Title:
METHOD FOR PRODUCING MAGNETIC PARTICLE-CONTAINING COMPOSITION, MAGNETIC PARTICLE-CONTAINING COMPOSITION, MAGNETIC PARTICLE-CONTAINING CURED PRODUCT, MAGNETIC PARTICLE-INTRODUCED SUBSTRATE, AND ELECTRONIC MATERIAL
Document Type and Number:
WIPO Patent Application WO/2023/054565
Kind Code:
A1
Abstract:
The present invention addresses a first problem of providing a method for producing a magnetic particle-containing composition which exhibits excellent storage stability and has a fluidity suitable for coating even if a certain period of time has passed after the composition was stirred. In addition, the present invention addresses a second problem of providing a magnetic particle-containing composition which exhibits excellent storage stability and has a fluidity suitable for coating even if a certain period of time has passed after the composition was stirred. In addition, the present invention addresses a third problem of providing a magnetic particle-containing cured product, a magnetic particle-introduced substrate, and an electronic material. This method for producing a magnetic particle-containing composition includes a step for cooling a precursor composition, which contains magnetic particles, a dispersing agent, and a solvent and/or a liquid reactive monomer, to a temperature of 5°C or lower. The dispersing agent has an amine-based adsorptive group and a crystalline polymer chain.
