Title:
ADHESIVE COMPOSITION, ADHESIVE SHEET AND LAMINATE
Document Type and Number:
WIPO Patent Application WO/2019/004107
Kind Code:
A1
Abstract:
Provided is an adhesive composition which reduces relative permittivity and has better contour conformance when forming an adhesive layer. The present invention concerns an adhesive composition comprising a crosslinkable acrylic polymer, a crosslinking agent and a hydrocarbon polymer, wherein: the mass percentage of the crosslinkable acrylic polymer in the adhesive composition is at least 50%; the hydrocarbon polymer has a number-average molecular weight of 250–15,000; the hydrocarbon polymer assumes a liquid state or an oily state at 20°C; and when the adhesive layer, which is a cured product of the adhesive composition, is formed, the adhesive layer has a relative permittivity of no more than 3.5 at a frequency of 1 MHz. The present invention also concerns an adhesive sheet and a laminate which are formed from the adhesive composition.
