(FR) PIGMENT PLASTIQUE ABSORBANT AYANT UNE DENSITÉ D'IMPRESSION AMÉLIORÉE ET FEUILLE D'ENREGISTREMENT LE CONTENANT
Abstract: front page image
(EN)A core/shell particle is provided, comprising: a water-absorbent, dye-fixing polymeric core, comprising: (a) a multivalent cation and a polymerization product of a monoethylenically unsaturated carbonyl-group containing monomer; (b) a nitrogen-containing polymer; or (c) a combination of (a) and (b); and a water-insoluble, porous polymeric shell, surrounding all or a portion of said core. A paper sizing or coating composition which incorporates the core/shell particles is provided. Recording sheets which include the composition, methods of making the composition and recording sheets, and methods for making an image are provided.
(FR)L'invention concerne une particule cœur/écorce, comprenant : un cœur polymère de fixation de colorant, absorbant l'eau, comprenant : (a) un cation multivalent et un produit de polymérisation d'un monomère à teneur en groupe carbonyle, à insaturation monoéthylénique ; (b) un polymère contenant de l'azote ; ou (c) une combinaison de (a) et (b) ; et une écorce polymère poreuse, insoluble dans l'eau, entourant la totalité ou une partie dudit cœur. L'invention concerne également une composition de collage ou couchage de papier qui comprend les particules cœur/écorce. L'invention concerne aussi des feuilles d'enregistrement qui comprennent la composition, des procédés de fabrication de la composition et des feuilles d'enregistrement et des procédés de formation d'une image.
