Process of depositing a metallic pattern on a medium, said process comprising: generating pulsed laser beams from a pulsed laser source, wherein the laser beams have a wavelength for which the medium is substantially transparent, focussing the laser beams onto a target layer comprising inorganic particles, dispersed in a laser light degradable/combustible organic matrix, said target layer producing ejecta in response to an interaction of said laser beams and said target layer, accumulating at least a portion of said ejecta on said medium within the desired pattern, providing the pattern by electroless metal plating. The invention further relates to a transparent medium comprising a metallic pattern wherein the adhesion between the metallic pattern and the medium is at least 5N/cm.
