COMPOSITION FOR COATING, HARD COAT FILM AND OPTICAL RECORDING MEDIUM

摘要

A coating composition containing reactive particles (A) in which an organic compound having at least one polymerizable unsaturated group in a molecule thereof is chemically bonded to inorganic oxide particles, an organic compound monomer or oligomer (B) having a polyethylene oxide chain (content in molecule: not less than 50% and less than 100%) and at least two polymerizable unsaturated groups in a molecule thereof and not having an aromatic ring and an alkyl chain having seven or more carbon atoms, an organic compound monomer or oligomer (C) having at least two polymerizable unsaturated groups in a molecule thereof, being an organic compound monomer or oligomer other than the organic compound monomer or oligomer (B), and a siloxane compound (D) having a dialkyl siloxane backbone is applied onto one surface of a base material film 11, and cured by irradiating with ionizing radiation, so as to form a hard coat layer 12 of thickness from 0.1 to 20 µm. This hard coat layer 12 has both excellent fingerprint wipability and excellent antistatic performance.
