Title:
NEAR-INFRARED ABSORBING FILTER
Document Type and Number:
Japanese Patent JP2006163376
Kind Code:
A
Abstract:
To provide a near-infrared absorbing dye which excels in light and heat resistances and ensures no change in its absorption wavelength even when mixed with another dye, and to provide a near-infrared absorbing filter containing the same, particularly a near-infrared absorbing filter for an electronic display.
The near-infrared absorbing filter has a layer containing a compound represented by formula (1) wherein R1 is a hydrocarbon group, carbonyl group, silyl group, H, cyano group or halogen; R2 is a hydrocarbon group, carbonyl group, hydrocarbon-thio group, silyl, H, cyano group or halogen, Y1 and Y2 are each a hydrocarbon group; and M1 is a metal.
