摘要：The present invention is directed to an organic polyurethane compositionhaving a solids content of about 10 to 100 weight percent which comprises
(1) isocyanate-terminated prepolymers which are prepared by reacting reactionproducts of the phosgenation of aniline-formaldehyde condensates containing specificratios of isomers and homologues with polyether polyols containing at least twohydroxyl groups and at least one tertiary nitrogen atom and, optionally, an additionalpolyol which does not contain a tertiary nitrogen atom and optionally,
< P>(2) a monoisocyanate comprising a member selected from para-toluenesulfonylisocyanate and the reaction product of 2,4- or 2,6-toluene diisocyanate or mixturesthereof with specific monoalcohols.
The present invention is also directed to the coatings produced from thepolyurethane compositions, optionally containing pigments.
