Abstract
Abstract The partial metallization of electrically conductive non-metallic patterns, for example transparent patterns of indium oxide and/or tin oxide or resistance layers of cermet material, on insulating carriers by means of an electroless plating solution. The plating is initiated by applying a potential difference for a short period of time between the patterns and an auxiliary electrode.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
55 words
A method of partially metallising electrically conductive non-metallic patterns on insulating substrates, characterized in that the part of the pattern to be metallised is immersed in an electroless plating solution and a potential difference is applied for a short period of time between the pattern and the solution so as to initiate the metal deposition.
Claim 2
Independent Claim
55 words
A method of partially metallising electrically conductive non-metallic patterns on insulating substrates, characterized in that the part of the pattern to be metallised is immersed in an electroless plating solution and a potential difference is applied for a short period of time between the pattern and the solution so as to initiate the metal deposition.
Claim 3
Dependent Claim
22 words
A method as claimed in claim 1 of partially metallising transparent patterns of indium oxide and/or tin oxide on a glass substrate.
Claim 4
Dependent Claim
39 words
A method as claimed in claim 1 of partially metallising resistance on conductor material consisting of metal oxide and/or finely divided metal in a vitreous matrix, or also of amorphous carbon particles or graphite particles dispersed in a binder.
Claim 5
Dependent Claim
17 words
A method as claimed in claim 1, in which said potential difference is applied for 10 seconds.
