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.

Claim (Index 4):
The actinic-ray-curable ink set for ink-jet recording according to  claim 2 , wherein\n the cyan ink contains less than 10% by mass, based on the total amount of the cyan ink, of an acylphosphine oxide-based photopolymerization initiator that has a mass ratio of bis(2,4,6-trimethylbenzoyl)-phenylphosphine oxide to 2,4,6-trimethylbenzoyl-diphenyl-phosphine oxide of 0.1 to 0.4, the magenta ink contains less than 5% by mass, based on the total amount of the magenta ink, of an acylphosphine oxide-based photopolymerization initiator that has a mass ratio of bis(2,4,6-trimethylbenzoyl)-phenylphosphine oxide to 2,4,6-trimethylbenzoyl-diphenyl-phosphine oxide of 0.4 to 0.8, the yellow ink contains less than 10% by mass, based on the total amount of the yellow ink, of an acylphosphine oxide-based photopolymerization initiator that has a mass ratio of bis(2,4,6-trimethylbenzoyl)-phenylphosphine oxide to 2,4,6-trimethylbenzoyl-diphenyl-phosphine oxide of 0.1 to 0.4, and the black ink contains less than 10% by mass, based on the total amount of the black ink, of an acylphosphine oxide-based photopolymerization initiator that has a mass ratio of bis(2,4,6-trimethylbenzoyl)-phenylphosphine oxide to 2,4,6-trimethylbenzoyl-diphenyl-phosphine oxide of 0.1 to 0.4.
