  • PHOTOCURABLE COMPOSITION, INKJET INK COMPOSITION, ACTIVE ENERGY RAY-CURABLE INK COMPOSITION, CURED PRODUCT, AND ELECTRONIC COMPONENT
    Publication number: 20230151237
    Abstract: A photocurable composition is capable of forming a cured product that has good reliability in a high-temperature constant-humidity environment, especially good ion migration resistance in a temperature range of 100° C. or higher. The photocurable composition (Z) is obtained by adding an ion scavenger (Y) to a composition (X) containing a monofunctional acrylic monomer (A) and a multifunctional acrylic monomer (B), wherein the content of the monofunctional acrylic monomer (A) relative to 100 wt% of the composition (X) is from 40 wt% to 80 wt%, and the content of the multifunctional acrylic monomer (B) relative to 100 wt% of the composition (X) is from 10 wt% to 50 wt%. An inkjet ink composition contains the photocurable composition (Z); a cured product; and an electronic component.
