The invention concerns bi-aromatic compounds of formula (I) in which Ar represents (a), (b) or (c); Z being O or S, R1 is -CH3, -CH2-O-R6, -OR6 or -COR7; R2 is -OR8, -SR8 or a polyether radical if in the latter case R4 is C1-C20 alkyl and is in ortho or meta position relative to X-Ar; R3 is alkyl or R2 and R3 together form a cycle optionally interrupted by O or S; R4 is H, halogen, C1-C20 alkyl, -OR8, a polyether or aryl radical; R5 is H, halogen, C1-C20 alkyl or -OR8; R6 is H, alkyl or -COR9; R7 is H, alkyl, -N(r')(r") or -OR10; R8 is H, alkyl or -COR9; R9 is alkyl; R10 is H, C1-C20 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 R11 is H or -OR6; R12 is H or alkyl; or R11 and R12 form an oxo radical, and the salts, optical and geometrical isomers of the compounds of formula (I).
