Process of curing a polymerizable composition containing a magnetized powered ferromagnetic material with radioactive rays
First Claim
1. A process of curing a composition comprising the step of mixing at least one polymerizable ethylenically unsaturated composition selected from the group consisting of polymerizable resins having ethylenically unsaturated groups therein and ethylenically compounds and a filler comprising a magnetized powdery ferromagnetic substance in an amount of 1.5 to 998 parts by weight based on 100 parts by weight of the at least one polymerizable composition and then curing the mixture with radioactive rays selected from the group consisting of X-rays, β
- rays, γ
rays, X rays and electron beams in an amount of from 2.5 to 10 Mrads.

Abstract
A process for curing a resin composition for the manufacture of plastic thin films by radiation curing with radioactive rays comprising mixing a radical-polymerizable resin with a filler, characterized in that at least a part of the filler is composed of a powdery ferromagnetic substance and in that said powdery ferromagnetic substance is incorporated in an amount of 1.5 to 998 parts by weight based on 100 parts by weight of the radical-polymerizable resin.
