Disclosed herein is a colored photosensitive resin composition including a copolymer, an epoxy resin compound or a compound derived therefrom, a polymerizable compound, a photoinitiator, and a colorant, wherein the photoinitiator includes an oxime compound and a triazine compound. The composition, when formed into a cured film, may facilitate the fabrication of necessary height difference and satisfy the requirements of sensitivity and an exposure margin for light shielding spacers, and, thus, is useful as a material for manufacturing a light shielding spacer such as a black column spacer used in various electronic parts including the panels of an LCD and an OLED display.
The present invention relates to a method of preparing a yellow pigment comprising an asymmetric quinolonoquinolone in an amount greater than 5% by weight of the yellow pigment. Also disclosed are modified yellow pigments comprising this yellow pigment having attached at least one organic group as well as inkjet ink compositions comprising the yellow pigments or the modified yellow pigments.
An object of the present invention is to provide a novel squarylium dye that can achieve an equivalent chromaticity value of even a colored resin composition having a low content of the squarylium dye as compared with a colored resin composition comprising a conventional squarylium dye. The present invention provides a compound represented by the formula (I) wherein R
