    Abstract: Composite sheets include at least two adjacent fibrous monolayers of unidirectionally aligned high tenacity polyethylene fibers, whereby the direction of orientation between the polyethylene fibers of said two fibrous layers differs by at least 80° and up to 90°, the fibers having a tenacity of at least 1.5 N/tex, the fibers being in a matrix comprising a homopolymer or copolymer of ethylene and wherein the homopolymer or copolymer of ethylene has a density as measured according to ISO1183 of between 870 to 980 kg/m3. The composite sheets have an areal density of between 50 and 500 g/m2, wherein the composite sheets have an areal density normalized in-plane shear force measured at 25° C. evaluated according to a bias extension test method variant of ASTM D3518 of at least 0.40 N·m2·g−1 and lower than 5.0 N·m2·g−1 at 10 mm clamp displacement and an areal density normalized in-plane shear force measured at 110° C. and clamp displacement of 10 mm of at least 0.01 N·m2·g−1 and lower than 0.20 N·m2·g−1.

    Abstract: 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.
