Title:
PHOSPHAZENE COMPOUND, PHOTOSENSITIVE RESIN COMPOSITION AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2005/019231
Kind Code:
A1
Abstract:
A phosphazene compound and photosensitive resin composition suitable for production of wiring boards, having such characteristics that no halogenated flame retardants are used; a water base development can be made; desirable pattern morphology can be realized; a balance can be struck between properties such as thermal stability, resistance to hydrolysis, processability and adherence on the one hand and photosensitivity, flame resistance and mechanical strength on the other hand; and they can meet the demand for miniaturization and weight reduction of electronic parts. There is provided a phosphazene compound that has in its molecule an unsaturated double bond resulting from reaction of phenoxyphosphazene compound having a phenolic hydroxyl and/or crosslinked phenoxyphosphazene compound obtained by crosslinking of the phenoxyphosphazene compound with epoxy compound having an unsaturated double bond and/or isocyanate compound. Furthermore, there is provided a photosensitive resin composition comprising the phenoxyphosphazene compound and at least carboxylated and/or hydroxylated soluble polyimide resin, and further comprising (meth)acrylic compound.
