Claim 0:
1. A storage-stable, isocyanate group-containing formulation comprising the components:
a. 0.01% to 45% by weight of at least one pigment;
b. 0% to 99% by weight of at least one isocyanate group-containing component which has free isocyanate groups;
c. 0.01% to 20% by weight of at least one wetting agent and/or dispersant;
d. 0.1% to 35% by weight of at least one isocyanate group-containing grinding resin comprising free isocyanate groups; and
e. 0% to 80% by weight solvents,
in each case based on a total amount of the formulation, with the sum of all constituents
in the formulation not exceeding 100% by weight,, wherein the formulation after storage at 50° C. over a period of at least 3 days exhibits a rise in viscosity of less than 500%, based on a starting viscosity of the formulation which is determined as of 1 hour after combining all of the components, wherein the viscosity determination is carried out in each case at 20° C. at a shear rate of 500 [ 1/s], wherein a molar ratio of the sum of all isocyanate groups of the isocyanate group-containing formulation to a sum of all isocyanate-reactive groups which are not isocyanate groups in the formulation is at least 8:1, wherein the isocyanate group-containing grinding resin d. has a viscosity in a range from 100 to 5000 mPas, and wherein the isocyanate group-containing grinding resin d. is selected from the group consisting of 1,4-iisocyanatobutane (BDI), 1,5-diisocyanatopentane (PDI), 1,6-diisocyanatohexane (HDI), 2-methyl-1,5-diisocyanatopentane, 1,5-diisocyanato-2,2-dimethylpentane, 2,2,4- and/or 2,4,4-trimethyl-1,6-diisocyanatohexane, 1,10-diisocyanatodecane, 1,3- and/or 1,4-bis(isocyanatomethyl)benzene (XDI), 1,3- and/or 1,4-bis(1-isocyanato-1-methylethyl)benzene (TMXDI), 2,4- and/or 2,6-diisocyanatotoluene (TDI), 2,4′- and/or 4,4′-diisocyanatodiphenylmethane (MDI), 1,5-diisocyanatonaphthalene, 1-isocyanato-3,3,5-trimethyl-5-isocyanatomethylcyclohexane (IPDI), 1-isocyanato-1-methyl-4(3)-isocyanatomethylcyclohexane, 2,4′- and/or 4,4′-diisocyanatodicyclohexylmethane (H12MDI), a mixture of at least two of these, and optionally oligomers and reaction products of these.
