Antimony-doped tin oxide, infrared-ray-absorbable pigment, infrared-ray-absorbable ink, printed matter, and method for producing antimony-doped tin oxide

摘要

An antimony-doped tin oxide which comprises tin oxide and antimony oxide and fulfills the following requirement (a) and/or (b): (a) the half-width value (Δ2θ) around 2θ= 27˚as determined by an X-ray diffraction measurement is 0.35 or less; and/or (b) the content of antimony oxide is 0.5 to 10.0 wt% relative to the weight of the antimony-doped tin oxide and the crystallinity, which is a value determined by dividing a peak value of a peak appearing around 2θ= 27˚as determined by an X-ray diffraction measurement by the half-width value (Δ2θ), is 18092 or more.
