Title:
PIGMENT AND COLORED PHOTOSENSITIVE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2012/039286
Kind Code:
A1
Abstract:
The present invention provides a pigment with excellent solubility and heat resistance, and a new compound suitable for the pigment, in particular a yellow pigment having a wavelength of maximum absorption in the range of 400-450 nm. The present invention also provides a colored (alkaline developable) photosensitive composition using the above pigment and an optical filter using the above colored (alkaline developable) photosensitive composition, particularly, a color filter which does not reduce luminance, is suitable for image display devices such as liquid-crystal display panels, and, specifically, uses a compound represented by general formula (1) as a pigment. The content of the general formula (1) is as described in the specification.
