摘要:
A water swellable resin composition comprises a water swellable resin and a medium such as a plasticizer, solvent, resin or resin solution. The resin is an alkali metal salt and/or hydrophilic amine salt of a copolymer of hydrophobic polymer chains having an α,β-ethylenically-unsaturated group at end thereof and a monomer composed principally of (meth)acrylic acid.

A pixel-forming colorant composition contains at least one green colorant selected from the group consisting of the following pigments (A) and (B) and pigment derivative (C): (A) a copper phthalocyanine green pigment obtained by reacting at least one of a phthalic acid substituted on average with from 3.5 to 4.0 bromine atoms and a derivative thereof with a copper salt, substituted on average with from 14 to 16 bromine atoms, and substituted with no chlorine atom; (B) a copper phthalocyanine green pigment obtained by reacting a mixture, which comprises at least one of a phthalic acid having at least one bromine atom and a derivative thereof and at least one of a phthalic acid having at least one chlorine atom and a derivative thereof, with a copper salt, substituted on average with not less than 12 but less than 16 bromine atoms, and substituted on average with not more than 4 but more than 0 chlorine atom(s); and (C) a green pigment derivative obtained by introducing at least one substituent in at least one of the copper phthalocyanine green pigments (A) and (B). The pixel-forming colorant composition is useful for the formation of G pixels of three primary-color pixels on color filters.
摘要:
A pigment dispersant contains the following component (a) alone or the following components (a) and (b) in combination: Component (a): a composite pigment formed of a diketopyrrolopyrrole pigment having a sulfonic group and another diketopyrrolopyrrole pigment having no sulfonic group, wherein the number of sulfonic group per molecule of the diketopyrrolopyrrole pigments in the composite pigment is from 0.05 to 0.5; and Component (b): a pigment other than the component (a), wherein the pigment has a sulfonic group or its metal salt, ammonium salt or amine salt. Also disclosed are a colored composition for color filters, a process for the fabrication of a color filter, the color filter fabricated by the process, an image display device including the color filter, and an information communication equipment including the image display device. These colored composition, process, color filter, image display device and information communication equipment all make either direct or indirect use of the pigment dispersant.
摘要:
Pigment dispersions for color filters are composed of pigments, dispersants, film-forming resins and liquid media. The dispersants comprises compounds represented by the following formula (I): wherein X and X' each independently represent H, OH, alkoxy, primary, secondary or tertiary amino, or acylamino; Y represents an anthraquinonylamino, phenylamino or phenoxy group having H, OH, alkoxy, primary, secondary or tertiary amino, or acylamino at the 4-position or 5-position; A and B each independently represent alkyl, cycloalkyl or aryl, and at least one of A and B has at least one substituent group containing a basic nitrogen atom; and Z represents H, CN, halogen, alkyl, alkoxy, NO 2 , benzoylamino or 3-benzoyl, and the 3-benzoyl group may be fused together with X to form an acridone ring. These pigment dispersions are useful for the production of color filters.

摘要:
Disclosed is a pigment dispersant represented by the following formula (1): wherein X represents a hydrogen atom or an acylamino group; Y represents a specific aromatic group; Z represents a specific aromatic group or a C 2-30 aliphatic, alicyclic or heteroalicyclic amine reaction residual group having at least one amino group; G represents a reaction residual group of at least one compound selected from C 2-30 aliphatic, alicyclic and heteroalicyclic hydrocarbons each of which has at least one amino group; n is an integer of from 0 to 3; and when N stands for 0, Z represents a reaction residual group of a C 2-30 aliphatic, alicyclic or heteroalicyclic polyamine having at least two amino groups. A pigment dispersion making use of the dispersant and a color filter produced from the pigment dispersion are also disclosed.
