Claim:
1. An epoxy resin composition (C), comprising: (i) from 30 to 90% by weight of at least one epoxy compound (E), based on the total weight of the composition (C); (ii) from 0 to 60% by weight of at least one curing agent, based on the total weight of the composition (C); (iii) from 0 to 15% by weight of at least one accelerator, based on the total weight of the composition (C); (iv) from 1 to 60% by weight of at least one first poly(aryl ether sulfone) polymer (PAES (I-1)), based on the total weight of the composition (C) and wherein said PAES (I-1) polymer comprises amine functional groups in an amount equal to or more than 200 μeq/g; and (v) from 1 to 60% by weight of at least one second poly(aryl ether sulfone) polymer (PAES (I-2)), based on the total weight of the composition (C), and wherein said PAES (I-2) polymer is different from the PAES (I-1) polymer and the PAES (I-2) polymer is a polyethersulfone of which more than 50% by weight of the recurring units are recurring units according to formula (K):  and the PAES (I-2) polymer comprises phenol OH functional groups in an amount equal to or more than 10 μeq/q.
