摘要:
A colour laser markable laminate comprising: - a colour laser markable layer (11) comprising a leuco dye and an infrared absorbing compound; - an optional adhesive layer (12); - a polymeric support (13); and - an optional outerlayer (14); characterized in that the colour laser markable layer further comprises an acid scavenger and that the support, the optional adhesive layer or the optional outer layer comprises an UV absorbing compound.
摘要:
A backsheet (1) for a photovoltaic module (5) comprising a support (10) and a weather resistant outerlayer provided on a side of the support characterized in that the weather resistant outerlayer comprises an at least partially cured coating from a curable composition wherein the curable composition comprises a monofunctional methacrylate and a difunctional (meth)acrylate monomer.
摘要:
A laser markable material including a laser markable layer, present as a self-supporting layer or as a layer on a support, the laser markable layer comprising an infrared absorbing dye and a infrared absorbing pigment, characterized in that the amount of the infrared absorbing pigment is between 10 ppm and 1000 ppm relative to the total dry weight of the laser markable layer.
摘要:
Infrared dyes having an infrared absorption maximum above 1130 nm are disclosed which have minor colouration in the visual spectrum. The infrared dyes are especially useful for producing multicolour laser marked security documents having reduced background coloration and enhanced colour gamut.
