초록 ▼

A new reversible temperature indicating composition for use in temperature indicating instruments is diclosed which is capable of accurate temperature indication in a variety of colors and characterized by a minimum range of hysteresis so that the marking drawn in this composition can decolor at or close the temperature at which its coloring takes place. In addition, the composition can provide a wide variety of hues and can be readily prepared. These and other advantages are provided by the inclusion as a main ingredient of an ester compound having DD

대표청구항 ▼

A reversible temperature-indicating composition consisting essentially of: (A) an electron-donating chromatic organic compound selected from the group consisting of diaryl phthalides, polyaryl carbinols, leuco auramines, acyl auramines, aryl auramines, Rhodamine B lactams, indolines, spiropyrans, and fluorans; (B) a compound selected from the group consisting of phenolic compounds having 6 to 49 carbon atoms, metal salts of the phenolic compounds, aromatic carboxylic acids having 7 to 12 carbon atoms, aliphatic carboxylic acids having 2 to 5 carbon atoms, metal salts of carboxylic acids having 2 to 22 carbon atoms, acidic phosphoric esters having 1 to 44 carbon atoms, metal salts of the acidic phosphoric esters and triazole compounds having 2 to 24 carbon atoms; and (C) an ester compound, said components (A), (B), and (C) being present in a weight ratio in the range of 1:0.1 to 50:1 to 800,and being in a form of homogeneous fused mixture, wherein said component (C) is selected from following compounds having D3°C. or less: a branched alkyl ester and arylalkyl ester of straight-chain saturated aliphatic carboxylic acid and an alkyl ester of aliphatic carboxylic acid having double bond(s), branched alkyl group, hydroxyl group, carbonyl group or halogen atom in the carbon chain. A reversible temperature-indicating composition as claimed in claim 1, wherein the composition comprises the core of microcapsules having a diameter of 30 m
