  • Device for discharging liquid, method for discharging liquid, curable composition, curable ink, cured product, and storing container
    Patent number: 10851255
    Abstract: A device for discharging liquid is provided. The device includes a liquid discharge head including a curable composition, individual liquid chambers, and a nozzle. The curable composition comprises polymerizable compounds including a bifunctional or higher multifunctional compound accounting for 25% by mass to 45% by mass of an entire amount of the polymerizable compounds and a particle having an average primary particle diameter of 20 nm to 100 nm. The individual liquid chambers have circulation channels in which the curable composition circulates. The nozzle is communicated with the individual liquid chambers, and configured to discharges droplets.
