Research on Formula of Cyan UV Inkjet Ink

摘要

UV spectrophotometer was used to measure UV transmittance spectrum of pigment and photo-initiators to identify the light transmitting window of a pigment and photo-initiators' absorption peak, then later the types of photo-initiators was determined. In order to determine the optimal assignment of monomers, dispersing agent, defoaming agent and dispersing resin, the uniform design method was supplied to achieve the smallest particle diameter within the range of D95. After the excellent configuration of based ink, the orthogonal design method was used to determine the proportion of based ink, photo-initiators, film-forming resin, additives by regarding viscosity, surface tension, curing speed, and color fastness as indicators.
