    摘要： Nanoscale particles of benzimidazolone pigments are made by providing one or more organic pigment precursor(s) to a benzimidazolone pigment, providing a solution or suspension of a sterically bulky stabilizer compound that associates non-covalently with a benzimidazolone moiety on one of the pigment precursors, wherein the sterically bulky stabilizer compound is selected from the group consisting of substituted pyridine derivatives, alkylated benzimidazolone compounds, alkylated derivatives of aromatic acids, and mixtures thereof, and carrying out a coupling reaction to form a benzimidazolone pigment composition, whereby one or more functional moieties on the benzimidazolone pigment is non-covalently associated with the sterically bulky stabilizer, so as to limit an extent of particle growth and aggregation and results in nanoscale pigment particles.

    摘要： The present invention relates to surface-treated pigments of formula (I), wherein Ar?1 and Ar2¿ are each independently of the other a phenyl or naphthalene group, n1 and n2 denote a value from 0 to 0.15, the sum of n1 and n2 being a value from 0.01 to 0.15, n is an integer 1 or 2, X1 is a branched or unbranched alkyl radical or alkenyl radical having from 1 to 25 carbon atoms, it being possible for the alkyl radical to be interrupted by one or more S or O atoms, and is preferably a group -Y-(CH¿2)m-R?1, wherein Y is a group -CH¿2?-, -O-, -S-, -C(O)O-, -C(O)-, -C(O)-NH-, -SO2NH- or -SO2- and R?1¿ is a hydrogen atom or a group -NR2R3, wherein R?2 and R3¿ are each independently of the other a hydrogen atom or a C¿1-6? alkyl radical, and m is an integer from 1 to 24, especially from 12 to 18, X?2¿ is a group -COOH, -SO¿3?H or -P(O)OX?3OX4¿, wherein X?3 and X4¿ are each independently of the other a hydrogen atom or a C¿1-6? alkyl radical, especially a hydrogen atom, and pigment denotes an organic pigment or a mixture of organic pigments, including solid solutions and crystalline solid solutions. Compared with untreated pigments, the surface-treated pigments exhibit better rheological properties and/or no warping in the pigmenting of partially crystalline plastics.

    摘要： The present invention generally relates to colloidal systems, which may include colloidal particles and/or other types of particles. One aspect of the invention is generally directed to a system comprising fluidic droplets that can be at least partially solidified, e.g., to form colloidal particles. In some embodiments, particles comprising an at least partially solid outer phase encapsulating an inner phase are formed. The inner phase may be any phase, e.g., a solid, a liquid, or a gas. In some cases, solidifying at least a portion of the outer phase of the droplets to form particles may increase the stability of the particles and/or the colloidal system containing the particles. In one set of embodiments, melting or liquefying the outer phase of the particles (for example, by heating the particle to a temperature above a threshold temperature) can allow release of an agent contained within the inner phase, and/or allow the inner phase to coalesce with a phase external to the particles. The melting temperature of the outer phase can be controlled in some embodiments such that the outer phase will melt above a predetermined temperature. In some embodiments, the particles may be formed to be essentially free of an auxiliary stabilizing agent. In some embodiments, an agent may be encapsulated within a particle with relatively high efficiency. Other aspects of the invention are generally directed to methods of making and using such colloidal systems, e.g., containing such particles, kits involving such colloidal systems, or the like.
