Summary: | An ink composition containing a micro-encapsulated UV absorber. The ink composition includes a micro-encapsulated UV absorber, a dispersant, an emulsifer, at least one colorant, and a medium. The present invention adds a micro-encapsulated UV absorber to inkjet ink or screen printing ink. The micro-encapsulated UV absorber is suitable for either a water-based system or solvent-based system. The micro-encapsulated UV absorber increases the light-fastness and maintains longer-term light resistance because the UV absorber is gradually released from the microcapsule. The ink composition of the present invention provides excellent printing quality when used in inkjet or screen printing. |
