摘要： Pigment compositions comprising an organic pigment and a combination of at least two normally water-soluble coloured compounds (dyes) of opposing charge, i.e. of at least one anionic and one cationic dye are provided. The compositions impart improved rheology on non-aqueous pigment based printing inks and paints.

摘要： Azo compounds of formula (I), wherein X stands for halogen, in particular for chlorine, or C1-C4alkoxy, in particular for methoxy, Y stands for -CH2- or -O-, R1 and R2, independently from each other, stand for hydrogen, C1-C8alkyl, or C6-C14aryl, which may be substituted up to three times with C1-C8alkyl, C1-C4alkoxy or halogen, a process for their preparation and their use as fluorescent compounds, in particular as solid fluorescent compounds, such as for special effect printing, security printing or in the opto-electronic field.
