[Object]
To provide an active energy ray-curable ink composition for offset printing capable of achieving superior gloss of printed matter.
[Solution]
An ink composition comprises a compound having at least one ethylenically unsaturated bonds and a photopolymerization initiator, wherein a group of materials having no ethylenically unsaturated bond, having a specified SP value, and exhibiting a liquid state at room temperature is added to the ink composition up to the upper limit depending on the SP value. Examples of such a group of materials include castor oil, hardened castor oil, polymerized castor oil, coconut oil, palm kernel oil, epoxidized fats and oils, alkylphenols having C15-C18 alkyl groups, cashew nut shell liquid, polymers of cashew nut shell, and modified derivatives of cashew nut shell liquid.
目的
提供一种用于胶版印刷的活性能量射线固化油墨组合物,该组合物能够使印刷品获得极佳的光泽度。
[解决方案]
一种油墨组合物由至少有一个乙烯不饱和键的化合物和一种光聚合引发剂组成,其中一组没有乙烯不饱和键、具有特定 SP 值、在室温下呈液态的材料被添加到油墨组合物中,添加量根据 SP 值的上限而定。这类材料的例子包括蓖麻油、硬化蓖麻油、聚合蓖麻油、椰子油、棕榈仁油、环氧化油脂、具有 C15-C18 烷基的烷基酚、腰果壳液、腰果壳聚合物和腰果壳液的改性衍生物。
