Composition based on (meth)acrylate monomers

A crosslinkable two-component composition comprising:

• a component A comprising:
• a compound having one of the following formulae (Ia) or (Ib):
• wherein:
• each one among R1, R2, R3, R4, R5, R6, R7, R8, Ra and Rb represents, independently of each other, a radical chosen from the group consisting of a hydrogen or halogen atom, alkyl, cycloalkyl or aryl;
• Rf represents a perhaloalkyl or a haloalkyl;
• X− represents an anion;
• and
• at least one (meth)acrylate monomer M1 having one of the following formulae (II), (III), (IV) or (V):
• wherein:
• R9 represents H or methyl;
• R10 represents H, methyl or ethyl;
• p represents 0 or 1;
• and
• Z represents H, O, S, an alkyl group, a benzyl group, an aryl group or an alkoxy group;
• Y represents O, S, NH or CH2;
• is a single bond or a double bond,
• on condition that, when Z represents O, then the bond is a double bond;
• G is chosen from the group consisting of C4 to C20 alkyls, cycloalkyls, alkenyls, cycloalkenyls, alkylaryls, arylalkyls or aryls, said alkyls, cycloalkyls, alkenyls, cycloalkenyls, alkylaryls, arylalkyls and aryls being optionally substituted with an alkyl group, said group G being characterized in that it comprises no heteroatom;
• a component B comprising at least one amine compound chosen from polyamines, dihydropyridine compounds, and mixtures thereof
• wherein, when component A comprises a monomer M1 having the formula (II) and component B comprises an amine compound chosen from dihydropyridine compounds, then component A further comprises an organic or mineral acid having a pKa or a pKa1 ranging from 0.3 to 5.0, measured in water at 25° C.
