Claims

1. AN ELECTRICALLY CONDUCTIVE TRANSPARENT ARTICLE COMPRISING:

A BODY OF TRANSPARENT GLASSY SILICEOUS MATERIAL HAVING A SMOOTH CONTINUOUS SURFACE;

A CONTINUOUS INTERMEDIATE TRANSPARENT ADHESIVE LAYER DEPOSITED BY MOLECULAR DEPOSITION ON SAID SMOOTH CONTINUOUS SURFACE, SAID LAYER COMPRISING A METALLIC OXIDE CHARACTERIZED BY STRONG MOLECULAR ADHESION BOTH TO GLASSY SILICEOUS MATERIAL AND TO METALS, THE ADJACENT SURFACES OF SAID BODY AND LAYER BEING IN CONTINUOUS DIRECT SURFACE TO SURFACE CONTACT AND DEFINING A SMOOTH CONTINUOUS INTERFACE;

AND A CONTINUOUS FILM OF A METAL SELECTED FROM THE GROUP CONSISTING OF GOLD, SILVER, COPPER, IRON AND NICKEL DEPOSITED BY MOLECULAR DEPOSITION ON SAID ADHESIVE LAYER AND PERMANENTLY AND DIRECTLY ADHERED THROUGHOUT ITS AREA TO SAID ADHESIVE LAYER BY MOLECULAR FORCES, SAID FILM BEING SUBSTANTIALLY UNIFORM IN THICKNESS, THE THICKNESS OF SAID FILM BEING SUCH THAT IT HAS AN ELECTRICAL RESISTIVITY OF NOT MORE THAN 150 OHMS PER SQUARE AREA AND THE LIGHT TRANSMISSION OF THE ARTICLE IS AT LEAST 50%, THE OUTER SURFACE OF SAID METAL FILM BEING SUBSTANTIALLY SMOOTH.

15. AN ARTICLE AS DEFINED IN CLAIM 1 IN WHICH THE ARTICLE IS A PANE OF GLASS WHICH IS LAMINATED TO A SECOND PANE OF GLASS WITH AN INTERMEDIATE PLY OF PLASTIC IN CONTACT WITH THE COATED SIDE OF THE FIRST PANE.
