Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a lubricant for warm/hot plastic working, having a low coefficient of friction even in a resistant processing, exhibiting excellent anti- seizing properties and not deteriorating the working environment. SOLUTION: This lubricant comprises (a) an alkali metal carbonate and/or hydrogencarbonate and (b) an aromatic carboxylate. The component (a) can be sodium carbonate, potassium carbonate, sodium hydrogencarbonate, potassium hydrogencarbonate, etc., and the component (b) can be sodium (potassium) phthalate, sodium (potassium) hydrogenphthalate, sodium (potassium) iso phthalate, sodium (potassium) terephthalate, sodium (potassium) trimellitate, sodium (potassium) pyromellitate or the like. The content of the component (a) can be 0.5-25 wt.% and that of the component (b) can be 0.5-25 wt.%.
