The film comprises a copolymer was copolymerized of monomers which comprise at least one unsaturated carboxylic acid monomer, at least one epoxy group-containing unsaturated monomer, and at least one cinnamoylphenyl group-containing unsaturated monomer. The reflection preventing film exhibits a high halation preventing effect, involves no sublimation of radiation absorbing components contained therein, is free from occurrence of intermixing, possesses excellent heat resistance, exhibits a superb dry etching performance and storage stability, and produces resist patterns with excellent resolution and precision. The resist pattern forming process comprises forming the reflection preventing film on a substrate, forming a resist coating film on said reflection preventing film, irradiating the resist film with a radiation, and developing the resist coating film.

摘要： A magnetic recording medium having excellent stability of recorded magnetic signals and capable of recording magnetic signals by a thermally assisted magnetic recording system in which a magnetic recording layer of the magnetic recording medium contains ferromagnetic crystal grains of a Co—Ni—Pt alloy with a Pt content of 44 at % or more and 55 at % or less and with an atom content ratio: Ni/(Co+Ni) of 0.64 or more and 0.8 or less. The magnetic recording medium has extremely excellent stability of recorded magnetic signals since the Co—Ni—Pt alloy constituting the magnetic recording layer has an extremely high anisotropy field at a normal temperature. Further, the magnetic recording medium can perform signal recording based on the thermally assisted magnetic recording system since the Co—Ni—Pt alloy constituting the magnetic recording layer has a Curie point within an appropriate temperature range.
