An active for use in the treatment or inhibition of an inflammatory disease associated with over-activation of Toll-like Receptor 4 (TLR4), Toll-like Receptor 2 (TLR2) and Myeloid differentiating protein 88 (Myd88) adaptor-like protein (Mal) while maintaining a subject's ability to respond normally to a pathogen, in which the active is an oleamide or a derivative thereof.
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.
Provided is a non-fluorinated block copolymer comprising at least one block segment (A), wherein the block segment (A) comprises a repeating unit formed from one or more types of acrylic monomer having a long-chain hydrocarbon group containing 7-40 carbon atoms, and the block copolymer imparts superior liquid repellency to a base material such as fibers. The non-fluorinated block copolymer preferably contains a segment (B) constituted by at least one of: (B1) a block segment comprising a repeating unit, different from that of segment (A), that is formed from an acrylic monomer having a long-chain hydrocarbon group comprising 7-40 carbon atoms; (B2) a block segment comprising a repeating unit formed from an acrylic monomer not having a long-chain hydrocarbon group; and (B3) a random segment formed from at least two types of acrylic monomers.
