| 摘要 |
<p>The invention provides a curable composition which suppresses precipitation in a low-temperature environment and can form an image with excellent erasibility. The curable composition comprises water, a water-soluable solvenet, a polymeric compound, a 1-[4-(2-hydroxyethoxy)-phenyl]-2-hydroxyl-2-hydroxyl-2-methyl-1-propane-1-ketone as a polymerization initiator and a 2-hydroxyl-2-methyl-1-phenyl-propane-1-ketone as a polymerization initiator. The total content of the polymerization initiator Ia and the polymerization initiator Ib is 0.8-10.0% by mass relative to the total content of the curable composition. The content ratio between the polymerization initiator Ib and the polymerization initiator Ia is 0.2-1.5 times in mass criteria.</p> |
