Title:
PHOTOSENSITIVE RESIN COMPOSITION AND PHOTOSENSITIVE DRY FILM RESIST AND PHOTOSENSITIVE COVER RAY FILM USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2002/097532
Kind Code:
A1
Abstract:
A photosensitive resin composition comprising a soluble polyimide, a compound having a carbon−carbon double bond and a photoreaction initiator and&sol or photosensitizer as main components&semi a photosensitive dry film resist using the composition&semi and a photosensitive dry film resist exhibiting excellent flame retardance. The resin composition affords a photosensitive dry film resist and a photosensitive cover ray film which exhibits good workability, can be developed with an alkaline solution, and satisfy the flame retardancy standard UL94V−0. Further, the film can be directly laminated without the use of an adhesive and is excellent in heat resistance, and thus can be suitably used as a photosensitive cover ray film for a printed board for use in electronic materials, a suspension for a hard disk, and the head portion of a hard disk in a personal computer.
