b) at least monomer b1) or initiator b2) or both as defined below :
b1) at least one vinylic, allylic or (meth)acrylic monomer, bearing an anionic group derived from strong acids with pKa
b2) at least one initiator, bearing the same anionic group as b1)

c) at least one hydroxy-functional vinylic, allylic or (meth)acrylic monomer
d) optionally, at least one carboxy-functional ethylenically unsaturated monomer

摘要： The invention relates to an aqueous coating composition, comprising :
a) an aqueous polymer dispersion with said polymer containing monomeric units of at least one di carboxylic acid monomer, bearing two carboxylic acid functional groups and said polymer remaining insoluble in water after neutralization and remaining in the form of dispersed polymeric particles having a mean particle size varying from 10 to 1000 nm,
b) a crosslinker selected from aminoacids bearing at least two amino functional groups capable of reacting with said carboxylic functional groups.
It also relates to its use in the treatment of flexible fibrous substrates, a method for and the coated or treated fibrous substrate.
