Document Type and Number:
WIPO Patent Application WO/2015/098647
Kind Code:
A1
Abstract:
The present invention provides a sheet-like sealing material formed from at least one sealing resin layer, wherein: the water vapour transmission rate at a temperature of 40°C and a relative humidity of 90% is not more than 20 g/(m2∙day) when converted to the equivalent thereof at a thickness of 50 µm; the b* value of the sheet-like sealing material in the CIE L*a*b* colour system specified in JIS Z 8729-1994 is -2 to 2%; and the light transmittance of the sheet-like sealing material at a wavelength of 370 nm is not more than 1%, and the light transmittance at a wavelength of 420 nm is at least 85%. The present invention also provides: a sealing sheet having the sheet-like sealing material and a gas barrier layer; an electronic-device sealing body obtained by using the sheet-like sealing material or the sealing sheet as a sealing material; and an organic electroluminescent element having the sheet-like sealing material. According to the present invention, provided are: a sheet-like sealing material exhibiting excellent moisture barrier properties, light resistance, and colourless transparency; a sealing sheet having the sheet-like sealing material and a gas barrier layer; an electronic-device sealing body; and an organic electroluminescent element.
