Document Type and Number:
WIPO Patent Application WO/2019/102855
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an aqueous liquid ink which exhibits fundamental characteristics as an aqueous liquid ink (adhesion to a base material, blocking resistance, a high printing density, and the like), and which also exhibits high water resistance (boil retort properties) and solvent resistance. This aqueous liquid ink includes a colouring agent (A), a binder (B) having acid groups, a basic compound (C), and an aqueous medium (D). The binder (B) having acid groups includes a urethane resin (B1) which is a reaction product of a polyisocyanate (b2), and a polyol (b1) including at least one from among a polyol (b1-1) having acid groups, a polyester polyol (b1-2), and a polycarbonate polyol (b1-3). The content of alicyclic structures in the urethane resin (B1) is at least 1,000 mmol/kg. The basic compound (C) includes at least one from among a basic metal compound (C1) and an organic amine (C2).
