Beschreibung
Zusammenfassung:	The present invention is an active light-curable inkjet ink which contains a gelling agent, an ultraviolet absorbent and a photopolymerizable compound. The molecular weight of the ultraviolet absorbent is from 300 to 1,000 (inclusive); and the content of the ultraviolet absorbent is from 5% by mass to 60% by mass (inclusive) relative to the total mass of the gelling agent. According to the present invention, weather resistance of an ink is able to be sufficiently enhanced even if the ink is an inkjet ink containing a gelling agent and an ultraviolet absorbent, while suppressing decrease in the pinning properties and decrease in the storage stability of the gelling temperature of the ink caused by the ultraviolet absorbent contained in the ink.
