AQUEOUS LIQUID INK AND PRINTED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2019/102854
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an aqueous liquid ink which exhibits adhesion to a base material, blocking resistance, redissolution properties, and a high printing density, and which is also capable of achieving high water resistance (boil retort properties). 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 a polyol (b1-1) having acid groups and a polyether polyol (b1-2). The content of alicyclic structures included in the urethane resin (B1) is in the range of 1,000-5,000 mmol/kg inclusive. The basic compound (C) includes a basic metal compound (C1) and an organic amine (C2).
