摘要:
The invention relates to a pigment composition of C.I. Pigment Blue 15:6, containing 0.5% to 15% by weight of an additive of the formula (1), based on the weight of the pigment, in which R1, R2, R3, R4, R5 and R6 independently of one another are hydrogen; C1-C22 alkyl or C2-C22 alkenyl, whose carbon chain in each case may be interrupted by one or more moieties —O—, —S—, NR9—, —CO— or —SO2— and/or may be substituted one or more times by hydroxyl, halogen, aryl, heteroaryl, C1-C4 alkoxy and/or acetyl; C3-C8 cycloalkyl, whose carbon framework may be interrupted by one or more moieties —O—, —S—, —NR10—, —CO— or —SO2— and/or may be substituted one or more times by hydroxyl, halogen, aryl, heteroaryl, C1-C4 alkoxy and/or acetyl; dehydroabietyl or aryl or heteroaryl, with R9 and R10 independently of one another being hydrogen or C1-C22 alkyl. The pigment composition of the invention is produced with application of a wet grinding process, more particularly a salt kneading operation.

A method for the finishing treatment of organic pigments includes allowing an, optionally milled, organic raw pigment and one or more ionic liquids to interact.
摘要:
The invention concerns a process for encapsulating pigment particles, which comprises (A) producing a dispersion of the pigment to be encapsulated, (B) then applying a polyelectrolyte layer to the surface of the pigment particles, (C) further applying a polyelectrolyte layer having opposite charge to (B), and/or adding low molecular weight, multivalent ions oppositely charged to (B), and (D) if appropriate repeating steps (B) and (C), said steps (B), (C) and if appropriate (D) being carried out in the presence of a nonionic surfactant.

摘要:
The invention relates to the dimeric compound of formula (II) wherein the two monomer-units are linked with each other either via R3 or via R4; the ring A is a five-or six-membered heteroaromatic ring, one of the groups R3 or R4 is an unsubstituted or substituted phenylene radical, the remaining group R3 or R4 is a C1-C4 alkyl, C5-C6 cycloalkyl, an unsubstituted or substituted phenyl, benzyl, benzanilide or naphthyl; or wherein the group NR4 together with the ring A constitutes a five-or six membered heterocycle that can be annelated with a benzene ring, and R3 is an unsubstituted or substituted phenylene radical. The inventive compounds can be used for pigmenting high-molecular organic materials.

The invention relates to novel fine-particle pigment preparations comprising fine-particle C.I. Pigment Blue 15:6 as a base pigment and pigment dispersants of formula (II) wherein CPC is a radical of a copper phthalocyanine, n is a number between 0.1 and 4, preferably between 0.2 and 2; m is number between 0.1 and 4, preferably 0.2 and 2; Kat is a cation from the group of alkali metals or H+; o is a number between 0 and 3.9, preferably between 0 and 1.8; and n=m+o; and R1, R2, R3, R4 independently represent hydrogen or a radical from the group comprising C1-C20 alkyl, C2-C20alkenyl, C5-C20cycloalkyl, C5-C20cycloalkenyl, C1-C4 alkylphenyl, the previously cited radicals being optionally branched and optionally substituted by sulf-, carboxy, hydroxy and halogen, with the proviso that one, two or three of the radicals R1 to R4 is/are hydrogen. The invention also relates to the method for producing said pigment preparations.
摘要:
The invention relates to a method for the pigmentation of a non-aqueous, organic coating material containing a solvent. The invention is characterised in that a coated, finely dispersed organic pigment with (meth)acrylate copolymers containing amino groups is incorporated into an organic coating material containing a solvent, said pigment having a discharge of energy which is reduced by at least 20% compared to the corresponding non-coated pigment.
