Beschreibung
Zusammenfassung:	The present invention provides salts of a cation and an anion, wherein the cation comprises (i) a silsesquioxane moiety of formula (ii) a chromophoric moiety D, which may which may be substituted with one or more substituents selected from the group consisting of C1-10-alkyl, phenyl, halogen, OC1-6-alkyl, OH, NH2 and NO2, and (iii) a moiety of formula wherein L4 is C1-20-alkylene, phenylene-C1-20-alkylene or C1-20-alkylene-phenylene-C1-20alkylene, R11, R12, R13 and R14 are independently from each other hydrogen or C1-4-alkyl, R15, R16, R17 and R18 are independently from each other C1-4-alkyl, R19 is C1-20-alkyl, which may be substituted with phenyl, O-C1-6-alkyl or NO2, and d is an integer from 1 to 25, and electrophoretic devices comprising the salts.
