Abstract: WHEREIN R1 and R2 are identical or different and represent a hydrogen or halogen atom, an alkyl or alkoxy group having each 1 to 4 carbon atoms, an aryloxy, aryl, carbonamide or N-alkyl carbonamide group or which represent together the radical of an aromatic or heterocyclic ring, and 0.5 to 15 percent by weight of one or several linear trans-quinacridones of the general formula
WHEREIN Y represents a straight-chained or branched alkyl or alkoxy radical having 6 to 18 carbon atoms, m and n are integers of from 0 to 1 and the sum of n and m being 1 or 2 and R1 and R2 having the meanings given above. These mixtures are obtained by mixing with one another starting compound or final products substituted accordingly during the process of preparation or formation and processing in the manner usual for quinacridones. As compared to the single components the mixture thereof is more transparent and has a better color intensity, a better dispersability and fluidity of the lacquers colored with them and frequently more brilliant shades.
Quinacridone mixtures consisting of 85 to 99.5 percent by weight of one or several linear trans-quinacridones of the general formulaAbstract translation: 由85至99.5重量％的一种或几种通式为WHERE R1和R2的直链反式喹吖啶酮组成的喹吖啶酮混合物是相同或不同的，代表氢或卤素原子，具有1至4个碳原子的烷基或烷氧基 ，芳氧基，芳基，碳酰胺或N-烷基碳酰胺基，或者一起表示芳族或杂环基团，以及0.5至15％（重量）的一种或几种通式的线性反式 - 喹吖啶酮，其中Y代表直链 具有6至18个碳原子的链或支链烷基或烷氧基，m和n是0至1的整数，n和m的和为1或2，R1和R2具有上述含义。 这些混合物通过在制备过程中相应地起始化合物或最终产物与通常用于喹吖啶酮的方式相互混合而获得。 与单一成分相比，其混合物更透明并且具有更好的颜色强度，与它们着色的漆的更好的分散性和流动性以及通常更加辉煌的色调。

Abstract: A PROCESS FOR THE WET GRINDING OF PIGMENTS WHICH COMPRISES EFFECTING THE GRINDING IN AN AQUEOUS MEDIUM CONTAINING 0.1-20 PERCENT OF A BASE SELECTED FROM THE GROUP OF WATER SOLUBLE ALKALI METAL-, ALKALI EARTH METAL- OR AMMONIUM COMPOUNDS. THE ADDITION OF BASES INPROVES THE TRANSMISSION OF GRINDING ENERGY TO THE MATERIAL BEING GROUND AND RESULTS IN THE PRODUCTION OF PURER PIGMENTS OF BETTER TINCTORIAL STRENGTH IN A RELATIVELY SHORT GRINDING TIMEFURTHERMORE, THE GRINDING PROCESS ACCORDING TO THE INVENTION IS CARRIED OUT IN A SIMPLE AND INEXPENSIVE WAY.
