INK FOR INKJET PRINTER AND PREPARATION METHOD THEREOF

摘要

PURPOSE: An ink for an inkjet printer is provided to use a copper ion to prevent the nozzle from being clogged and to reduce production cost without requiring a separate dispersant. CONSTITUTION: An ink for an inkjet printer comprises a copper ion. The copper ion includes a complexing agent. The complexing agent is ammonia solution(NH4OH). A manufacturing method of the inkjet printer comprises: a step of manufacturing an electrolyte solution by a carboxyl acid solution and the ammonia solution; a step of forming a copper ion by electrically decomposing the electrolyte solution. The manufacturing method additionally comprises a step of forming a copper ion after electrolysis.
