Title (EN) INK COMPOSITION WITH PIGMENT PARTICLES HAVING A HYDROPHOBIC SURFACE
(FR) COMPOSITION D'ENCRE COMPRENANT DES PARTICULES DE PIGMENT AYANT UNE SURFACE HYDROPHOBE
Abstract: front page image
(EN)Provided in one example herein is a liquid electrophotographic ink composition. The composition comprises: a carrier fluid comprising a polymer; ink particles each comprising a non-aqueous polymeric resin and pigment particles distributed in the polymeric resin; and a charge director. The pigment particles comprise a metal oxide and have a hydrophobic surface. The hydrophobic surface comprises at least one of the following: (i) nanoparticles attached to each of the pigment particles, the nanoparticles comprising at least one of an oxide, a phosphate, and a nitrate; (ii) a coating disposed over each of the pigment particles, the coating comprising at least one of an oxide, a phosphate, and a nitrate; and (iii) a coating disposed over each of the pigment particles, the coating comprising at least one of a polymer and an oligomer.
(FR)La présente invention concerne, dans un exemple, une composition d'encre électrophotographique liquide. La composition comprend : un fluide vecteur comprenant un polymère; des particules d'encre comprenant chacune une résine polymère non aqueuse et des particules de pigment réparties dans la résine polymère; et un agent conférant une charge. Les particules de pigments comprennent un oxyde métallique et ont une surface hydrophobe. La surface hydrophobe comprend au moins l'un des éléments suivants : (i) des nanoparticules adhérant à chacune des particules de pigment, les nanoparticules comprenant un oxyde, un phosphate et/ou un nitrate; (ii) un revêtement disposé au-dessus chacune des particules de pigment, le revêtement comprenant un oxyde, un phosphate et/ou un nitrate; et (iii) un revêtement disposé au-dessus de chacune des particules de pigment, le revêtement comprenant un polymère et/ou un oligomère.
