Title
(EN) METHOD FOR PRODUCING AQUEOUS PIGMENT DISPERSION
(FR) PROCÉDÉ DE PRODUCTION D'UNE DISPERSION PIGMENTAIRE AQUEUSE
(JA) 顔料水分散体の製造方法
Abstract
(EN) The present invention relates to: [1] a method for producing an aqueous pigment dispersion, which comprises a step 1 for obtaining an aqueous dispersion (C) by mixing an aqueous dispersion (A), in which a pigment (I) is dispersed by means of a water-dispersible polymer, and an aqueous dispersion (B) of an autodispersible pigment (II), and a step 2 for obtaining an aqueous pigment dispersion by subjecting the aqueous dispersion (C), which has been obtained in step 1, to a heat treatment at 40°C or higher; and [2] an aqueous pigment dispersion which contains a pigment (I) that is dispersed by means of a water-dispersible polymer and an autodispersible pigment (II), and wherein the water-dispersible polymer is adsorbed onto the pigment (I) and the autodispersible pigment (II).
(FR) La présente invention concerne : [1] un procédé de production d'une dispersion pigmentaire aqueuse, qui comprend une étape 1 pour obtenir une dispersion aqueuse (C) par mélange d'une dispersion aqueuse (A), dans laquelle est dispersé un pigment (I) au moyen d'un polymère dispersible dans l'eau, et d'une dispersion aqueuse (B) d'un pigment autodispersible (II) et une étape 2 pour obtenir une dispersion pigmentaire aqueuse par la soumission de la dispersion aqueuse (C), qui a été obtenue dans l'étape 1, à un traitement thermique à 40°C ou plus ; et [2] une dispersion pigmentaire aqueuse qui contient un pigment (I) qui est dispersé au moyen d'un polymère dispersible dans l'eau et un pigment autodispersible (II), le polymère dispersible dans l'eau étant adsorbé sur le pigment (I) et sur le pigment autodispersible (II).
(JA) [1]顔料(I)を水分散性ポリマーで分散した水分散体(A)と、自己分散型顔料(II)の水分散体(B)を混合して、水分散体(C)を得る工程1と、工程1で得られた水分散体(C)を40℃以上で加熱処理して顔料水分散体を得る工程2を有する顔料水分散体の製造方法、[2]水分散性ポリマーで分散した顔料(I)と、自己分散型顔料(II)とを含有し、顔料(I)及び自己分散型顔料(II)に該水分散性ポリマーが吸着してなる、顔料水分散体に関する。
