Abstract:
To provide a radiation curable pressure sensitive adhesive sheet capable of yielding both a pressure sensitive adhesive sheet with good initial adhesion to an adherend before irradiation and a pressure sensitive adhesive sheet with good rigidity after irradiation. A radiation curable pressure sensitive adhesive sheet includes a (meth)acrylic copolymer having a radiation reactive site and a plasticizer capable of bonding with the (meth)acrylic copolymer upon being irradiated.
Abstract:
A method of making a display assembly includes the steps of (a) attaching a first substrate and a second substrate with an optically clear heat activated adhesive to form a laminate. Each of the first and second substrate has opposing major surfaces. At least one of the first and second substrate has a three dimensional surface topography covering at least a portion of one of its major surfaces or is distortion sensitive. At a heat activation temperature, the adhesive is pressure sensitive. The method also includes heating the laminate to the heat activation temperature of the adhesive causing the adhesive to flow. The activation temperature is greater than 40°C and less than 120°C.
Abstract:
The present invention provides a release material formed by irradiating a release material precursor having a shear storage modulus of about 1x10 to about 3x10 Pa at 20 DEG C and a frequency of 1 Hz, wherein the release material has a contact angle of 15 DEG or more, measured using a mixed solution of methanol and water (volume ratio: 90/10) having a wet tension of 25.4 mN/m. The release material of the present invention has improved anchoring to certain substrates, ensuring relatively low release strength from certain pressure-sensitive adhesives, particularly even after the exposure to a high temperature. Thus, the release materials are capable of allowing the pressure-sensitive adhesive to maintain stable residual adhesion strength.
Abstract:
Problem: To provide an optically clear adhesive with a high dielectric constant having an excellent balance of adhesive strength and cohesive strength as well as excellent optical characteristics, and an optical laminate containing the same. Solution: The optically clear adhesive of an embodiment of the present disclosure comprises a polymer of an acrylic monomer composition containing a hydroxyl group-containing monomer and at least 0.09 mass% and less than 50 mass% of a monofunctional alkyl (meth)acrylate, wherein the number of moles of OH in 100 g of the adhesive is at least 0.3 and at most 0.90.
Abstract:
A thermally cured polyimide is provided, and in particular a crosslinked polyimide, comprising a fluorenyl diamine and comprising an aromatic ring having at least one C1-C10 branched or unbranched alkyl substituent, where the alkyl substituent includes a benzylic hydrogen. The present invention provides a crosslinked polyimide made by a process comprising the step of crosslinking a polyimide comprising diamines comprising pendent fluorenyl groups and comprising aromatic rings having at least one C1-C10 branched or unbranched alkyl substituent, the alkyl substituent including a benzylic hydrogen, by raising the temperature of said polyimide above its glass transition temperature.
