Abstract: Provided are a waterborne polyurethane (WPU) and a preparation method thereof, and a waterborne scratch-off ink and a preparation method thereof. A chain end group or side group of the WPU contains a longer alkyl chain. When the WPU is used in the preparation of the waterborne scratch-off ink, microphase separation may occur during the film-forming process owing to a hydrophobic/hydrophilic interaction between the non-polar long-chain alkyl and polar groups in WPU molecular, resulting in an incomplete film structure, which is beneficial to make the ink be scratched off.
