Patent ID: 6861455

Claim:
A composition for a bulkhead of a thin display panel, comprising 85 to 50% by weight of glass or ceramic powder for molding a bulkhead of a thin display panel or apart thereof and 15 to 50% by weight a binder which is an organic additive, wherein said organic additive consists of a resin composition which generates heat energy by in addition with an energy ray and which is cured by energy coming from an energy ray source or the resulting heat energy, said resin composition comprises a photopolymerizable resin component and a photopolymerization initiator system, said photopolymerization resin component being used together with said photopolymerization initiator component to be cured by the energy ray, and said photopolymerization initiator system initiating curing of said photopolymerizable resin component in irradiation with the energy ray, system photopolymerizable resin component being used together with said photopolymerization initiator system to be cured by the energy ray, said photopolymerization initiator system comprises a photo•thermopolymerization initiator which can initiate polymerization by both of light and heat, and said phot•thermopolymerization initiator comprises a sulfonium salt represented by the following general formulae (I), (I′) or (II): wherein R 6 represents hydrogen, halogen, a nitro group, or a methyl group; R 7 represents hydrogen, CH 3 CO or CH 3 OCO; X represents SbF 6 , PF 6 , AsF 6 , BF 4 or B(C 6 F 5 ) 4 , wherein R 1 represents hydrogen, a methyl group, an acetyl group, or a methoxycarbonyl group; R 2 and R 3 each independently represent hydrogen, halogen, or an alkyl group of C 1 to C 1 ; R 4 represents hydrogen, halogen or a methoxy group: R 5 represents an alkyl group of C 1 to C 4 ; and X represents SbF 6 , PF 6 , AsF 6 , BF 4 or B(C 6 F 5 ) 4 .
