Claim 1

A compound having the formula ##STR137## wherein p is 1, 2 or 3; and q is 0, 1 or 2 provided that p+q≦3; R is a group of the formula ##STR138## and when p is 2 or 3, each group R may be the same or different and is present in the 2-, 4- or 6-position; n is an integer from 2 to 30; K is 1 or 2; Q is --COOR 4 or --CONR 4 R 5 wherein R 4 is (1) H; (2) a straight or branched chain alkyl having from 1 to 20 carbon atoms; (3) divalent straight or branched chain alkylene having 2-20 carbon atoms; (4) a straight or branched chain alkenyl group having from 3 to 20 carbon atoms, (5) a cycloalkyl group having from 3 to 12 carbon atoms; (6) an aryl group having from 6 to 10 carbon atoms which is unsubstituted or is substituted by a C 1 -C 4 alkyl group; (7) an aralkyl group having from 7 to 13 carbon atoms; provided that when k is 2, the two carbon atoms to which the --COOR 4 groups are attached are not adjacent to one another; and R 5 is hydrogen or a straight or branched chain alkyl group having from 1 to 20 carbon atoms, or R.sup. 4 or R 5 together with the nitrogen atom to which they are each bonded may form a pyrrolidine, piperidine, morpholine or 2,5-dimethyl morpholine; R 2 and R 3 are the same or different and each is straight or branched chain alkyl group having from 1 to 5 carbon atoms and, when Q is CO 2 R 4 , either R 2 or R 3 is optionally substituted by a --CO 2 R 4 group, the R 4 groups being independent, or R 2 or R 3 may be so linked to the residue C n H 2n+1-k that there is formed a C 5 -C 12 cycloalkylene residue substituted by the group --(CO 2 R 4 ) k , the R 4 groups being independent, wherein R 4 and k are as previously defined; R 1 is a C 1 -C 12 straight or branched chain alkyl group, a C 7 -C 9 aralkyl group, halogen, CF 3 , SH, SR 13 , CO 2 H, CO 2 R.sup. 13, COR 13 , COC 6 H 5 , CONH 2 , CN, SO 3 H, SO 2 NH 2 , PO(OH) 2 , PO(OR 13 ) 2 , or NO 2 wherein R 13 is a C 1 -C 4 straight or branched chain alkyl group, and, when O is 2, each R 1 group may be the same or different; and provided that, when p is 1, R 1 is C 1 -C 12 alkyl, R 2 and R 3 are C 1 -C 5 alkyl, k is 1, O is --COOR 4 wherein R 4 is H, and q is as previously defined, then n is not 2; and further provided that when k is 2 and p is 1 and the group R is in the para-position to the phenolic OH, then in such case (a) when O is --COOR 4 , R 4 is other than straight or branched chain alkyl and unsubstituted or substituted phenyl, and (b) when O is --CONR 4 R 5 , R 4 and R 5 are not both H; or a salt thereof with an organic or inorganic acid or base.
