Abstract (en)
[origin: WO8602350A1] A new and useful class of ultra light absorbing compounds and their use in sunscreen compositions and the protection of paint films and plastics materials from solar degradation. In particular the compounds possess a novel UV absorbing chromophore of structure (I). It has been found that the oxygen substituent at the 2 position is essential to the invention. Preferred compounds of the invention have formulae (I) or (II), wherein R1 is selected from hydrogen, alkyl or alkenyl; NR2 is an amino group or a secondary or tertiary amine moiety in which the N atom bears either one or two unsubstituted or substituted alkyl, aryl or alkenyl groups which may be the same or different when two are present; R is a moiety selected from alkyl, substituted alkyl, hydroxyl, carboxylic acid, ester or ether at positions 4, 5 or 6 on the ring; n is 0-4.
