    摘要: A sheet material suitable for imaging by laser radiation includes a substrate, an adhesive layer comprising a thermoplastic or elastomeric polymer coated onto the substrate, and a particle layer adhered to the adhesive layer and comprising a plurality of carbon or metal or mineral particles that are subject to laser ablation. The particle layer preferably contains alumina particles. The adhesive layer may be filled with particles and is preferably filled with titanium dioxide particles that are more sensitive to laser radiation than the thermoplastic or elastomeric polymer. Preferably, a silicone or silicate layer that is not subject to laser ablation overlies the particle layer.
