a curing agent (1) into
a reaction product (2), being essentially free from carboxy and/or anhydride groups, of
i) at least one glycidylether of a polyhydric phenol, and
ii) at least one functionalized selectively hydrogenated block copolymer B to which has been grafted carboxy and/or anhydride functional groups said functionalized block copolymer comprising
