ABSTRACT:
A coating composition useful as an electrical insulation layer for metal conductors, particularly wires, that has improved de-coating properties for the partial de-coating of coated conductor by the use of laser irradiation; the coating composition comprisesA) 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 from the series of aluminum, tin, boron, germanium, gallium, lead, silicon, zinc, the transition metals and the lanthanides and actinides, andC) 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% andwherein the reactive particles of component B are based on the element-oxygen bound network, on the surface of which reactive functions R1and optionally, non-reactive and/or partially reactive functions R2and R3are bound by way of the oxygen of the network,R1being contained in an amount up to 98 wt. %, based on the weight of the particles, R2and R3in an amount from 0 wt. % to 97 wt. %, based on the weight of the particles, in the particle, in whichR1represents radicals of the metal acid; NCO, urethane, epoxide, epoxy, carboxylic acid anhydride, C═C double bond systems, OH, alcohols bound by way of oxygen, chelating agents, COOH, NH2, NHR4, and/or reactive resin components,R2represents radicals of aromatic compounds, aliphatic compounds, fatty acid derivatives; esters and/or ethers,R3represents resin radicals andR4represents radicals of acrylate, phenol, melamine, polyurethane, polyester, polyester imide, polysulfide, epoxide, polyamide, polyvinyl formal resins; aromatic compounds; aliphatic compounds; esters; ethers; alcoholates and/or chelating agents.
