A UV-curable indium oxide type transparent electroconductive film forming coating liquid (P1) contains: (A) indium salt of fatty acid having formula In(OCOR)3 (where R = 1-8C opt. branched alkyl), (B) tin salt of fatty acid having formula Sn(OCOR')2 (where R' = a 1-8C opt. branched alkyl), corresp. to a mol concn. of 0.01-0.3 times the mol concn. of (A), (C) ethanolamine corresp. to a mol concn. of 1-8 times the total mol concn. of (A) and (B), and opt. (D) acetylacetone corresp. to a mol concn. of less than or equal to 4 times the total mol concn. of (A) and (B).    Also claimed is production of (P1) comprising: (1) the first mixing process, in which (A) and (B) corresp. to a mol concn. of 0.01-0.3 times the mol concn. of (A) is mixed in the presence of organic solvent; and then (2) the second mixing process, in which the mixt. of (A) and (B) prepd. in (1) is mixed with (C) corresp. to a mol concn. of 1-8 times the total mol concn. of (A) and (B) and opt. (D) corresp. to a mol concn. l to 4 times the total mol concn. of (A) and (B).    Also claimed is a glass plate (P2) that is coated with (P1) and has baked patterned transparent electroconductive film on the surface obtd. by (1) coating (P1) on a glass substrate and drying and then by (2) placing a photomask on top of the dry (P1) film and irradiating UV light, (3) forming a patterned transparent electroconductive film by developing, and (4) baking at a temp. higher than or equal to 300C.    USE -   (P1) is suitable for forming transparent electroconductive films on surfaces of glass and ceramic substrates, partic. mfg. (P2). (P2) is suitable as a transparent electrode for various displays like liquid crystal displays, fluorescent display tubes and plasma displays, solar batteries, and touch panels, antistatic films, and antifreezing heater and heat radiation reflection films for automobile and aeroplane windows.    ADVANTAGE -   Coating films formed from (P1) transmit visible light and show excellent electroconductivity. Additionally, (P1) emits neither strong acid nor corrosive gas in film formation.
