Abstract
The present invention relates to a process for preparation of silver nanoparticles and the compositions of silver ink containing the same. The present invention can prepare the silver nanoparticles with various shapes through a simple preparation process, improve the selectivity of the size of the silver nanoparticles, fire the silver nanoparticles even at a low temperature of 150° C. or less during a short time, provide the ink compositions capable of forming the coating or the fine pattern showing the high conductivity, and provide the ink compositions capable of being applied to the reflective film material, the electromagnetic wave shield, and the antimicrobial agent, etc.
