METHOD FOR PREPARING HIGH-SENSITIVITY HEAT-SENSITIVE REVERSIBLE COLOR-CHANGING MICROCAPSULE

Title:

METHOD FOR PREPARING HIGH-SENSITIVITY HEAT-SENSITIVE REVERSIBLE COLOR-CHANGING MICROCAPSULE

Document Type and Number:

WIPO Patent Application WO/2022/257684

Kind Code:

A1

Abstract:

A fluorane dye shown in the following formula, a method for preparing a two-component heat-sensitive reversible color-changing material compound using same and the compound prepared thereby, and a method for preparing heat-sensitive reversible color-changing microcapsules using the compound and the microcapsule prepared thereby. The fluorane dye can achieve the color-changing property without a color developer, and the microcapsule has good color performance and color-changing response performance, so that the color hysteresis phenomenon of traditional three-component thermochromic capsules can be effectively mitigated.
