Claim:
A composition comprising: (i) at least one component A comprising a compound selected from the group consisting of imidazo[1,5-a]pyrimidinium derivatives of general formula I, enamine counterparts of imidazo[1,5-a]pyrimidinium derivatives of the general formula I, and mixtures thereof: wherein R 1 represents a substituent selected from the group consisting of a hydrogen atom, a halogen atom, a carboxyl group, a (C 1 -C 6 ) alkoxy group, a (C 1 -C 6 ) alkyl group, a (C 2 -C 6 ) alkenyl group, an optionally substituted aryl group, an aryl (C 1 -C 6 ) alkyl group, a (C 2 -C 6 ) hydroxyalkyl group, a (C 2 -C 6 ) polyhydroxyalkyl group, and a R I R II N—CO— group, wherein R I and R II each independently represent a substituent selected from the group consisting of a hydrogen atom, a (C 1 -C 6 ) alkyl group, a (C 1 -C 6 ) alkenyl group, an aryl group, and an aryl C 1 -C 6 alkyl group, and wherein R I and R II together with the nitrogen atom in the R I R II N—CO— group can form a 5-7 membered ring; wherein R 2 represents a substituent selected from the group consisting of a (C 1 -C 6 ) alkyl group, a (C 2 -C 6 ) alkenyl group, an optionally substituted aryl group, an aryl (C 1 -C 6 ) alkyl group, a (C 1 -C 6 ) hydroxyalkyl group, a (C 2 -C 6 ) polyhydroxyalkyl group, and a R III R IV N—(CH 2 ) n — group, wherein R III and R IV each independently represent a hydrogen atom, a (C 1 -C 6 ) alkyl group, a (C 1 -C 6 ) alkenyl group, and an aryl C 1 -C 6 alkyl group, and wherein R III and R IV together with the nitrogen atom in the R III R IV N—(CH 2 ) n — group can form a 5-7 membered ring, and wherein n represents and integer of 2 to 6; wherein R 3 and R 5 each independently represents a substituent selected from the group consisting of a hydrogen atom, a (C 1 -C 6 ) alkyl group, a (C 2 -C 6 ) alkenyl group, an aryl group, an aryl (C 1 -C 6 ) alkyl group, a (C 2 -C 6 ) hydroxyalkyl group, and a (C 2 -C 6 ) polyhydroxyalkyl group, with the proviso that at least one of R 3 and R 5 represents a methyl group; wherein R 4 represents a substituent selected from the group consisting of a hydrogen atom, a (C 1 -C 6 ) alkyl group, a (C 2 -C 6 ) alkenyl group, a (C 1 -C 6 ) hydroxyalkyl group, a (C 2 -C 6 ) polyhydroxyalkyl group, and an optionally substituted aryl group; and wherein X − represents a physiologically compatible anion; and (ii) at least one component B comprising a reactive carbonyl compound.
