Abstract (en)
[origin: EP2284019A1] A security paper for laser engraving comprises a paper substrate layer (110) comprising an antimony-doped tin oxide laser-marking pigment and titanium white, the paper substrate layer (110) being coated with a coating layer (120) comprising the antimony-doped tin oxide laser-marking pigment, such that when the security paper (100) is subject to a laser beam, the antimony-doped tin oxide laser-marking pigment causes change of color of the security paper (100) both within the paper substrate layer (110) and the coating layer (120).
