Abstract

PURPOSE: To prepare a temperature indicating paint having high stability and excellent resistance to peeling and thermal cycles, and useful as a temperature indicator of an oven, etc., by compounding a polyimide resin as a film-forming material or binder, with a powdery pigment which turns its color with temperature.
CONSTITUTION: A paint composition having desirable applicability and color tone is obtained by mixing (A) 100 parts by weight of a temperature-indicating pigment powder such as AgI, (B) (pref. 5W20 parts of) a polyimide resin prepared by reacting an aromatic acid anhydride such as pyromellitic anhydride with an aromatic polyamine such as diaminodiphenylmethane, and (C) (pref. 100W300 parts of) a polar solvent such as dimethyl acetamide and dimethylformamide.
