<p>The photocurable composition for a sealant of the present invention includes a compound represented by general formula (1):
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒA 1 -Y 1 -B 1 -Y 2 -A 2 €ƒ€ƒ€ƒ€ƒ€ƒ(1)
(wherein A 1 and A 2 each represents, independently, a monovalent group having a cyclic À-electron conjugated structure;
Y 1 and Y 2 each represents, independently, a divalent group represented by general formula (4); and
B 1 represents (i) a divalent alicyclic hydrocarbon group, (ii) a divalent aromatic hydrocarbon group, (iii) a divalent heterocyclic group, (iv) a divalent aliphatic hydrocarbon group of 1 to 6 carbon atoms, or (v) a divalent group in which two or more group selected from the group consisting of a divalent alicyclic hydrocarbon group, a divalent aromatic hydrocarbon group, a divalent heterocyclic group, a divalent aliphatic hydrocarbon group of 1 to 6 carbon atoms, a carbonyl group, an ether group, a thioether group, and a SO 2 group are linked).</p> |
