NOVELTY - Solvent-free UV inkjet comprises 20-80 pts. wt. monofunctional monomer, 20-60 pts. wt. bifunctional monomer, 1-30 pts. wt. acrylic oligomer, 1-15 pts. wt. nano-pigment, 1-20 pts. wt. photoinitiator, 0.1-1 pts. wt. dispersant, 0.1-1 pts. wt. leveling agent, 0.1-1 pts. wt. defoamer and 1-25 pts. wt. adjuvant. USE - Used as solvent-free UV inkjet. ADVANTAGE - The solvent-free UV inkjet: has low viscosity, good fluidity and high stability; exhibits stable printing quality during long-term continuous printing; has good adhesion; is environmentally friendly, low production costs, and suitable for high-speed, batch printing. DETAILED DESCRIPTION - AN INDEPENDENT CLAIM is also included for preparing a solvent-free UV inkjet comprising (1) providing above raw materials, (2) adding auxiliary agent, dispersant, and nano-pigment to the monofunctional monomer, adjusting the rotating speed and stirring evenly, and using a sand mill to grind to obtain a color paste of the required fineness and (3) adding bifunctional monomers, acrylic oligomers, photoinitiator, leveling agent, defoaming agent to the color paste, stirring, and discharging.
