Claim 1

A compound having the following general structure: ##STR3## wherein R, R 1 , R 2 and R 3 are independently selected from the group consisting of hydrogen; alkyl and chlorinated alkyl each having from 1 to 17 carbon atoms; alkenyl radicals having from 2 to 17 carbon atoms; phenyl, naphthyl, substituted phenyl and substituted naphthyl radicals having no more than two substitutents selected from the group consisting of --Cl, --OH, --OR 5 and --NR 5 R 6 wherein R 5 and R 6 are alkyl radicals having 1 to 8 carbon atoms; not more than one of R and R 1 or of R 2 and R 3 is phenyl, naphthyl, substituted phenyl, substituted naphthyl, t-alkyl or t-alkenyl; n is an integer of from 1 to 4; R 4 is selected from the group consisting of (a) --NR 7 R 8 wherein R 7 and R 8 are independently selected from alkyl radicals having from 1 to 18 carbon atoms and together having a total of at least 5 carbon atoms, (b) --NZ which represents a morpholino or piperidino radical, and (c) ##STR4## wherein R 9 , R 10 , R 11 and R 12 are independently selected from the same group from which R is selected and at least one of R 9 , R 10 , R 11 and R 12 is other than hydrogen; and X and X' are independently selected from oxygen and sulfur atoms.
