  The present invention provides a process for preparing a solid pigment composition for pigment ink comprising the steps of (a) dissolving polyvinyl alcohol in water, and dispersing pigments in the resulting solution; (b) adding aldehyde derivatives to the resulting pigment dispersion and allowing the polyvinyl alcohol to react with the aldehyde derivatives to prepare polyvinyl acetal; and (c) drying the acetalated pigment dispersion. The pigment ink resulted from the process, employs water-soluble solvents (for example, alcohol solvent, glycol solvent or other non-toxic solvents), contains sufficient amount of pigments, has low concentration with good pigment dispersion and storage stability, and shows good writing or recording ability with improved color-development.

  本发明提供了一种用于制备颜料墨水的固体颜料组合物的工艺，包括以下步骤：(a) 将聚乙烯醇溶解在水中，并将颜料分散在所得溶液中；(b) 在所得颜料分散液中加入醛衍生物，并使聚乙烯醇与醛衍生物反应制备聚乙烯醇缩醛；(c) 干燥缩醛颜料分散液。该工艺制得的颜料墨水采用水溶性溶剂（如醇溶剂、乙二醇溶剂或其他无毒溶剂），含有足量颜料，浓度低，颜料分散性和储存稳定性好，书写或记录能力强，显色性好。

  (EN) A substantially water-free, non-dusting and flowable composition comprising an organic peroxide, a hydrocarbyl phthalate, and at least one phlegmatization agent is provided wherein the phlegmatization agent is selected from the group consisting of a polyester and a glycol-based aliphatic carboxylic acid ester, and mixtures thereof. The composition is prepared by: (1) substantially dissolving the hydrocarbyl phthalate and phlegmatization agent in a solvent to form a plasticizer mixture; (2) substantially dissolving the organic peroxide in the plasticizer mixture to form an organic peroxide-plasticizer mixture; (3) cooling the organic peroxide-plasticizer mixture whereby a crystallized composition is formed; and (4) recovering the crystallized composition.(FR) Une composition sensiblement non aqueuse, ne formant pas de poussière et coulante comprend un peroxyde organique, un hydrocarbyle phthalate et au moins un agent de flegmatisation choisi dans le groupe comprenant un polyester et un ester d'acide carboxylique aliphatique à base de glycol, et leurs mélanges. La composition est préparée par (1) dissolution de l'hydrocarbyle phthalate et de l'agent de flegmatisation dans un solvant afin d'obtenir un mélange plastifiant; (2) dissolution du peroxyde organique dans le mélange plastifiant afin d'obtenir un mélange plastifiant-peroxyde organique; (3) refroidissement du mélange plastifiant-peroxyde organique afin d'obtenir une composition cristallisée; et (4) récupération de la composition cristallisée.
