Title:
HIGHLY ELECTRICALLY INSULATING AZO-BASED BLACK PIGMENT, PRODUCTION METHOD, COLORED COMPOSITION, COLORING METHOD, AND COLORED ARTICLES
Document Type and Number:
WIPO Patent Application WO/2012/169506
Kind Code:
A1
Abstract:
The present invention provides a highly electrically insulating azo-based black pigment such that the pigment itself exhibits high electrical insulation properties, the azo-based black pigment can impart the optical characteristics of visible light shielding properties and infrared ray permeability by using same and has a molecular structure having in the molecule at least one azo group and at least one 2-hydroxy-11H-benzo[a]-carbazole-3-carboxylic acid amide residue introduced from a coupling component, the volume resistivity of the pigment itself is at least 1010 Ω·cm, and the average particle size thereof is 10-200 nm. The azo-based black pigment has a simple production method, exhibits superior physical properties and robustness in addition to the high electrical insulation properties of the pigment itself, can be applied to a variety of applications such as coatings for conductive wires and electrical circuits, including back sheets for solar generating modules and black matrices for color displays, and the use thereof is expected.
