Title:
NEAR-INFRARED ABSORBING DYE, OPTICAL FILTER AND IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/230570
Kind Code:
A1
Abstract:
The present invention relates to: a near-infrared absorbing dye which is composed of a compound represented by formula (A1); and a near-infrared absorbing dye which is composed of a compound represented by formula (A2). In formula (A1) and formula (A2), each of R1, R2, R5 and R6 independently represents a hydrogen atom, a halogen atom, a hydroxyl group, or an optionally substituted alkyl group, alkoxy group, aryl group or alaryl group which may contain an unsaturated bond or an oxygen atom between carbon atoms; and each of R3, R4, R7 and R8 independently represents an optionally substituted linear or branched chain alkyl group which may contain an unsaturated bond, an oxygen atom, an alicyclic ring or an aromatic ring between carbon atoms.
