An ink is provided which can prevent the deformation and degradation of resin products by printed items, and is also suitable for inkjet printing. The oil-based inkjet ink contains a colorant and a fatty acid ester-based solvent represented by general formula (1) shown below and having 12 to 23 carbon atoms in one molecule.
(In general formula (1), each of R1 and R2 independently represents an alkyl group, and at least one of the alkyl groups of R1 and R2 is a branched alkyl group having a side chain of at least 4 carbon atoms.).
本发明提供了一种油墨,它可以防止树脂产品因印刷品而变形和降解,同时也适用于喷墨印刷。这种油基喷墨墨水含有着色剂和脂肪酸酯基溶剂,其通式(1)如下所示,一个分子中含有 12 至 23 个碳原子。
(在通式(1)中,R1 和 R2 各自独立地代表一个烷基,R1 和 R2 的烷基中至少有一个是具有至少 4 个碳原子侧链的支链烷基)。
