Title:
AQUEOUS FLEXOGRAPHIC PRINTING INK COMPOSITION FOR SURFACE PRINTING
Document Type and Number:
Japanese Patent JP2018076431
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an aqueous flexographic printing ink composition for surface printing excellent in temporal stability at the time of storage, printability and coated film physical properties of a surface-printed printed matter, and to provide an aqueous flexographic printed matter for surface printing obtained by printing using the same.SOLUTION: An aqueous flexographic printing ink composition for surface printing contains (a) an acid group-containing resin emulsion partially or wholly neutralized with a volatile basic compound, (b) a hydrazine-based compound having at least two or more hydrazine residues in the molecule, (c) 0.1-1 equivalent of an aqueous polycarbodiimide compound with respect to 1 equivalent of the acid group of the acid group-containing resin emulsion, (d) a pigment, (e) a surfactant and (f) an aqueous medium.SELECTED DRAWING: None
