Preparation and Characterisation of Polyurethane Acrylate-Based Titanium Dioxide Pigment for Blue Light-Curable Ink
Herein, a polyurethane acrylate-based TiO<sub>2</sub> (PU-TiO<sub>2</sub>) was fabricated using a two-step method. First, a polyurethane prepolymer was prepared. Second, PU-TiO<sub>2</sub> was prepared using amino-modified TiO<sub>2</sub> (A-TiO<sub...
