    Abstract: The present disclosure relates to an electronic device comprising at least one organic light-emitting diode and a pressure sensitive adhesive composition comprising a synthetic rubber block (co)polymer, and wherein the pressure sensitive adhesive composition has: a) a relative permittivity no greater than 2.50, when measured at an alternating current frequency of 100 kHz according to the test method described in the experimental section; b) a water uptake no greater than 0.60 wt %, when measured after exposure to 60° C. and 95% relative humidity for 120 hours, according to the test method described in the experimental section; and c) optionally, a peel adhesion value above 0.20 N/mm, when measured at 85° C. according to the test method described in the experimental section. In another aspect, the present disclosure is directed to a method of manufacturing an electronic device comprising at least one organic light-emitting diode, wherein the method comprises the step of using a pressure sensitive adhesive composition as described above. According to still another aspect, the present disclosure is directed to the use of a pressure sensitive adhesive composition as described above for protecting organic light-emitting devices or organic light-emitting diodes from moisture and air permeation.

    Abstract: The present invention relates to a pressure-sensitive adhesive composition comprising an acrylate copolymer having a side carboxyl that is formed by a first monomer mixture containing a carboxyl-containing monomer, wherein, the content of the carboxyl-containing monomer is 0.1-10 wt. % based on the total weight of the first monomer mixture for forming the acrylate copolymer having the side carboxyl, the glass transition temperature Tg of the acrylate copolymer having the side carboxyl is larger than or equal to −55° C. and less than or equal to −30° C. The pressure-sensitive adhesive composition further comprises 1-25 wt. % of an acrylate oligomer with a weight-average molecular weight greater than or equal to 20,000 Da and a glass transition temperature Tg greater than or equal to 25° C., and 1-20 wt. % of a terpene tackifying resin based on the total weight of the acrylate copolymer having the side carboxyl and the acrylate oligomer. The pressure-sensitive adhesive composition also has a high peel force at room temperature and a high cohesive force at high temperature and has excellent anti-warping and anti-bubbling properties

    Abstract: The present invention is directed to a multilayer pressure sensitive adhesive (PSA) film, having a first pressure sensitive adhesive layer and at least an opposing layer, wherein the first pressure sensitive adhesive layer comprises a pressure-sensitive adhesive composition with a (meth)acrylic-based elastomeric material comprising a reaction product of polymerizable material comprising: (a) a first monomer which is an alkyl (meth)acrylate ester of a primary alcohol R1—OH, the alkyl (meth)acrylate ester being of Formula (I) CH2═C(R2)—(CO)—OR1   (I) wherein R1 is an alkyl having 14 to 25 carbon atoms and the primary alcohol R1—OH has an iso index equal to at least 2 but no greater than 4; R2 is hydrogen or methyl; and (b) a second monomer having an ethylenically unsaturated group; wherein the at least one opposing layer comprises at least one filler material. The invention is also directed to a method for the manufacturing of such a multilayer PSA film and its use.
