INKJET RECORDING METHOD, RADIATION-CURABLE BLACK INK COMPOSITION AND RADIATION-CURABLE YELLOW INK COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a black/yellow radiation-curable ink composition showing excellent flexibility in a recorded image and capable of suppressing development of aggregation spots (uneven glossiness) on a surface of the image.SOLUTION: A radiation-curable black ink composition of the present invention comprises (A) a phenoxyethyl acrylate by 20 mass% or more and 55 mass% or less in a reaction component, (B) a polyfunctional acrylate by 20 mass% or more and 50 mass% or less in the reaction component, and (F1) a black pigment. A radiation-curable yellow ink composition of the present invention comprises (A) a phenoxyethyl acrylate by 20 mass% or more and 55 mass% or less in a reaction component, (B) a polyfunctional acrylate by 10 mass% or more and 50 mass% or less in the reaction component, and (F2) an yellow pigment.SELECTED DRAWING: None
