Abstract:
The use of non aqueous dispersions NADs has enabled the development of fast setting sheet fed inks, for example. However either due to residual monomers or fractions of initiators, these NAD's have an objectionable odor. A chemical means of dramatically reducing the odor of the NAD's is thus presented. In exemplary embodiments of the present invention, such a chemical treatment can include an amine/alkali mixture in a coupling solvent. In exemplary embodiments of the present invention, the coupling solvent can be one or more of an alcohol, glycol or glycol ether, such as, for example, isopropyl alcohol. In exemplary embodiments of the present invention the amine can be an alkyl amine, such as, for example, diethyl amine, or various other amines, whether alone or in combination. In exemplary embodiments of the present invention, the alkali can be one or more of sodium hydroxide, potassium hydroxide and ammonium hydroxide, whether alone or in any combination thereof.
