An anticorrosive compsn. for a steel comprises (a) (C3-10) org. salt of dicyclohexylethanolamine 30-45 wt.% i.e. dicyclohexylethanolamine benzoate (or butylate), (b) (C3-10) org. salt. of diisopropylethanolamine 30-45 wt.% i.e. diisopropylethanolamine butylate (or decanoate), (c) urea 5-15 wt.% as a reducing cpd., and (d) NaNO2 25-15 wt.%. The compsn. of 30-70 wt.% is dissolved in water of 30-70 wt.%, doped onto a craft paper by 20-30 g/m2 and air blasting (60-90 deg. C) to give an anticorrosive paper.
