Abstract:
The invention is an adhesive composition comprising a modified polyolefin-based resin in an amount of 45 mass % or more based on a total solid content of the adhesive composition and satisfying the specific following equation (I): α 1 /β 1 ≥0.20  (I) [α 1  represents a 180° peel adhesion strength (N/25 mm) as measured using the following measurement sample (A) under an environment at 85° C. in accordance with JIS Z0237: 2009, and β 1  represents a water vapor permeability (g·m −2 ·day −1 ) as measured using the following measurement sample (B) under a condition at 40° C. and a relative humidity of 90%]. One aspect of the invention provides an adhesive composition capable of obtaining a sealant excellent in sealing performance, a sealing sheet having an adhesive layer made by using the adhesive composition, and a sealed body obtained by sealing a seal subject with the sealing sheet.

Claim (Index 1):
An adhesive composition comprising a modified polyolefin-based resin in an amount of 45 mass % or more based on a total solid content of the adhesive composition and satisfying the following equation (I):\n \u03b1 1 /\u03b2 1 \u22650.20\u2003\u2003(I) [\u03b1 1  represents a 180\u00b0 peel adhesion strength (N/25 mm) as measured using the following measurement sample (A) under an environment at 85\u00b0 C. in accordance with JIS Z0237: 2009, and \u03b2 1  represents a water vapor permeability (g\u00b7m \u22122 \u00b7day \u22121 ) as measured using the following measurement sample (B) under a condition at 40\u00b0 C. and a relative humidity of 90%];\n Measurement sample (A): a measurement sample obtained by the following steps (a1) to (a3);\n [Step (a1)] a step in which a polyethylene terephthalate sheet with a thickness of 50 \u03bcm is laid on an adhesive layer of an adhesion sheet having a layer structure of an adhesive layer with a thickness of 25 \u03bcm obtained by using a release sheet (I)/adhesive composition, which is subsequently laminated at 40\u00b0 C. and a laminating rate of 0.2 m/min to obtain a laminate (I); \n [Step (a2)] a step in which the release sheet (I) of the laminate (I) obtained in step (a1) is peeled off to expose the adhesive layer, and a glass plate is laid on the adhesive layer, which is subsequently laminated at 40\u00b0 C. and a laminating rate of 0.2 m/min to obtain a laminate (II); and \n [Step (a3)] a step in which the laminate (II) obtained in step (a2) is heated at 100\u00b0 C. for 2 hours, and then allowed to stand at 23\u00b0 C. for 24 hours; and \n \n Measurement sample (B): an adhesive layer with a thickness of 50 \u03bcm obtained by using the adhesive composition.
