    Abstract: Basic rhodamine dyes suitable for use in recording fluids for the ink jet process and for coloring paper stock have the formula where L is C2-C10-alkylene, R1, R2 and R3 are each independently of the others hydrogen, substituted or unsubstituted C1-C10-alkyl or C5-C7-cycloalkyl or R1 and R2 together with the nitrogen atom linking them together are a hetero cyclic radical, An~ is one equivalent of an anion and m and n are each independently of the other 0 or 1.

    Abstract: The invention relates to the use of benzaldehydes of the formula (I), in which ring A can be benzo-anellated and R , R and R are hydrogen, hydroxy, C1-C15 alkyl, C1-C15 alkoxy, cyano, nitro or a radical of the formula NR R or COOR , in which R is hydrogen or possibly substituted C1-C15 alkyl, R is possibly substituted C1-C15 alkyl or a radical of the formula L-NX X , in which L is C2-C8 alkylene and X and X are mutually independently C1-C6 alkyl or, together with the nitrogen atom bonding them, a heterocyclic radical, and R is hydrogen, possibly substituted C1-C15 alkyl or a radical of the formula L-NX X , in which L, X and X have the above meanings, as marking agents for hydrocarbons, a process for detecting these benzaldehydes in hydrocarbons and hydrocarbons containing the above benzaldehydes.

    Abstract: PCT No. PCT/EP92/00534 Sec. 371 Date Jul. 20, 1993 Sec. 102(e) Date Jul. 20, 1993 PCT Filed Mar. 11, 1992 PCT Pub. No. WO92/16878 PCT Pub. Date Oct. 1, 1992.Electrostatic toners contain a polymeric binder and, as a charge stabilizer, a compound of the formula where Z is C1-C20-alkyl which is unsubstituted or substituted by phenyl or Z is C5-C7-cycloalkyl or unsubstituted or substituted phenyl, X and Y are each cyano or a radical of the formula -CO-OR1, -CO-NR1R2 or -C-R3, where R2 is C1-C20-alkyl which is unsubstituted or substituted by phenyl or R1 is C5-C7-cycloalkyl, R2 is hydrogen or C1-C4-alkyl and R3 is C1-C20-alkyl which is unsubstituted or substituted by phenyl or R3 is C5-C7-cycloalkyl or unsubstituted or substituted phenyl, or X and Y together form a radical of the formula -CO-L-CO- or -CO-CH=C(CH3)-O-CO-, where L is C2-C4-alkylene, and cat(+) is one equivalent of a cation.
