Inorganic powder-containing resin composition, film-forming material layer, transfer sheet, method for producing substrate with dielectric layer, and substrate with dielectric layer

摘要

The invention provides an inorganic powder-containing resin composition capable of forming a dielectric layer having high light transmittance and excellent in surface smoothness. The invention also provides a film-forming material layer, a transfer sheet and a dielectric layer, which comprise the composition, a method of producing a substrate having a dielectric layer formed thereon, and a substrate having a dielectric layer formed thereon. The inorganic powder-containing resin composition comprises inorganic powder, a binder resin, and a phosphorus compound represented by formula (1): wherein R¹, R² and R³ independently represent H, an alkyl group, an alkylaryl group, NH₄⁺ (ammonium) or -(CH₂CH₂O)_n-R⁴, wherein n is 1 to 15, and R⁴ represents H, an alkyl group, an alkylaryl group or a (meth)acryloyl group.
