Abstract
Abstract Compositions of matter comprising a finely divided dispersion of a solid having a particle size of less than 20 microns in an organic liquid selected from the class consisting of hydrocarbons and halogenated hydrocarbons containing dissolved therein an adduct of one or more compounds from each of the following classes (A) AN ORGANIC COMPOUND CONTAINING TWO OR MORE ISOCYANATE GROUPS, (B) AN ORGANIC COMPOUND CONTAINING TWO OR MORE GROUPS WHICH ARE REACTIVE WITH ISOCYANATE GROUPS, AND (C) AN ADDITION POLYMER CONTAINING A HYDROXY GROUP, THE AMOUNT OF THE ADDUCT CORRESPONDING TO BETWEEN 5% AND 100% BY WEIGHT BASED ON THE WEIGHT OF THE SOLID, AND THE AMOUNT OF THE SOLID CORRESPONDING TO BETWEEN 5% AND 70% BY WEIGHT BASED ON THE TOTAL WEIGHT OF THE DISPERSION FOR USE IN THE PREPARATION OF INKS AND PAINTS.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
122 words
Composition of matter comprising a finely divided dispersion of a solid having a particle size of less than 20 microns in an organic liquid selected from the class consisting of hydrocarbons and halogenated hydrocarbons containing dissolved therein a reaction product obtained by chemical reaction of one or more compounds from each of the following classes: (a) an aliphatic, cycloaliphatic or aromatic hydrocarbon substituted by at least two isocyanate groups; (b) an aliphatic diol containing from 5 to 10 methylene groups, and (c) an addition polymer containing an hydroxy group consisting of the reaction product of an alkylene oxide with a phenol, an aliphatic alcohol or an aliphatic amine wherein such alcohol or amine contains a chain of at least 12 carbon atoms.
