摘要： The present invention relates to to a process for preparation of silver coralex compound and the compositions of silver ink containing the same. The present invention includes a) preparing silver complex compound with special structure by reacting silver compound with at least one or two mixtures selected from ammonium carbamate compound, ammonium carbonate compound or ammonium bicarbonate compound and b) preparing silver nano particles by reacting the silver complex compound with reducer or reducing or pyrolyzing the silver complex compound by applying heat thereto. The preparaing method according to the present invention can prepare the silver nano practicle with various shapes through a simple preparation process, improve the selectivity of the size of the silver comlex compound, fire the silver comlex compound even when it is fired at a low temperature of 150 °Cor less during a shor time, provide the ink compositions capable of forming the coating or the fine pattern showing the high conductivity while facilitating the thickness control of the coating, and provide the ink compositions capable of being applied to the reflective film material, the electromagnetic wave shield, and the antimicrobial agent, etc.
