The present invention relates to a color developing film and a pressure test film and a method of manufacturing the same. The color developing film includes a substrate, and an undercoat layer, an uneven structure layer and a color developing layer sequentially stacked on the substrate, and the color developing layer includes a microcapsule containing an electron-donating colorless dye precursor. By using a specific formula, the pressure test film can have high sensitivity and high resolution and meet the requirements for use in a low temperature environment. |
