Title:
COMPOSITION, MAGNETIC PARTICLE-CONTAINING CURED PRODUCT, MAGNETIC PARTICLE-INTRODUCED SUBSTRATE, AND ELECTRONIC MATERIAL
Document Type and Number:
WIPO Patent Application WO/2022/202394
Kind Code:
A1
Abstract:
The first problem addressed by the present invention is to provide a composition with which it is possible to form a cured product that is superior in terms of achieving high permeability and low magnetic loss, that has a superior hole filling capability, and that also has a superior storage stability. In addition, the second problem addressed by the present invention is to provide a magnetic particle-containing cured product formed by employing the above-described composition. Furthermore, the third problem addressed by the present invention is to provide a magnetic particle-introduced substrate and an electronic material, each of which contains the above-described magnetic particle-containing cured product.　The composition according to the present invention contains magnetic particles and an organic solvent, wherein: the magnetic particles contain magnetic particles X in which the sphericity is 100-120; the magnetic particles X contain ferrite particles; among the magnetic particles X, the contained amount of magnetic particles in which the circle equivalent diameters are less than 11 µm is 15-70 mass% with respect to the total mass of the magnetic particles X; and the volume average particle size of the magnetic particles X is 5-50 µm.
