Title:
CURABLE COMPOSITION, INK FOR SOLDER RESIST, AND PRINTED CIRCUIT BOARD
Document Type and Number:
WIPO Patent Application WO/2022/059304
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a curable composition from which a cured product having excellent adhesiveness and heat resistance and a low relative dielectric constant is formed; an ink for solder resist; and a printed circuit board using the same. A curable composition according to the present invention contains a (meth)acrylic monomer as a main component and further contains a photopolymerization initiator, a thermosetting compound, and a gelling agent, the curable composition being characterized in that a cured product of said curable composition has a relative dielectric constant of less than 2.90 at 10 GHz.
