Abstract
An ink set for forming a multilayer of the present invention includes a group of coloring ink compositions which include a yellow, a magenta, a cyan and a black ink composition, and a clear ink composition, wherein each of the coloring ink compositions contain a (component A) radical polymerizable compound, a (component B) radical polymerization initiator and a (component D) coloring agent, and the component A contains a (component A-1) N-vinyl compound and a (component A-2) specific ethylenic unsaturated compound (CTFA), the clear ink composition contains a (component A) radical polymerizable compound, a (component B) acylphosphine oxide-based photoinitiator and a (component C) surfactant, and the relation of 0.1≦(Y/X)<1 is satisfied when the content of the radical polymerization initiator in the clear ink composition is X, the content of the radical polymerization initiator in the magenta ink composition is Y.
