摘要:
Mixed pigments containing an organic pigment component and an inorganic pigment component imparting improved gloss and other desirable properties to organic coatings containing the same in relatively large amounts are prepared by synthesizing the organic component in the presence of the inorganic component in a liquid medium inert to the inorganic component, such as nickel titanium yellow or chromium titanium yellow.
摘要:
A compound of the formula ##STR1## wherein Y represents an arylene group optionally substituted by a halogen atom, an arylsulfonyl group or an acyl group, Z represents a 1,2-naphthylene, 2,3-naphthylene, 1,8-naphthylene or 2, 2'-biphenylene group optionally substituted by a halogen atom, and either one or both of the rings A and B optionally contain a substituent. This compound can be obtained by reacting a quinoline derivative with an aryldicarboxylic acid or its reactive derivative, and if desired, halogenating the resulting product. A yellow organic pigment comprising this compound as a coloring ingredient is useful for coloring polymeric materials.

3-HYDROXY-QUINOPHTHALONE DYESTUFFS SUBSTITUTED IN THE 4-POSITION BY AN ETHER OR THIOETHER GROUP, AND A PROCESS FOR PREPARING THEM. SAID DYESTUFFS YIELD ON SYNTHETIC FIBROUS MATERIALS, ESPICIALLY THOSE FROM POLYEHYLENE TEREPHTHALATES, YELLOW DYEINGS HAVING GOOD FASTNESS TO LIGHT, WET PROCESSING AND SOLVENTS AND A REMARKABLY GOOD FASTNESS TO THERMOFIXATION AND IRONING.
摘要:
The invention comprises basic dyes of formula wherein R1 is hydrogen or a C1-C8 alkyl group, R2 is a methyl or ethyl group, R3 is a chlorine or bromine atom, or cyano or C1-C8 alkyl-sulphonyl group, R4 is a hydrogen, chlorine or bromine atom and Z is a C1-C3 alkylene or -CHOH.CH2-group. The dyes are prepared by diazotizing an amine of formula and coupling the diazonium compound with a compound of formula The dyes are preferably used to colour articles made from polymers composed of more than 80% acrylonitrile in red, blue or brown shades.
