The present invention is concerned with compounds of formula (I) ##STR1## wherein m is 0 or 1; W is hydrogen, a C.sub.1-16 straight, branched, or cyclic alkyl group, or a C.sub.2-16 straight, branched, or cyclic alkenyl or alkynyl group, or Ph(CH.sub.2).sub.n -- where Ph is phenyl and n is an integer of from 0 to 2, the phenyl group being optionally substituted by one or more atoms or groups independently selected from halogen, hydroxy, nitro, C.sub.1-4 alkoxy and C.sub.1-4 alkyl wherein one or more of the hydrogen atoms in said alkyl group is optionally replaced by halogen, or R.sup.1 NHCO-- where R.sup.1 is hydrogen or a C.sub.1-6 alkyl group, or R.sup.2 CONH-- where R.sup.2 is hydrogen or a C.sub.1-6 alkyl group; X is ##STR2## where A is halogen; Y is --(CH.sub.2).sub.q, where q is an integer of from 1 to 3, or --CH.dbd.CH-- (E or Z); Z is a C.sub.1-6 alkyl group optionally substituted by one or more independently selected polar groups; and ring A is optionally substituted by one or more atoms or groups independently selected from halogen, hydroxy, nitro, C.sub.1-4 alkoxy and C.sub.1-4 alkyl wherein one or more of the hydrogen atoms in said alkyl group is optionally replaced by halogen.
