Abstract:
To provide an actinic-ray-curable ink set for ink-jet recording which is excellent in thick-film curability even when a UV-LED lamp is used as a light source, and has uniform curing sensitivity across different colors. The present invention relates to an actinic-ray-curable ink set for ink-jet recording, characterized in that a cyan ink contains a phthalocyanine pigment, a radical polymerizable compound, and less than 10% by mass of a photopolymerization initiator based on the total amount of the cyan ink, a magenta ink contains a quinacridone-based pigment, a radical polymerizable compound, and less than 5% by mass of a photopolymerization initiator based on the total amount of the magenta ink, a yellow ink contains an azo pigment, a radical polymerizable compound, and less than 10% by mass of a photopolymerization initiator based on the total amount of the yellow ink, and a black ink contains a carbon black, a radical polymerizable compound, and less than 12% by mass of a photopolymerization initiator based on the total amount of the black ink.
