<P>PROBLEM TO BE SOLVED: To provide a radiation-sensitive dry film having excellent storage stability after a dry film is formed, from which a microlens satisfying various characteristics even at a low heating temperature is formed. <P>SOLUTION: The radiation-sensitive dry film includes: a base film; a radiation-sensitive resin composition layer layered on the base film and containing (A) an alkali-soluble polymer, (B) a polymerizable unsaturated compound, (C) a photo-polymerization initiator and (D) a compound having an oxiranyl group, an episulfide group or an oxetanyl group; and a cover film layered on the radiation-sensitive resin composition layer. The film contains, as the (A) alkali-soluble polymer, a copolymer of (a1) a polymerizable unsaturated compound having an acidic functional group and (a2) a polymerizable unsaturated compound comprising a specified compound represented by S-(tetrahydropyran-2-yl) thiomethacrylate. <P>COPYRIGHT: (C)2010,JPO&INPIT |
