    (C) one, or more oligomers (C);
    (D) one, or more photoinitiators (D);
    (E) at least a surfactant (E), which is a block copolymer, comprising at least a block A and a block B, wherein
    a) the block A comprises
    a1) monomer units (A1) derived from a compound selected from alkyl (meth)acrylates, alkyl (meth)acrylamides, or any mixture thereof, and
    a2) monomer units (A2) derived from a hydroxy group, or ether group containing alkyl (meth)acrylate;
    b) the block B comprises monomer units (B) derived from a compound selected from fluorinated (meth)acrylic esters of formula






    H2C═CR46(C(O)ORF-1)  (XX), wherein



    R46 is H, or a methyl group; and
    RF-1 is an organic residue containing a perfluorinated alkyl group;
