Reversible heat-sensitive composition using the same, coloring and decoloring properties and processes reversible thermosensitive recording material and hydroxyphenyl hydroxyalkyl amide compound,

摘要

Was using it and hydroxyphenyl hydroxyalkyl amide compound, a novel, balance of decoloring temperature stability of the color and erasable, color sensitivity, and color temperature, as well as excellent storage stability against heat in the colored state, reversible provision of coloring and decoloring properties erogenous process heat composition, and reversible thermosensitive recording material. Reversible thermosensitive composition comprising an electron-donating color-forming compound and the electron-accepting compound and hydroxyphenyl hydroxyalkyl amide compound represented by the following general formula (I) and the reversible thermosensitive recording material. The recording material may be coloring or decoloring by controlling the temperature. [Formula 1] (N is an integer of 1 to 3, the hydroxyl group is bonded to a terminal carbon atom other than carbon, A is. Hydroxyalkyl linear group) [Selection] Figure Figure 1
