Title (EN) AQUEOUS PIGMENT DISPERSION
(FR) DISPERSION AQUEUSE DE PIGMENT
(JA) 顔料水分散体
Abstract:
(EN) The present invention relates to an aqueous pigment dispersion which comprises a pigment, a crosslinked polymer, and water, wherein the crosslinked polymer has been obtained by crosslinking a carboxylated polymer with a crosslinking agent and has an acid value of 70-300 mg-KOH/g, the aqueous pigment dispersion containing a compound which releases formaldehyde. The aqueous pigment dispersion has excellent storability even in long-term storage at high temperatures.
(FR) La présente invention concerne une dispersion aqueuse de pigment comprenant un pigment, un polymère réticulé et de l'eau, le polymère réticulé ayant été obtenu par réticulation d'un polymère carboxylé avec un agent de réticulation et présentant une valeur acide de 70 à 300 mg-KOH/g et la dispersion aqueuse de pigment contenant un composé qui libère du formaldéhyde. La dispersion aqueuse de pigment a une excellente aptitude au stockage même à long terme et à des températures élevées.
(JA) 顔料、架橋ポリマー、及び水を含有する顔料水分散体であって、架橋ポリマーがカルボキシ基を有するポリマーを架橋剤で架橋してなり、その酸価が70mgKOH/g以上300mgKOH/g以下であり、顔料水分散体中にホルムアルデヒドを放出する化合物を含み、高温で長期間保管しても、保存安定性に優れる顔料水分散体に関する。
