摘要:
Specific core-shell binders and additives for use in ink-jet printing ink compositions are provided. One class of specific core/shell binders has the general formula [AmBnC′p]x, where A and B are hydrophobic components in which A exhibits a glass transition temperature Tg between about −150° and +25° C. and B exhibits a glass transition temperature greater than 25° C., C′ is a component that forms a hydrophilic or water-soluble component in the polymer chain, and has an ionic or non-ionic structure, m 40 wt %, and p
