Title:
SHEET-SHAPED EPOXY RESIN COMPOSITION, AND SEALING SHEET CONTAINING SAME
Document Type and Number:
WIPO Patent Application WO/2013/027389
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a resin composition that is for a sheet, has superior adhesion to optical elements and the like and transparency after curing, and resists incorporation of air at the interface between an element and the resin composition for a sheet during thermocompression bonding. The sheet-shaped epoxy resin composition contains (A) an epoxy resin having a weight average molecular weight of 2000 to 1×105 and (B) a curing accelerator, and the storage elastic modulus (G'(50)) at 50°C and the storage elastic modulus (G'(80)) at 80°C satisfies G'(50)/G'(80) < 11, G'(80) being 2500 to 5×105 Pa.
