Abstract

The invention comprises compounds of formula <FORM:1104729/C2/1> wherein Z is H or halogen, X is halogen, OR, SR, SO2R or NR1R11, R is alkyl, aryl or aralkyl, R1 and R11 are alkyl or aralkyl or R1 is H, or NR1R11 may be a saturated heterocyclic nucleus, and Y is alkyl (possibly fluorinated), aralkyl or NR1R11, at least one of R, R1 and R11 being an aliphatic radical for making the molecule fast to diffusion. The compounds are prepared by reacting the correspondingly substituted aniline with phenyl 1-hydroxy-4-Z-2-naphthoate.
