A microcapsulated pigment contains, as reaction media one or more specific aliphatic acid alcohol esters obtained from monohydric aliphatic alcohols having odd numbers of carbon atoms and aliphatic carboxylic acids, these reaction media in a homogenious compatible state with chromatic components are occluded in microcapsules to obtain characteristics of thermochromism with a hysteresis range (segment HG) from 8°C to 30°C.
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.
A thermally color-developing reversibly thermochromic pigment which shows a uniform color density in the coloring temperature range and also shows an optional ΔH value within a range of from 3 to 40°C of the ΔH value (hysteresis temperature range) in a temperature-color density curve. Thermally color-developing reversibly thermochromic pigments of a three component system having a ΔH value of within a range of from 7 to 40°C in which at least essential three components including (a) an electron-donating chromic organic compound, (b) a specified compound selected from gallic acid esters and (c) a reaction medium selected from alcohols, esters, ketones and hydrocarbons, which reversibly generates color reactions of both of the compounds within a specified temperature range and has a melting point of less than 50°C, are microencapsulated, and of a four component system having a ΔH value of within a range of from 3 to 25°C in which a compound (d) selected from monomer compounds having a melting point of 50°C or more or polymer compounds having a softening point of 70°C or more is added to the three component system.

A micro integrated analysis system includes a testing chip, system main body and heat-insulating section. The chip has a pump connecting section to communicate with micro pumps; a mixing flow path for mixing a specimen and reagent and for reaction processing by heating; and a testing flow path for performing a predetermined test of a mixed solution heated and processed for reaction. The system main body has a holding section to hold the testing chip; micro pumps for injecting a specimen and reagent; a heating section for heating the mixing flow path; and a detection section for performing a test in the testing flow path. The heat-insulating section insulates flow path portions continuing from both an inlet end and outlet end of a heated flow path area of the mixing flow path, from heat of the heating section so as to prevent a rise in temperature.
