of oleic acidamide derivatives were synthesized based on our previous and continuing endeavors towards stimulation of the 20S core particle of the proteasome (20S CP) with the goal of increasing the protein degradation rate via the ubiquitin-independent pathway. The designed compounds were tested in a variety of biochemical and cell-based assays to assess their ability to increase the rate of hydrolysis
Disclosed is a thermochromic microencapsulated pigment which comprises as four essential components (a) an electron-donating chromatic organic compound, (b) an electron-accepting compound, (c) a reaction medium determining the temperatures at which the color reactions of component (a) with component (b) take place, and (d) a color change temperature regulator, the color change temperature regulator (d) comprising one or more compounds selected from the group consisting of esters, alcohols, ketones, acid amides, hydrocarbons, and fatty acids and having a melting point Y (°C) satisfying the relationship (X+30)°C≤Y≤200°C, wherein X (°C) is the melting point of component (c), and the four essential components being microencapsulated.

[Problems]
The present invention provides a highly marketable reversibly color changeable composition which provides a vivid yellow to orange color during color development, turns colorless during decoloration, and improves light resistance and a reversibly thermochromic microcapsule pigment encapsulating the same.
[Solution]
Disclosed are a reversibly thermochromic composition including: (a) a specific pyridine derivative as an electron-donating color-developing organic compound; (b) an electron-accepting compound; and (c) a reaction medium which reversibly induces an electron transfer reaction between the component (a) and the component (b) in a specific temperature range, and a reversibly thermochromic microcapsule pigment encapsulating the same.
