Abstract
Provided is a pressure measuring material having a substrate and a pressure-sensitive layer, wherein the pressure-sensitive layer contains a polymer matrix containing a polymer compound having a molecular weight of 1,000 or more, and microcapsules encapsulating an electron-donating dye precursor and a solvent, and an electron-accepting compound. Also provided is a method for manufacturing the pressure measuring material.
