PRESSURE MEASURING MATERIAL - A simplified explanation of the abstract
This abstract first appeared for US patent application 18357182 titled 'PRESSURE MEASURING MATERIAL
Simplified Explanation
The patent application describes a pressure measuring material that includes a substrate and a pressure-sensitive layer.
- The pressure-sensitive layer contains a polymer matrix, a dye precursor, a solvent, and an electron-accepting compound.
- The pressure-sensitive layer has two layers: a color development-inducing layer and a color-developing layer.
- The color development-inducing layer contains the electron-accepting compound and the polymer matrix.
- The color-developing layer contains microcapsules that encapsulate the dye precursor and the solvent.
- The thickness of the color-developing layer is equal to or less than half of the thickness of the color development-inducing layer.
Original Abstract Submitted
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. The pressure-sensitive layer has a color development-inducing layer having the electron-accepting compound and the polymer matrix and a color-developing layer having the microcapsules. A thickness of the color-developing layer is equal to or less than ½ of a thickness of the color development-inducing layer.
