The invention concerns bi-aromatic compounds of formula (I) in which Ar represents (a), Z being O or S, R.sub.1 is --CH.sub.3, --CH.sub.2 --O--R.sub.6, --OR.sub.6 or --COR.sub.7 ; R.sub.2 is --OR.sub.8, --SR.sub.8 or a polyether radical if in the latter case R.sub.4 is C.sub.1 -C.sub.20 alkyl and is in ortho or meta position relative to X--Ar; R.sub.3 is alkyl or R.sub.2 and R.sub.3 together form a cycle optionally interrupted by O or S; R.sub.4 is aryl radical; R.sub.5 is H, halogen, C.sub.1 -C.sub.20 alkyl or --OR.sub.8 ; R.sub.6 is H, alkyl or --COR.sub.9 ; R.sub.7 is H, alkyl, --N(r')(r") or --OR.sub.10 ; R.sub.8 is H, alkyl or --COR.sub.9 ; R.sub.9 is alkyl; R.sub.10 is H, C.sub.1 -C.sub.20 alkyl, alkenyl, monohydroxyalkyl or polyhydroxyalkyl, aryl or aralkyl or a sugar residue, r' and r" are H, alkyl mono- or polyhydroxyalkyl, aryl, an amino acid or sugar residue or together form a heterocycle, X represents a radical of formula (d) or (e) in which R.sub.11 is H or --OR.sub.6 ; R.sub.12 is H or alkyl; or R.sub.11 and R.sub.12 form an oxo radical, and the salts, optical and geometrical isomers of the compounds of formula (I). ##STR1##
