Title (EN) POLYMER EMULSION
(FR) ÉMULSION POLYMÈRE
(JA) ポリマーエマルション
Abstract:
(EN) The present invention pertains to a polymer emulsion capable of exhibiting scratch resistance even when a coating film is formed or when recording is performed on a recording medium having low liquid absorption, and a water-based ink for inkjet recording having exceptional ejection stability and bleed resistance during inkjet recording. [1] A polymer emulsion containing a polymer and water, wherein the polymer is a random copolymer or a block copolymer containing (a) structural units derived from one or more monomers selected from acrylic acid and methacrylic acid and (b) structural units derived from a hydrophobic vinyl monomer, the polymer moreover is a carboxy-group-containing polymer having an acid value of 150-300 mg KOH/g, and the polymer emulsion includes a compound that releases formaldehyde. [2] A water-based ink for inkjet recording, the water-based ink containing a pigment, the polymer, a water-soluble organic solvent, and water, wherein the water-soluble organic solvent includes one or more compounds selected from polyhydric alcohols and polyhydric alcohol alkyl ethers, the total amount of polyhydric alcohols and polyhydric alcohol alkyl ethers is 18% by mass or greater in the ink, and the water-based ink for inkjet recording includes a compound that releases formaldehyde.
(FR) La présente invention concerne une émulsion polymère capable de faire preuve de résistance aux rayures même quand un film de revêtement est formé ou quand une impression est effectuée sur un support d'impression à faible absorption de liquide, et une encre à base d'eau pour l'impression à jet d'encre ayant une stabilité d'éjection et une résistance au dégorgement exceptionnelles pendant l'impression par jet d'encre. [1] Émulsion polymère contenant un polymère et de l'eau, où le polymère est un copolymère statistique ou un copolymère séquencé contenant (a) des motifs structuraux dérivés d'un ou plusieurs monomères choisis parmi l'acide acrylique et l'acide méthacrylique et (b) des motifs structuraux dérivés d'un monomère de vinyle hydrophobe, et le polymère est en outre un polymère contenant un groupe carboxy ayant un indice d'acide de 150 à 300 mg de KOH/g, et l'émulsion polymère contient un composé qui libère du formaldéhyde. [2] Encre à base d'eau pour l'impression par jet d'encre, où l'encre à base d'eau contient un pigment, le polymère, un solvant organique hydrosoluble, et de l'eau, où le solvant organique hydrosoluble comprend un ou plusieurs composés choisis parmi les alcools polyhydriques et les éthers alkyliques d'alcools polyhydriques, la quantité totale d'alcools polyhydriques et d'éthers alkyliques d'alcool polyhydrique dans l'encre est de 18 % en poids ou plus, et l'encre à base d'eau pour l'impression à jet d'encre comprend un composé qui libère du formaldéhyde.
(JA) 塗膜を形成した場合や低吸液性の記録媒体に記録した場合にも、耐擦過性を発揮することができるポリマーエマルション、及びインクジェット記録時の吐出安定性、耐ブリード性に優れるインクジェット記録用水系インクに関する。 [1]ポリマー及び水を含有するポリマーエマルションであって、ポリマーが、(a)アクリル酸及びメタクリル酸から選ばれる1種以上のモノマー由来の構成単位と、(b)疎水性ビニルモノマー由来の構成単位を含有するランダム共重合体又はブロック共重合体であって、その酸価が150~300mgKOH/gであるカルボキシ基含有ポリマーであり、ホルムアルデヒドを放出する化合物を含む、ポリマーエマルション、及び[2]顔料、前記ポリマー、水溶性有機溶媒、及び水を含有するインクジェット記録用水系インクであって、水溶性有機溶媒が、多価アルコール及び多価アルコールアルキルエーテルから選ばれる1種以上の化合物を含み、多価アルコールと多価アルコールアルキルエーテルの合計量が、インク中、18質量%以上であり、ホルムアルデヒドを放出する化合物を含む、インクジェット記録用水系インクである。
