    • An ink for inkjet recording containing a vehicle, coloring agents dispersed therein, and a dispersing agent for the coloring agents as required, is provided. The vehicle contains at least a first solvent component and a second solvent component. The first solvent component has the lowest boiling point among the components in the ink, and has a higher viscosity than the ink. The second solvent component has a higher boiling point than the first one. The boiling point of the first solvent component is preferably 280 degree C. or below, and the content thereof is preferably 10 to 80% by weight based on the total weight of the ink. Even when the ink is printed on non-coated papers, the vehicle penetrates little in the thickness direction and bleeds little in the horizontal direction. Clogging in the nozzles can be prevented effectively using the ink even when it has been left in an open atmosphere for a long time.
    • 提供了含有载体的喷墨记录用油墨,分散有着色剂的油墨,以及着色剂的分散剂。 载体包含至少第一溶剂组分和第二溶剂组分。 第一溶剂组分在油墨中的组分中具有最低的沸点,并且具有比油墨更高的粘度。 第二溶剂组分的沸点高于第一溶剂组分。 第一溶剂成分的沸点优选为280℃以下,相对于油墨的总重量,其含量优选为10〜80重量%。 即使将油墨印刷在非涂布纸上时,车辆在厚度方向上几乎不渗透,并且在水平方向上几乎不渗出。 即使长时间处于开放气氛中,也可以有效地防止喷嘴中的堵塞。
