摘要:
An azo pigment showing excellent coloring characteristics such as tinctorial strength and hue and excellent fastness such as light fastness, and a pigment dispersion containing the azo pigment are provided.An azo pigment represented by the following general formula (1) and a pigment dispersion containing the pigment: wherein G represents a hydrogen atom, an aliphatic group, an aryl group, a heterocyclic group, an acyl group, an aliphatic oxycarbonyl group, a carbamoyl group, or a sulfonyl group, R1 represents an amino group, an aliphatic oxy group, an aliphatic group, an aryl group, or a heterocyclic group, R2 represents a substituent, A represents an aromatic 5- to 6-membered heterocyclic group, m represents an integer of from 0 to 5, and n represents an integer of from 1 to 4.
摘要:
There is disclosed a pigment dispersant comprises the compound represented by the following formula (I) or a metal salt, ammonium salt, amine salt or alkylammoniumchloride salt thereof.Also disclosed are a colored composition for CF, a process for the fabrication of a CF, 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:
Disazo pigments of the formula ##STR1## wherein R represents alkyl containing 1 to 6 carbon atoms, cyclohexyl or phenyl, and X and Y represent hydrogen, halogen, alkyl or alkoxy groups containing 1 to 4 carbon atoms which are useful for pigmenting high molecular organic material.
摘要:
Disclosed are pigments of the formula I, ##STR1## in which the X's, R.sub.1 and R.sub.2, independently, signify a fluorine, chlorine or bromine atom. They are useful, for example, for the pigmentation of synthetic polymers in the mass, in emulsion paints, printing inks and viscose and cellulose acetate spinning solutions and for dyeing paper in the stock.
摘要:
Disazo pigments of the formula ##STR1## wherein R.sub.1 is 2-nitro-5-chlorophenyl or 1-nitronaphthyl-2, R.sub.2 is naphthalene in which the azo, hydroxyl and --CO--group are in the 1,2,3-position and R.sub.4 is a phenylene or naphthalene group are prepared. The disazo pigments may be used for pigmenting high molecular organic materials such as cellulose ethers, polyamides, polyurethanes and acrylic. The pigments have very good fastness to migration, heat and to light.
IN WHICH R1 REPRESENTS A BENZENE RADICAL, R2 REPRESENTS A NAPHTHALENE RADICAL IN WHICH THE AZO, HYDROXY AND-CO GROUPS ARE IN 1,2,3-POSITION, R3 REPRESENTS A PARA-PHENYLENE OR DIPHENYLENE RADICAL, ARE VALUABLE PIGMENTS WHICH ARE USEFUL FOR COLORING PLASTICS AND LACQUERS IN ORANGE TO RED SHADES OF EXCELLENT FASTNESS.
摘要:
Compounds of the formula R1-N N-R2-CONH-R3 in which R1 and R3 each represents an aryl or a heterocyclic residue, at least one of the residues R1 and R3 being a phenomorpholone-(3) residue, and R2 represents a hydroxynaphthalene residue in which the azo, hydroxy and carboxylic acid amide groups are in 1,2,3-position or the residue of an enolizable or enolized ketomethylene compound are valuable pigments which are useful for coloring plastics and lacquers in fast yellow-to-red shades of excellent fastness properties.
