- a treating agent selected from the group consisting of a cyclic urea substituted with at least one isocyanate reactive group, a free radical scavenger, a polymer acid, or a mixture thereof;
- and
- one or more amine components having a structure according to one of the formulae
- each of Ra and Rb independently being a random sequence of units R1 R2 and/or R3, for which
- R1 being
- R2 being
- R3 being
- each of said R4, R5, R6 and R7 individually are —H or —CH3;
- wherein Ra is comprising 3 to 17 nitrogen atoms, Rb is comprising 2 to 16 nitrogen atoms.
