EXAMPLE - Silver nanowire dispersion was formed as follows. Silver nitrate powder (0.51 g) was dissolved in pure water (50 ml). Subsequently, 1N aqueous ammonia was added to the resultant solution until the solution was transparent. Then, pure water was added to the transparent solution so that the total amount was 100 ml, to obtain additive liquid A. Glucose powder (0.5 g) was dissolved in pure water (140 ml) to prepare additive liquid G. Then, hexadecyl-trimethylammonium bromide (HTAB) powder (0.5 g) was dissolved in pure water (27.5 ml) to prepare additive liquid H. Then, a silver nanowire aqueous dispersion was prepared as follows. Pure water (410 ml) was added to a three-necked flask. With stirring at 20 degrees C, additive liquid H (82.5 ml) and additive liquid G (206 ml) were added to the flask using a funnel (first step). Additive liquid A (206 ml) was then added to the resultant liquid at flow rate of 2 ml/minute under stirring at 800 rpm (second step). 10 Minutes after, additive liquid H (82.5 ml) was added to it. The resultant mixture was increased to internal temperature of 75 degrees C at a rate of 3 degrees C/minute, followed by heating for 5 hours under stirring at 200 rpm. The obtained aqueous dispersion was cooled. Separately, ultrafiltration apparatus was assembled. The silver nanowire dispersion (aqueous solution) was ultrafiltrated. At the time when, amount of the filtrate reached 50 ml, distilled water (950 ml) was added to stainless steel cup for washing. The washing was repeated until conductivity reached less than or equal to 50 mu Second/cm, followed by concentrating, whereby a silver nanoparticle aqueous dispersion was obtained. The obtained silver nanoparticles were found to have wire shape with average minor axis length of 18 nm and average major axis length of 38 mu m. The silver nanowires had variation coefficient of diameters, appropriate wire yield, and degree of sharpness of 22.4%, 78.7% and 44.1, respectively. Subsequently, K-30 (RTM: polyvinylpyrrolidone) and propylene glycol monomethyl ether (PGME) were added to silver nanoparticle aqueous dispersion, followed by centrifugation. The supernatant was removed through decantation and then PGME was added to precipitate for redispersion. This centrifugation/decantation/redispersion procedure was repeated 3 times to obtain silver nanowire PGME dispersion. The silver content of dispersion was 2 mass%. A polymer solution (A1) was formed as follows. Methanol (167 g), ethyl acetate (333 g), benzyl methacrylate (130 g), KAYARAD TC-110S (RTM: esters of methacrylic acid with adducts of tetrahydrofuryl alcohol with epsilon -caprolactone) (30 g), 2-hydroxyethyl methacrylate (20 g), methacrylic acid (20 g), azobisisobutyronitrile (1 g) and thioglycolic acid (3 g) were mixed and stirred, followed by polymerizing at 65 degrees C for 6 hours. The liquid obtained after the polymerization was added to cyclohexane (3000 g) for precipitating formed polymer. After supernatant had been removed through decantation, precipitate (polymer) was dried under vacuum at 40 degrees C for 20 hours, to obtain polymer (138 g). The obtained polymer was found to be random copolymer in which amount of benzyl methacrylate was (56 mol%), amount of KAYARAD TC-110S was (8 mol%), amount of 2-hydroxyethyl methacrylate was (13 mol%), amount of methacrylic acid was (23 mol%), and weight average molecular weight (converted to polyethylene oxide) of 7000. The obtained polymer (0.46 g), M-400 (RTM: acrylic resin) (0.46 g), 4,4'-bis(diethylamino)benzophenone (0.046 g), 25% toluene solution of 3,4,4'-tri(tert-butylperoxycarbonyl)benzophenone (0.182 g) and BYK-300 (RTM: surfactant) (0.002 g) were added to propylene glycol monomethyl ether acetate (3.3 g), followed by mixing and stirring, to synthesize polymer solution (A1). A polymer solution (A5) was formed as follows. Methanol (142 g), ethyl acetate (283 g), benzyl methacrylate (130 g), 2-hydroxyethyl methacrylate (20 g), methacrylic acid (20 g), azobisisobutyronitrile (0.85 g) and thioglycolic acid (2.55 g) were mixed and stirred, followed by polymerizing at 65 degrees C for 6 hours. The liquid obtained after polymerization was added to cyclohexane (3000 g) for precipitating formed polymer. After supernatant had been removed through decantation, precipitate (polymer) was dried under vacuum at 40 degrees C for 20 hours, to obtain polymer (115 g). The obtained polymer was found to be random copolymer in which amount of benzyl methacrylate was (58 mol%), amount of 2-hydroxyethyl methacrylate was (17 mol%), amount of methacrylic acid was (25 mol%), and had weight average molecular weight (converted to polyethylene oxide) of 7200. Then, the obtained polymer (0.46 g), M-400 (0.46 g), 4,4'-bis(diethylamino)benzophenone (0.046 g), 25% toluene solution of 3,4,4'-tri(tert-butylperoxycarbonyl)benzophenone (0.182 g) and BYK-300 (0.002 g) were added to propylene glycol monomethyl ether acetate (3.3 g), followed by mixing and stirring, to synthesize polymer solution (A5). A test photosensitive resin composition was formed as follows. Under stirring, the silver nanowire PGME dispersion (20 g) was gently added dropwise to polymer solution (A1). A comparative photosensitive resin composition was formed similarly as the test composition, except that polymer solution (A1) was changed to polymer solution (A5). Further, patterned transparent conductive film was formed as follows. A glass substrate was coated through slit coating with the test/comparative photosensitive composition, followed by drying for 2 minutes on hot plate at 90 degrees C (pre-baking). The substrate was exposed through a mask to i beams (365 nm) from high-pressure mercury lamp at 100 mJ/cm2 (dose = 20 mW/cm2). The thus-exposed glass substrate was subjected to shower development for 30 seconds using developer which had been prepared by dissolving in pure water (5000 g), sodium hydrogencarbonate (5 g) and sodium carbonate (2.5 g). The showering pressure was set to 0.04 MPa, and the time required that a stripe pattern appeared was 15 seconds. The substrate was rinsed through showering of pure water and then postbaked at 200 degrees C for 10 minutes, to obtain the patterned transparent conductive film. The patterned transparent conductive films formed from the photosensitive compositions were then evaluated for various properties, and the results for test/comparative compositions were as follows: conductivity ( Omega /square) = 11/130; resolution for forming pattered transparent conductive film = good/not good (NG); transparency (%) = 93/92; solvent resistance = good/good; alkali resistance = good/good; heat resistance (%) = 92/91; and adhesion = good/NG.
