    • An ink composition for ink jet printing is provided which gives a cured object excellent in adhesion to metallic plates, resistance to etchants, and alkali removability and can be stably ejected with an ink jet apparatus. The ink jet composition for etching resists has a viscosity at 25° C. of 3-50 mPa s and includes monomers comprising: either a polymerizable phosphoric ester compound represented by general formula (I); a polyfunctional monomer having two or more ethylenic double-bond groups per molecule and having no phosphoric ester group, the content of the ethylenic double-bond groups being 4×10−3 to 8×10−3 mol/g; and a monofunctional monomer having one ethylenic double-bond group per molecule and having neither phosphoric ester group nor carboxy group. In the formula, X represents C1-3 alkylene, Y represents C2-3 alkylene, and R represents hydrogen or methyl.
    • 提供一种用于喷墨印刷的油墨组合物,其提供了对金属板的粘附性优异,耐蚀刻剂和碱可除去性优异的固化物,并且可以用喷墨设备稳定地喷射。 用于抗蚀剂的喷墨组合物在25℃下的粘度为3-50mPa·s,并且包括单体,其包含:由通式(I)表示的可聚合磷酸酯化合物; 每分子具有2个以上的烯属双键基并且不具有磷酸酯基的多官能单体,烯键式双键基团的含量为4×10 -3〜8×10 -3 mol / g; 和每分子具有一个烯属双键基并且既不具有磷酸酯基也不具有羧基的单官能单体。 在该式中,X表示C1-3亚烷基,Y表示C2-3亚烷基,R表示氢或甲基。
