A process for preparing liquid lacquer polyisocyanates with aliphatically and aromatically bound isocyanate groups and an NCO content of 5 to 25 wt. % by trimerizing an isocyanate component A), containing A1) 70 to 100 wt. % of diisocyanatotoluene and A2) 0 to 30 wt. % of other aromatic isocyanates and B) aliphatic lacquer polyisocyanates, optionally with prior, simultaneous and/or subsequent reaction of a portion of the isocyanate groups with an alcohol component C) having a molecular weight of 32 to 900, and optionally in the presence of D) inert solvents; the resulting lacquer polyisocyanates; and their use in coating compositions, in particular as a cross-linking agent for polyhydroxyl compounds in two-component polyurethane coating compositions.
