Dependent claims

An aqueous dipping composition for coating a textile reinforcing material, comprising

4.5% to 25% by dry weight of at least one rubber latex,
0.2% to 4.5% by dry weight of at least one blocked isocyanate,
0.3% to 15% by dry weight of at least one filler,
0% to 4% by dry weight of at least one epoxy group-containing compound, and
0% to 2% by dry weight of at least one polymer with carboxylic acid functional groups,
wherein the amounts in % by dry weight are based on the total weight of the aqueous dipping composition,
wherein the weight ratio of rubber latex to the sum of blocked isocyanate, epoxy group-containing compound and polymer with carboxylic acid functional groups is at least 2, and
wherein the composition is essentially free of resorcinol, resorcinol precondensates, formaldehyde and formaldehyde-releasing substances.
