Title (EN) PAPER COATING COMPOSITION AND PROCESSES OF MAKING THEREOF
(FR) COMPOSITION DE REVÊTEMENT DE PAPIER ET PROCESSUS DE FABRICATION CORRESPONDANTS
Abstract:
(EN) A novel coating composition comprises an aqueous dispersion of a binder;pigment;starch;and a hydrophobically modified alkali-swellable emulsion which comprises structural units of a carboxylic acid monomer, an acrylate monomer, and a polyethoxylated aralkyl phenol methacrylate. This novel coating composition provides improved thickening efficiency.
(FR) Une nouvelle composition de revêtement comprend une dispersion aqueuse d'un liant; un pigment; de l'amidon; et une émulsion pouvant gonfler dans un alcali modifiée de manière hydrophobe qui comprend des unités structurales d'un monomère d'acide carboxylique, d'un monomère d'acrylate et d'un méthacrylate de phénol d'aralkyle polyéthoxylé. Cette nouvelle composition de revêtement présente une efficacité d'épaississement améliorée.
