COMB-LIKE POLYETHERALKANOLAMINES IN INKS AND COATINGS

摘要

Provided herein are compositions useful as ink or coatings which contain novel dispersants that are capable of dispersing pigments which are traditionally difficult to disperse while maintaining acceptable levels of viscosity. Use of dispersants as taught herein enables the preparation of a wide variety of inks and coatings having high pigment loading and existing within a conventionally-useful viscosity range.

主权项

1. A composition comprising:
a) a pigment component; b) an effective pigment-dispersing amount of a dispersant having the structure: in which R1 may be any C1-C100 hydrocarbyl group; R2 may be any alkoxylated hydrocarbyl group defined by the structure:in which R3 is selected from the group consisting of: hydrogen, and any C1 to about C24 hydrocarbyl group; X1, X2, X3, X4, X5, and X6 in each occurrence are independently selected from the group consisting of: hydrogen, methyl and ethyl, subject to the proviso that at least one of the two X groups that are attached to the same alkoxy unit are hydrogen, p, q, and r may each independently be any integer between zero and about 100, including zero, subject to the proviso that at least one of p, q, and r is not zero; n is any integer between 1 and about 50; and s may be either 0 or 1; and
c) a grind resin.
