Abstract (en)

[origin: WO2022161737A1] The invention relates to a mask exposure method comprising the following steps: - the providing of a carrier substrate; - the print application of a radiation-crosslinkable washable dye layer to the full area of the carrier substrate; - the exposure of the radiation-crosslinkable washable dye layer in defined regions to radiation by means of a radiation mask, such that the washable dye is cured in the defined regions; - the applying of a metallization over the full area; - the removing of the non-radiation-exposed washable dye outside the defined regions together with the metal present thereon with the aid of a solvent, such that the resultant carrier substrate has cured washable dye with metal applied thereto only in defined regions.
