Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
93 words
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.
Claim 2
Dependent Claim
93 words

Claim 3
Dependent Claim
94 words
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.
