Abstract
According to the invention, the surface of a substrate possessing an active hydrogen group is contacted with a chemical adsorbent containing a radical generation precursor group or metal ion capturing group within a molecule--also possessing a reactive functional group such as halosilyl or alkoxy silyl at its end--to form a chemical adsorption film by removing the unreacted chemical adsorbent, radicals are then generated and magnetism is expressed on the chemical adsorption film.
