

The invention provides a method of producing a mirror under a layer of hydrophilic colloid ( 8 ) onto a transparent conducting layer ( 4 ) by coating the layer of hydrophilic colloid ( 8 ) onto the conductive substrate ( 4 ), placing the coated substrate in a plating solution ( 100 ), and passing current through the solution ( 100 ).

1 . A method of forming at least one metal layer on a conductive substrate comprising;
 coating a layer of hydrophilic colloid onto the conductive substrate,   placing the coated substrate in a plating solution, and passing current through the solution, thereby forming the metal layer underneath the layer of hydrophilic colloid.   
   
   
       2 . A method as claimed in  claim 1  wherein the conductive layer lies on a flexible support. 
   
   
       3 . A method as claimed in  claim 1  wherein the conductive substrate is patterned, all parts of the pattern being at least temporarily connected. 
   
   
       4 . A method as claimed in  claim 1 , wherein the conductive substrate is formed of a transparent material. 
   
   
       5 . A method as claimed in  claim 1 , wherein the conductive substrate is formed of indium tin oxide. 
   
   
       6 . A method as claimed in  claim 1 , wherein the coated substrate is placed in a silver plating solution.
