Abstract:
1. A process for removing a selected portion of a coating from a coated metal conductor comprising irradiating a selected portion of the coating of the coated metal conductor with laser irradiation in the range of medium to high energy thereby vaporizing the selected portion of the coating without leaving a residue of the coating on the metal conductor; wherein the coating comprises A) 1 wt. % to 90 wt. %, based on the total weight of the binder, of one or more binders, B) 0.3 wt. % to 25 wt. %, based on the total weight of the binder, of one or more reactive particles based on an element-oxygen bound network with elements selected from the group consisting of aluminum, tin, boron, germanium, gallium, lead, silicon, zinc, the transition metals, the lanthanides, and actinides, and C) 0 wt. % to 95 wt. %, based on the total weight of the binder, of one or more conventional additives, solvents, pigments, and/or fillers, wherein the total of A)+B)+C) equal 100% and wherein the reactive particles of component B are based on the element-oxygen network, on the surface of which reactive functions R R wherein R R R R
