Title (EN) CELLULOSE-BASED ORGANIC PIGMENTS
(FR) PIGMENTS ORGANIQUES À BASE DE CELLULOSE
Abstract:
(EN) A pigment comprising dyed crystalline cellulose particles comprising a crystalline cellulose core having a surface charge, optionally one or more polyelectrolyte layers with alternating charges adsorbed on top of each other on the crystalline cellulose core, the polyelectrolyte layer closest to the core having a charge opposite the surface charge of the core, and at least one organic dye having a charge is provided.
(FR) La présente invention concerne un pigment comprenant des particules de cellulose cristalline teintes comprenant un noyau de cellulose cristalline ayant une charge de surface, facultativement une ou plusieurs couches de polyélectrolytes à charges alternées adsorbées les unes sur les autres sur le noyau de cellulose cristalline, la couche de polyélectrolytes la plus proche du noyau ayant une charge opposée à la charge de surface du noyau, et au moins un colorant organique ayant une charge.
