Abstract: Polyisocyanate composition containing



(A) at least one polyisocyanate obtainable by reacting at least one monomeric isocyanate,
(B) at least one solvent containing a mixture of C7-C14 aromatic hydrocarbons,
(C) optionally at least one further solvent,
(D) optionally at least one Lewis-acidic organic metal compound capable of accelerating the reaction of isocyanate groups with isocyanate-reactive groups,
(E) optionally other coatings additives,

wherein the amount of cumene in component (B) is less than 1 wt %, preferably less than 0.7 wt %.
