NOVELTY - An electroconductive material has a conductive layer containing metal nanowire having average short-axis length of 50 nm or less and average long-axis length of 5 mu m or more. The conductor layer contains pyridimine-type compound (I) and tetrazole-type compound (II). The metal nanowire comprises 1 mol of silver and 1x 10-4 1x 10-2 mol of metal(s) chosen from nickel, bismuth, tin, beryllium, chromium and rhodium.    USE - Electroconductive material is used for touch panel (claimed) e.g. surface-type electrostatic capacitive-type touch panel, projection-type electrostatic capacitive-type touch panel, resistance film-type film touch panel. Uses include but are not limited to antistatic for display, electromagnetic wave shield, electrode for organic electroluminescent display, electrode for inorganic electroluminescent display, electronic paper, electrode for flexible display, antistatic for flexible display and solar cell.    ADVANTAGE - The electroconductive material has reduced haze and reflectance and reflective viewing angle dependence, and excellent visibility.    DETAILED DESCRIPTION - An electroconductive material has a conductive layer containing metal nanowire having average short-axis length of 50 nm or less and average long-axis length of 5 mu m or more. The conductor layer contains pyridimine-type compound of formula (I) and tetrazole-type compound of formula (II). The metal nanowire comprises 1 mol of silver and 1x 10-4 1x 10-2 mol of metal(s) chosen from nickel, bismuth, tin, beryllium, chromium and rhodium.    R1-R4=alkyl, aryl, amino (all optionally substituted), H, hydroxy, alkoxy, alkylthio, carbamoyl, halo, cyano, carboxy, alkoxy, carbonyl, or heterocyclic residue, in which at least one of R1 and R3 is hydroxy;    R1+R2 or R2+R3=5 or 6 membered ring;    R5=organic residue optionally substituted by 1-4C alkyl, -SO3M, -COOM, -OH or -NHR6;    M=H, alkali-metal atom, quaternary-ammonium group or quaternary phosphonium group;    R6=H, 1-6C alkyl, -COR7, -COOR7 or -SO2R7;and    R7=H, alkyl or aryl.    INDEPENDENT CLAIMS are included for the following:    (1) manufacture of electroconductive material, which involves coating the conductive layer composition containing metal nanowire on base material, and providing liquid containing pyridimine-type compound (I) and tetrazole-type compound (II) conductive layer; and    (2) touch panel, which has support film and sensor electrode array (a) and sensor electrode array (b) which are formed on support film. The distance of sensor electrode array (a) and sensor electrode array (b) is 50 mu m or less. The sensor electrode array (a) and sensor electrode array (b) are formed using electroconductive material.
