The amount of unreacted 1-isocyanato-3,3,5-trimethyl-5-isocyanatomethyl-cyclohexane (IPDI) mixed with an adduct of IPDI and a polyhydroxyl compound having two or three hydroxyl groups in a solution thereof in a conventional lacquer solvent is reduced by mixing the solution with from 0.1 to 10 mols monohydric alcohol per mol of unreacted IPDI in the solution to provide a polyisocyanate solution adapted for use in making coating materials such as lacquers.
