Title
(EN) A COMPOSITION FOR SURFACE COLOURATION OF PAPER
(FR) COMPOSITION POUR LA COLORATION DE PAPIER EN SURFACE
Abstract
(EN)
The invention relates to a composition for surface colouration of paper web comprising a) from 0.1 to 30% by weight, based on the total weight of the composition, of a colouring pigment, b) from 0.1 to 20% by weight, based on the total weight of the composition of a starch/latex copolymer, characterized in that, in addition to starch, the monomeric components that are copolymerized comprise i) styrene or a substituted styrene, ii) an acrylate and/or methacrylate and, optionally, iii) one or more further ethylenically unsaturated monomers, c) from 0 to 20% by weight, based on the total weight of the composition, of starch or a starch derivative, d) from 0 to 10% by weight, based on the total weight of the composition of one or more auxiliaries and e) water to complete to 100% by weight, based on the total weight of the composition.
(FR)
L'invention concerne une composition pour la coloration en surface d'une feuille de papier continue comprenant a) de 0,1 à 30 % en poids, sur la base du poids total de la composition, d'un pigment colorant, b) de 0,1 à 20 % en poids, sur la base du poids total de la composition, d'un copolymère d'amidon/latex, caractérisée en ce que, en plus de l'amidon, les composants monomériques qui sont copolymérisés comprennent i) du styrène ou un styrène substitué, ii) un acrylate et/ou un méthacrylate et, éventuellement, iii) un ou plusieurs autres monomères à insaturation éthylénique, c) de 0 à 20 % en poids, sur la base du poids total de la composition, d'amidon ou d'un dérivé de l'amidon, d) de 0 à 10 % en poids, sur la base du poids total de la composition, d'un ou plusieurs adjuvants et e) de l'eau pour compléter à 100 % en poids, sur la base du poids total de la composition.
