摘要 |
<p>Hot-melt imaging compositions useful for solventless coating on paper substrates. The imaging compositions comprise imaging microcapsules having melamine-urea-formaldehyde condensation polymer shells and an organic liquid dye precursor dispersed in a hot-melt binder. The compositions can be coated on paper substrates by conventional coating techniques to provide carbonless papers.</p> |
