ACTINIC RADIATION-CURABLE INKJET RESIST INK, METHOD FOR FORMING CURED FILM, CURED FILM, PRINTED WIRING BOARD, AND ELECTRONIC DEVICE

WIPO Patent Application WO/2023/233894

A1

The ink according to the present invention is an actinic radiation-curable inkjet resist ink comprising an actinic radiation-polymerizable compound (A), a pigment (B), and a pigment dispersant (C), wherein: the pigment (B) contains a red pigment (B1) having a maximum absorption wavelength from 480 nm to 600 nm and a pigment (B2) having a color different from that of the red pigment (B1); the pigment dispersant (C) has an amine value larger than its acid value; the halogen content in the inkjet resist ink is not more than 900 ppm; and the actinic radiation-curable inkjet resist ink substantially does not contain a black inorganic pigment.
