Document Type and Number:
WIPO Patent Application WO/2021/161789
Kind Code:
A1
Abstract:
The present invention provides a pressure-measuring sheet set, pressure-measuring sheet, method for manufacturing a pressure-measuring sheet set, method for manufacturing a pressure-measuring sheet, dispersion, dispersion set, and microcapsules of superior storage stability. A pressure-measuring sheet set according to the present invention comprises a first sheet having a first layer including microcapsules containing a color coupler, and a second sheet having a second layer containing a developer. The color coupler is selected from a group consisting of compounds represented by general formula (1) and compounds having an indole structure. The microcapsules also contain a compound having a benzotriazole structure and an aromatic solvent.
