摘要:
Dispersions of organic pigments are produced by adding a surfactant to an aqueous slurry of an organic pigment followed by subjecting the slurry to ultrasonic radiation. The surfactant utilized is one or more of the surfactants selected from the group consisting of:1. the acidic salt of N-alkyl-N,N',N'-trimethyl-1,3-propanediamine,2. the acidic salt of N-alkyl-N,N',N'-tris(2-hydroxypropyl)-1,3-propanediamine,3. N-alkyl-N,N,N',N',N'-pentamethyl-1,3-propanediamine dichloride,4. the acidic salt of N-(N-alkyl-3-aminopropane)-N'-(3-aminopropane)-1,3-propanediaminewherein the alkyl group contains from about 12 to about 22 carbon atoms, and5. a poly(ethyleneoxide) ether of an 18 carbon alcohol having 9 units of ethylene oxide thereon.
摘要:
Diarylide yellow pigment compositions which are sulfonated with 2,2'disulfobenzidine and/or p-sulfo-acetoacetanilide are rendered hydrophobic by treatment with specific quaternary ammonium salts. The pigment compositions are easily flushed into flushed bases. When incorporated into printing inks, the pigments demonstrate improved color strength and transparency.
摘要:
In one embodiment, the present invention relates to a method of preparing a medium shade yellow pigment composition comprising making an azo pigment by coupling (i) two or more diazonium components made from two or more aromatic amines including 2-amino-5-chloro-4-ethylbenzene-1-sulfonic acid and 2-amino-4-chloro-5-methylbenzene-1-sulfonic acid with (ii) at least 1-(3′-sulfophenyl)-3-methyl-5-pyrazolone, and metallizing the azo pigment with a divalent metal to provide the medium shade yellow pigment composition. The medium shade yellow pigment composition is suitable for use in plastics, paints and inks.
