Abstract
A new particulate nitrocellulose composition comprises nitrocellulose and 10 - 30% by weight of a hydroxylic plasticizer containing at least one free hydroxyl group. A protective water-soluble colloid is used to prepare the compositions. The compositions are particularly valuable for the manufacture of polyurethane lacquers, and improve the resistance of the lacquers to solvents and to migration of plasticizers.
