发明名称	Preferentially etching metal coatings on plastic or paper foil - using pulsed laser beam operating in ultraviolet range
摘要	<p>Etching figures and lines in a coating made of a vaporisable material e.g. Al consists of exposing the coating to a pulsed laser beam operating in the UV spectral range. The wavelength of the beam is chosen so that the energy of the beam is completely absorbed by the coating and exceeds the threshold energy density for vaporisation. USE/ADVANTAGE - Structuring the metal coating on foil made of polymer of paper. This coating is preferentially removed without heating and thereby harming the surrounding areas.</p>
