    • PURPOSE: A method for preparing a nanoscale pigment particle composition is provided to obtain pigment particles useful for paint, coating, ink jet printing, optoelectronic imaging components, optical color filters, photograph members, and cosmetics. CONSTITUTION: A process for preparing nanoscale particles of benzimidazolone pigments comprises: providing one or more organic pigment precursor 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 the pigment precursors are incorporated within the benzimidazolone pigment and 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 result in nanoscale-sized pigment particles.
    • 目的:提供一种制备纳米级颜料颗粒组合物的方法,以获得可用于涂料,涂料,喷墨印刷,光电成像组件,光学滤色器,照相构件和化妆品的颜料颗粒。 构成:制备苯并咪唑酮颜料的纳米尺寸颗粒的方法包括:向苯并咪唑酮颜料提供一种或多种有机颜料前体; 提供空间庞大的稳定剂化合物的溶液或悬浮液,其与一种颜料前体上的苯并咪唑酮部分非共价缔合,其中空间庞大的稳定剂化合物选自取代的吡啶衍生物,烷基化苯并咪唑酮化合物,烷基化衍生物 的芳族酸及其混合物; 并进行偶联反应以形成苯并咪唑酮颜料组合物,由此将颜料前体引入到苯并咪唑酮颜料中,并且苯并咪唑酮颜料上的一个或多个官能部分与空间庞大的稳定剂非共价相关,以限制其程度 的颗粒生长和聚集,并导致纳米级颜料颗粒。
