Title:
PHOTOSENSITIVE COLORING COMPOSITION FOR FORMING COLORED SPACER, CURED MATERIAL, COLORED SPACER, AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/138605
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a photosensitive coloring composition for forming a colored spacer, whereby the photosensitive coloring composition has high light-blocking properties and is capable of controlling a level difference between a main spacer and a sub-spacer, and of suppressing light leakage in the entire range of the visible wavelength region of 450 nm to 700 nm. This photosensitive coloring composition for forming a colored spacer contains a colorant (a), an alkali-soluble resin (b), a photopolymerization initiator (c), an ethylenically unsaturated compound (d), a solvent (e), and a dispersing agent (f), the colorant (a) including an organic pigment (a-1) and carbon black (a-2), the content ratio of the carbon black (a-2) with respect to the colorant (a) being 20% by mass or less, and the highest transmittance of the photosensitive coloring composition at a wavelength of 300 to 370 nm being 0.010% or higher.
