Abstract (en)
[origin: EP1529637A1] The invention relates to a laser-engravable element for use in a flexographic printing plate or a hand or coding stamp comprising a thermoset crosslinked copolymer obtainable from polyether urethane (meth)acrylate pre-polymer and (meth)acrylic monomer, oligomer and/or polymer. Such element is preferably used for making hand or coding stamps. The invention further pertains to a method of laser engraving comprising engraving a pattern into the surface of the element, the pattern being formed by decomposing and/or evaporating part of the copolymer of the element by means of irradiating with a laser beam, optionally followed by a wash step to remove remains of decomposed copolymer.
