| 摘要 |
<p>The present invention relates to a print-ink stacked body obtained by stacking, upon a transparent plastic film (1), a white ink film layer (2) formed using print ink including a polyurethane resin (A) and a white inorganic pigment, and a coloured ink film layer (3) formed using print ink including a polyamide resin (B) and an organic pigment, in that order, said print-ink stacked body wherein the polyurethane resin (A) is obtained by causing a reaction between an organic diamine and a urethane prepolymer having an isocyanate group at a terminal thereof, said urethane prepolymer being obtained by causing a reaction between a polymer polyol and polyisocyanate. According to the present invention, an ink stacking method can be used to produce an ink stacked body exhibiting, among other necessary properties, excellent white/colour-layer gloss, while reducing the usage amount of residual solvents.</p> |
