Abstract: The present invention provides two-component polyurethane compositions comprising, as one component, polyisocyanate compositions of the isocyanurate of one or more bis(isocyanatomethyl)cyclohexane or, preferably, a mixture of two or more of these, and of the isocyanurate of hexamethylene diisocyanate (HDI trimer), and, as the other component, a mix of a soft polyol having a hydroxyl functionality of from 2.5 to 5.0 and a molecular weight of from 500 to 3,000, and a hard polyol. Such compositions provide coatings, especially clear topcoats, which exhibit excellent scratch and mar and solvent resistance in addition to a good balance of hardness and flexibility without the need for increasing the volatile organic content (VOC) of the compositions. Also provided are compositions of a polyisocyanate compositions of the isocyanurate of one or more bis(isocyanatomethyl)cyclohexane with soft polyol which have lower VOCs.

Abstract: An ink composition includes a particulate pigment, a hydrocarbon vehicle, an organic polyamine and an organic polyacid. A ratio by weight percent of the organic polyamine to the organic polyacid in the hydrocarbon vehicle is sufficient to render a conductivity of the ink composition to equal to or less than 15 nanosiemens per centimeter. The ink composition is prepared by combining the particulate pigment with a composition that includes the hydrocarbon vehicle, the organic polyamine and the organic polyacid. The combination is subjected to conditions under which the particulate pigment becomes dispersed in the composition.
