In the formulae, R1=1-20C alkyl; R2= H or 1-20C alkyl; A=2-20C tert. aliphatic amine, or a heterocyclic gp. with 5-6 atoms, of which at least 1 is N and the others are C, N, S and/or O, opt. substd. by 1-3 1-4C alkyl or 2-4C alkenyl gps. or 1-2 Ph and opt. condensed with 1 or 2 aromatic or heterocyclic gps. with 5-6 atoms.
