A method for producing full-surface or partial metal films on a substrate includes placing a coating on a substrate. The coating is irradiated sheetwise with a laser to form the metal films. |

DETAILED DESCRIPTION We claim: 1. Method for producing full-surface or partial films on a substrate, which comprises preparing a solution from a group consisting of metal acetates, metal acetyl acetonates and metal formiates of a metal from which a metal film is to be made, and forming a coating on a substrate by applying the solution to the substrate and then irradiating the coating sheetwise to produce a full-surface or textured metal film by emitting radiation with excimer laser at seven discrete wavelengths in the UV range between 157 nm and 351 nm depending on the gas filling. 2. Method for producing full surface or partial films on a substrate, which comprises preparing a solution from a group consisting of metal acetates, metal acetyl acetonates and metal formiates of a metal from which a metal film is to be made, and forming a coating on a substrate by applying the solution to the substrate and irradiating the coating sheetwise to produce a full-surface or textured metal film with a dye laser pulsed by an excimer laser, the dye emitting radiation continuously in the UV range at wavelengths between 320 nm and 420 nm. 3. Method for producing full-surface or partial films on a substrate, which comprises preparing a solution from the group consisting of palladium acetates, and forming a coating on a substrate by applying the solution to the substrate and then irradiating the coating sheetwise to produce a full-surface or textured palladium film by emitting radiation with an excimer laser at seven discrete wavelengths in the UV range between 157 nm and 351 nm depending on the gas filling. 4. Method according to the claims 1, which comprises placing a prefabricated mask on the coating before irradiating the mask sheetwise with the laser to produce textured metal films. 5. Method according to the claims 2, which comprises placing a prefabricated mask on the coating before irradiating the mask sheetwise with the laser to produce textured metal films. 6. Method according to the claims 1, which comprises reproducing a beam of the laser on the coating with the aid of optical elements for irradiating the coating to produce textured metal films only at given locations at which textured films are to be produced
