Abstract
Official abstract text for this publication.
The present invention relates to an infrared reflecting blue pigment comprising a composite oxide comprising Co, Al and mg, wherein a content of Mg in the blue pigment is 11 to 22% in terms of a molar ratio thereof based on whole metal element present in the blue pigment, and the blue pigment has a BET specific surface area of 10 to 100 m 2 /g; and an infrared reflecting green pigment comprising a composite oxide comprising Co, Al, Mg and Fe, wherein a content of Mg in the green pigment is 11 to 22% in terms of a molar ratio thereof based on whole metal element present in the green pigment, a content of Fe in the green pigment is 0.5 to 20% in terms of a molar ratio thereof based on whole metal element present in the green pigment, and the green pigment has an average particle diameter of 0.02 to 1.2 μm.
First claim
Opening claim text (preview).
What is claimed is: 1. An infrared reflecting blue pigment comprising a composite oxide comprising Co, Al and Mg, wherein a total molar ratio of Co and Mg to total molar content of Al is 1:2, a content of Mg in the blue pigment is 11 to 22% in terms of a molar ratio thereof based on whole metal element present in the blue pigment, the blue pigment has a BET specific surface area of 10 to 100 m 2 /g, the infrared reflecting blue pigment has a solar radiation reflectance of 45 to 60%…
