  • ##STR47## wherein;

    R2, R3, R4 and R5 can be the same or different and are hydrogen or an alkyl group containing up to 3 carbon atoms, and R and R1 can be the same or different and are;

    (a) hydrogen(b) an alkyl group containing up to 6 carbon atoms(c) a cycloalkyl group containing 5 to 8 carbon atoms(d) a cyano group(e) a nitro group(f) --R10 COXR3 wherein R10 is a single covalent bond or a divalent aliphatic acyclic hydrocarbyl group containing 1 to 3 carbon atoms, X is divalent sulfur or oxygen, and R6 is(i) an alkyl, alkenyl or alkynyl group containing up to 12 carbon atoms(ii) a cycloalkyl or cycloalkenyl group containing 5 to 8 carbon atoms(iii) an aryl, aralkyl, alkyl substituted aralkyl, or alkaryl group containing 6 to 10 carbon atoms(iv) an hydroxyalkyl, alkoxyalkyl, arkylaminoalkyl, or aralkylaminoalkyl group containing up to 10 carbon atoms(g) --R10 COR7 where R10 has the meaning specified in (f) and wherein R7 is;
