    Abstract: Copper phthalocyanine (CuPc) was converted to a form suitable for colouring use by grinding the crude prod. until it consisted of agglomerates composed of particles whose mean size was 0.05 microns or less, suspending the ground material in the 0.8-10 fold (pref. 2-8 fold) amt. by wt. of an organic solvent (1), and heating to 20-180 deg.C (pref. 50-150 deg.C) until the desired colouring strength was attained. Crude CuPc-prepd. e.g. by fusing a mixt. of o-phthalodinitrile and CuCl in anhyd. Na2SO4, and freed from salt by H2O treatment prior to grinding (10-40 hours in a ball mill, pref. 25-35 hours) - has a chlorine content of 2-4 wt.%. (1) may be amino-2-8C-alkanols (pref. 3-aminopropanol), mono- or bi-nuclear 6-membered aromatic nitrogen heterocycles (pref. pyridine), N,N-di(1-8C alkyl) amides of 1-3C carboxylic acids, N-methyl(or cyclohexyl)pyrrolid-2-one, or mixts. of these solvents. Depending on the organic solvent used, the pigment form was isolated from the mixt. either by direct filtration at 80-120 deg.C (or after treatment with H2O or aq. mineral acid) or by first removing the solvent by steam distn. and then filtering the resulting aq. suspension. The CuPc pigment forms have excellent dispersibility and high colouring strength.

    Abstract: Phthalocyanine formulations which comprise a mixture of (a) phthalocyanine and (b) from 2 to 20% by weight, based on (a) of one or more urea derivatives of the formula K-(-NHCO-NH-R)2 (I), where K is 1,5-naphthylene or 4,4'-diphenylenemethane, R is alkyl of 12 to 18 carbon atoms, alkenyl of 12 to 18 carbon atoms, 3-(alkoxy of 8 to 18 carbon atoms)-propyl, 2-(alkylamino of 8 to 18 carbon atoms)-ethyl or (CH2)3-O-(CH2-CH2O)n-R1, R1 is alkyl of 2 to 8 carbon atoms or phenyl and n is 1, 2, 3 or 4, and which are obtained by milling (a) with (b) in the absence of a grinding medium. When used in printing inks, such as offset printing inks, the formulations give deeply colored prints in very pure hues, with very low graininess of the ink.

    Abstract: Phthalocyanine compsns. which are stable with respect to recrystallisation and modification, giving colourations of high brilliances, comprises (a) a phthalocyanine pigment and (b) 2-40 wt. % on (a) a salt or a homogeneous mixt. contg. (i) one or more phthalocyanine derivs. of formula Pc -X-NR1R2 n in which Pc is a metal free n-valent phthalocyanine residue, a cuprophthalocyanine or a mixt. of these, X = -CH2-, -SO2-N-(R)-alk-, -CH2-CH2-COOC2H4- or -CH2-CH2-COO-C3H6-, R1 = H, 1120C alkyl, phenyl gp. opt. substd. by methyl (m)ethoxy or Cl, -(C2H4-NH)zH or -(C3H6-NH)zH, or -(C3H6-NH)zH, R2 = H, 1-6C alkyl or 6-8C cycloalkyl gp. alk = linear or branched satd. alkylene gp. with 2-6C, R = H or 1-4C alkyl, R and R2 may be bound together, n = 2-5, z = 1-3 and the gp. NR1R2 represents a satd. heterocyclic gp. with 5, 6 or 7 members opt. contg. O, N or S as other members of the ring, and (ii) a 1-20C aliphatic sulphonic acid, an aromatic sulphonic acid carrying one or two 1-20C alkyl gps. and opt. a OH gp. as substituents, or mixts. of these the ratio of (i):(ii) being 1:1 to 1:5 moles, as stabiliser, and opt. (c) one or more org. liqs. or solns. of resins in org. liqs. Prods. are useful pigmenting agents for printing inks, paints, plastics such as PVC, polyethylene etc. and remain stable in use so that they do not crystallise out on storage or change tint due to modification of the crystal form.

    Abstract: A pigment formulation which comprises (a) a finely divided organic pigment and (b) one or more urea derivatives of the formula K-(NH-CO-NH-R)2, where R is C12-C18-alkyl, C12-C18-alkenyl, C8-C18-alkoxypropyl or -(CH2)3-O-(C2H4O)n-R1, R1 is C2-C8-alkyl or phenyl, n is 1, 2, 3 or 4 and K is 1,5-naphthylene or 4,4'-diphenylenemethane, with or without (c) up to 5% by weight, based on (a and b), of agents conventionally present in pigment formulations. In binder solutions, the pigment formulations give printing inks and paints possessing excellent tinctorial properties. Some of the compounds (b) prevent the conversion of alpha -copper phthalocyanine to the beta -modification.

    Abstract: A phthalocyanine formulation which is stabilized against recrystallization and change of modification and which contains, as the stabilizer (a) a finely divided phthalocyanine as the pigment and (b) a salt or the corresponding homogeneous mixture of ( alpha ) a phthalocyanine derivative, which carries basic groups (R1 = H, alkyl of 1 to 20 carbon atoms, unsubstituted or substituted phenyl, -C2H4-NH)zH or -(C3H6-NH)zH, z = 1, 2 or 3, and R2 = H, alkyl of 1 to 6 carbon atoms or cycloalkyl of 6 to 8 carbon atoms) and ( beta ) an aliphatic sulfonic acid of 8 to 20 carbon atoms, a monoalkylbenzenesulfonic acid or dialkylbenzenesulfonic acid where alkyl is of 6 to 20 carbon atoms, or a monoalkylnaphthalenesulfonic acid or dialkylnaphthalenesulfonic acid where alkyl is of 6 to 20 carbon atoms, which acids may be substituted by hydroxyl, the molar ratio of alpha : beta being from 1:1 to 1:5, and, if desired, one or more organic fluids or solutions of resins in these fluids. The formulations are stable even in aromatic hydrocarbons and produce pure, deep colorations which have high gloss.
