present invention that the urethane substituted dye and or colorant can be design engineered to obtain desired properties for specific printing platforms and architectures it is also an advantage though not a requirement of the present invention that the urethane substituted dye and or colorant is very pure being free of salts and other insoluble contaminants it is another advantage of the present invention that the urethane substituted dye and or colorant can be used in combination with other ink carrier materials to obtain ink compositions that possess excellent spectral strengths it is still another advantage though not a requirement of the present invention that the urethane substituted dye and or colorant is substantially transparent these and other aspects features and advantages are obtained by the use of such inventive intermediates such as urethane substituted anilines to form such substituted colorants that are suitable for use with waxes and or oils in phase change ink jet inks and offset inks that may be employed in direct or indirect printing applications it has been found that the reaction of isocyanates with oxyalkylenated aniline compounds and other reactants as discussed above ultimately results in the formation of a dye and or colorant substantially modified by the reaction of the nucleophilic hydroxyl groups of the intermediate and substantially free of unmodified insoluble impurities which are completely compatible in wax and or oil systems the structures ii iii and iv above are merely preferred embodiments of such a broad range of possible dyes and or colorants as noted above such novel intermediates permit production of colorants made therefrom that are substantially modified by the reaction of the nucleophilic hydroxyl groups with isocyanates a low amount of.
