摘要:
The invention relates to disazo pigments of the formula ##STR1## wherein R is an ethyl, propyl or isopropyl radical. These pigments colour plastics, especially rigid PVC, in brown shades of excellent fastness properties.
摘要:
Disazo pigments of the formula ##STR1## WHEREIN X and Y denote hydrogen or halogen atoms, alkyl or alkoxy groups containing 1-6 carbon atoms, or aryloxy, trifluoromethyl, nitro, cyano or carboxylic acid ester groups, or wherein X and Y conjointly denote a fused benzene ring are useful for coloring plastics, lacquers and printing inks in yellow shades.
摘要:
The instant invention relates to monoazo pigments containing a hydroxynaphthoylaminobenzimidazolone radical of the following formula ##STR1## These pigments are useful for coloring high molecular weight materials in orange to brown shades of especially good fastness properties.
摘要:
Diazo pigments of the formula ##STR1## wherein R denotes an alkyl, cycloalkyl, aralkyl, aryl or heterocyclic radical, X denotes a hydrogen or halogen atom, an alkyl or alkoxy group containing 1 to 4 carbon atoms, or a nitro, cyano, trifluoromethyl or carboxylic acid ester group, and Y denotes a hydrogen or halogen atom, an alkyl or alkoxy group containing 1 to 4 carbon atoms or a nitro, cyano, trifluoromethyl or carboxylic acid ester group, are useful for coloring plastics and printing inks in fast yellow to orange shades.
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:
The present invention concerns the disazo pigment of the formula ##STR1## The new pigment is useful for coloring plastic material in pure red shades of high tinctorial strength and outstanding fastness to light and migration.
