Patent ID: 8668792

Claim:
A method for producing a magnetic sheet comprising: applying a magnetic sheet composition onto a substrate; drying the magnetic sheet composition applied onto the substrate; thermosetting the dried magnetic sheet composition, wherein the magnetic sheet composition comprises: a binder; magnetic powder; and a curing agent, wherein the binder contains a thermosettinq organic resin, and the curing agent contains a sulfonium borate complex expressed by General Formula 1: where R 1 is an o-methyl benzyl group or a (1-naphthyl)methyl group, R 2 is a methyl group, a ethyl group, a propyl group, or a butyl group, X is a halogen atom, and n is an integer of 0 to 3; and stacking a convex-concave forming layer and a pattern transferring layer on a surface of a magnetic layer, which is formed by thermosetting the magnetic sheet composition, in this order from the side of the magnetic layer so as to form a stacked body; and hot-pressing the stacked body so as to transfer a surface configuration of the pattern transferring layer to surfaces of the convex-concave forming layer and the magnetic layer, as well as bonding the convex-concave forming layer and the magnetic layer together.
