  • Patent number: 8553180
    Abstract: The present invention is to provide an ink-jet ink composition for a color filter, which shows excellent straightness and sustainability when ejected from a head, which is able to decrease the heaped amount of the ink and to prevent the ink from overflowing from the ink layer-forming portion, and which is able to form a cured layer with an excellent shape and excellent film properties when deposited onto a substrate by the ink-jet method. The present invention is also to provide a color filter using the same, a method for producing a color filter, and a liquid crystal display device. The ink-jet ink composition for a color filter of the present invention comprises: (A) a pigment comprising C.I. pigment blue 15:6 and C.I. pigment violet 23, (B) a pigment dispersing agent comprising a polyallylamine derivative, (C) a thermosetting binder and (D) an organic solvent, wherein the content of C.I. pigment violet 23 is 8 to 30% by weight of the pigment (A).

  • Publication number: 20130196059
    Abstract: A method for producing a color filter, by which a highly flat coloring layer can be efficiently formed even in the case of using an inkjet method, comprising steps of: an inkjet step of applying a coloring layer-forming coating liquid by an inkjet method at an opening of a black matrix substrate which includes a transparent substrate and a light shielding part that is formed on the transparent substrate and has the opening, and thereby forming a pre-drying coloring layer; a reduced-pressure drying treatment step of subjecting the pre-drying coloring layer to a reduced-pressure drying treatment, and forming a color filter substrate having a post-drying coloring layer formed thereon; and a baking treatment step of subjecting the color filter substrate to a prebaking treatment and subsequently to a post-baking treatment, and obtaining a color filter having a coloring layer formed thereon, wherein in the reduced-pressure drying treatment, the pre-drying coloring layer is subjected to the reduced-pressure drying t

  • Patent number: 7968622
    Abstract: An ink-jet composition for a color filter excellent in storage stability, straightness and sustainability at the time of ejection from a head, wherein a cured layer thereof is excellent in heat resistance, adhesive property, and solvent resistance. The ink-jet ink composition for a color filter is a specific epoxy group-containing polymer (A), a specific epoxy group-containing compound (B) having two or more specific epoxy groups and a polycarboxlic acid derivative (C) in which specific carboxylic acid (c1) having alicyclic hydrocarbon is rendered latent by vinyl ether (c2), wherein the equivalence ratio of carboxyl groups rendered latent by the polycarbonoxylic acid derivative (C) to the total epoxy groups contained in the epoxy-group containing polymer (A) and the epoxy-group containing compound (B) is in the range from 0.7 to 1.1.
