To obtain a conductive film compsn. which uses ethylene glycol, or the like, as the main solvents, contains an indium compd., a polycarboxylic acid, or the like, and is excellent in light transmittance, abrasion resistance, and adhesion to substrates such as glass and ceramics.
This compsn. contains (A)(i) 10-40 wt.% ethylene glycol and (ii) 10-40 wt.% terpineol as the main solvents, (B) ethyl alcohol, n-butyl alcohol, and Ethyl Cellosolve as the auxiliary solvents, each in an amt. of 10-50 wt.%, and (C) solid components comprising (i) 1-10 wt.% indium compd., (ii) 0.1-3 wt.% polycarboxylic acid such as oxalic or malonic acid, and (iii) 0.1-3 wt.% tin compds. mainly comprising tin octanoate.
