Abstract
(EN)
A composition comprising a compound of formula (I): wherein R1 and R2 may be the same or different, and are independently selected from hydrogen; halogen; hydroxyl; C1-18 alkoxy; C1-18 alkyl; C1-18 cycloalkyl; a primary, secondary or tertiary amino group; -CN; -NO2; -CF3, -COOH, -COR3, - CONR32; a heterocyclic ring; a heteroaryl; and C6-12aryl optionally substituted with C1-18 alkoxy, -CN, -CF3, -NO2, halogen, or C1-18 alkyl; X1a, X2a, X3a, X4a, X1b, X2b, X3b and X4b are independently selected from C, N or S; and R3 and R4 may be the same or different and are independently selected from hydrogen, Ci_ 18alkyl, C6-12aryl and C1-18alkyl-C6-12aryl; or a compound of formula (II):
