发明名称 PROCESSO PER RIDURRE IL CAMBIAMENTO DI COLORE NEI SISTEMI COPIATIVI SENZA CARBONE E RELATIVO PRODOTTO
摘要 <p>Disclosed is a process for preparing improved microcapsules which are useful in connection with carbonless copying systems. Also disclosed are the microcapsules themselves which comprise minute discrete droplets of liquid fill material including an initially colorless chemically reactive color forming dye precursor and a carrier therefor encapsulated within individual, rupturable, generally continuous polyamide shells formed thereabout. The process comprises the step of incorporating in the fill material, an amount of an epoxy resin or a polystyrene resin effective to render the microcapsules resistent to inadvertent release and transfer of the fill material.</p>
