Abstract:
1. A multilayer body having a patternable resist layer comprising a photo-acid generating agent and a resist-protecting film on a substrate, wherein the resist protecting film comprises an antistatic resin and a photo-acid generating agent, wherein said photo-acid generating agent in said resist-protecting film is the same as the photo-acid generating agent in said resist layer, and the content of said photo-acid generating agent in said resist-protecting film is the same as or higher than that of the photo-acid generating agent in said resist layer, wherein said antistatic resin comprises a water-soluble polymer, wherein said photo-acid generating agent comprises at least one compound selected from the group consisting of diphenyliodonium trifluoromethanesulfonate, diphenyliodonium perfluorobutanesulfonate, diphenyliodonium hexafluorophosphate, triphenylsulfonium hexafluoroantimonate, triphenylsulfonium hexafluorophosphate, triphenylsulfonium methanesulfonate, triphenylsulfonium trifluoromethanesulfonate, triphenylsulfonium perfluorobutanesulfonate, 1-phenyl-1-(4-methylphenyl)sulfonyloxy-1-benzoylmethane, 1,2,3-trisulfonyloxymethylbenzene, 1,3-dinitro-2-(4-phenylsulfonyloxymethyl)benzene and 1-phenyl-1-(4-methylphenylsulfonyloxymethyl)-1-hydroxy-1-benzoylmethane, and wherein said antistatic resin comprises at least one of basic materials selected from the group consisting of 3-amino-4-methoxybenzenesulfonic acid polymers and polymers having a monomer unit selected from pyrrole-3-(2-ethanesulfonic acid), pyrrole-3-(3-propanesulfonic acid), pyrrole-3-(4-butanesulfonic acid), pyrrole-3-(5-pentanesulfonic acid), pyrrole-3-(6-hexanesulfonic acid), aniline-3-(2-ethanesulfonic acid), aniline-3-(3-propanesulfonic acid), aniline-3-(4-butanesulfonic acid), aniline-3-(5-pentanesulfonic acid), aniline-3-(6-hexanesulfonic acid), aniline-3-(7-heptanesulfonic acid), aniline-3-(2-methyl-3-propanesulfonic acid), aniline-3-(2-methyl-4-butanesulfonic acid), aniline-3-sulfonic acid, aniline-N-(2-ethanesulfonic acid), aniline-N-(3-propanesulfonic acid), aniline-N-(4-butanesulfonic acid), aniline-N-(5-pentanesulfonic acid), aniline-N-(6-hexanesulfonic acid), aniline-N-(7-heptanesulfonic acid), aniline-N-(2-methyl-3-propanesulfonic acid), aniline-N-(2-methyl-4-butanesulfonic acid), 2-aminoanisole-3-sulfonic acid, 2-aminoanisole-4-sulfonic acid, 2-aminoanisole-5-sulfonic acid, 2-aminoanisole-6-sulfonic acid, 3-aminoanisole-2-sulfonic acid, 3-aminoanisole-4-sulfonic acid, 3-aminoanisole-5-sulfonic acid, 3-aminoanisole-6-sulfonic acid, 4-aminoanisole-2-sulfonic acid, 4-aminoanisole-3-sulfonic acid, 2-amino-4-ethoxybenzenesulfonic acid, 3-amino-4-ethoxybenzenesulfonic acid, 2-amino-4-butoxybenzenesulfonic acid, 3-amino-5-butoxybenzenesulfonic acid, 2-amino-4-propoxybenzenesulfonic acid, 3-amino-6-propoxybenzenesulfonic acid, 2-amino-4-isobutoxybenzenesulfonic acid, 3-amino-4-isobutoxybenzenesulfonic acid, 3-amino-4-t-butoxybenzenesulfonic acid, 2-amino-4-t-butoxybenzenesulfonic acid, 2-amino-4-heptoxybenzenesulfonic acid, 3-amino-5-heptoxybenzenesulfonic acid, 2-amino-4-hexoxybenzenesulfonic acid, 3-amino-5-octoxybenzenesulfonic acid, 2-amino-4-nanoxybenzenesulfonic acid, 3-amino-5-decanoxybenzenesulfonic acid, 2-amino-4-undecanoxybenzenesulfonic acid, and 3-amino-5-dodecanoxybenzenesulfonic acid.
