<p><P>PROBLEM TO BE SOLVED: To provide an infrared absorptive pigment which has an improved brightness without deteriorating infrared absorptivity. <P>SOLUTION: A compound is obtained by calcining aluminum hydroxide, metastannic acid and antimony oxide. A mixing ratio of metastannic acid and antimony oxide is in the range of 80:20-98:2 in weight ratio, and aluminum hydroxide is 1-20% to the total amount of metastannic acid and antimony oxide. Preferably, metastannic acid:antimony oxide is 95:5-98:2, and aluminum hydroxide is 1.5% or more to the total amount of metastannic acid and antimony oxide. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
