Document Type and Number:
WIPO Patent Application WO/2010/073633
Kind Code:
A1
Abstract:
Provided is an infrared ray-reflecting black pigment having an average particle size of 0.02 to 5.0 µm that is obtained by coating the surface of core particles formed from cupric oxide using a surface treatment agent such that the coating layer is acid-resistant and the amount of coating is 0.1 to 10 wt% with respect to the cupric oxide. Preferably the core particles formed from cupric oxide are core particles formed from a mixture and/or composite of the cupric oxide and a second component consisting of one or more pigments selected from the group comprising extender pigment, white pigment, and iron oxide having a sunlight reflectivity of 10% or greater, wherein the molar ratio of cupric oxide and the second component pigment which make up the core particles formed from cupric oxide is 0.1:0.9 to 0.95:0.5. The infrared ray-reflecting black pigment is a black pigment that comprises cupric oxide but is free of toxic elements, and has not only excellent infrared ray reflectivity, but also excellent acid resistance and paint stability.
