Abstract:
A splicing tape and a method of using such tape to equip a wound roll for flying splice. The tape includes a first and second carrier and two strips of laminating composition disposed between them, each strip joining the first carrier to the second carrier. The carriers have a first and a second layer of pressure-sensitive, laminating composition and a first and a second layer of pressure-sensitive adhesive. The strips of laminating composition are disposed such that they are not in direct contact with one another. They form a predetermined breakage point. The splicing tape is adhered to the roll such that part of the first layer of pressure-sensitive adhesive forms a first bonding area, the end region of the uppermost ply of the wound roll, and the second layer of pressure-sensitive adhesive forms a second bonding area to the roll, which is located partly below the first bonding area.
Abstract:
Provided is a process for producing an organic EL panel by using an ultrathin glass plate, in which the ultrathin glass plate is not “fractured” or “cut” in the production process, the organic EL element is formed reliably when formed by vacuum deposition, and recovered without damage after the production process, and there is no need for installing an additional step of cleaning the rear face of the ultrathin glass plate. The process for producing an organic EL panel according to the present invention is a process for producing an organic electroluminescent panel by forming an organic electroluminescent element on an ultrathin glass plate by vacuum deposition method, comprising forming electrodes on the ultrathin glass plate, by temporarily fixing the ultrathin glass plate to a supporting plate via a double-sided adhesive tape having a thermal release adhesive layer formed at least on one face of the base material layer, containing heat-expandable microspheres that start expansion and/or foaming at temperature higher than the vacuum deposition temperature.
Abstract:
A double-sided pressure-sensitive adhesive tape includes a nonwoven fabric substrate and pressure-sensitive adhesive layers present on both sides of the substrate, in which the nonwoven fabric substrate contains at least Manila hemp, has a thickness of 18 μm or less, and has a tensile strength in a machine direction of 4 N/15 mm or more. The double-sided pressure-sensitive adhesive tape is thin and is effective for the reduction in size and thickness of products to be fixed through the tape. The tape has a high strength in the machine direction and does not break during production and processing processes. In addition, the tape has a nonwoven fabric substrate and thereby excels also in punching quality. The tape is therefore particularly useful as a double-sided pressure-sensitive adhesive tape for fixing a wiring circuit board.

Abstract:
The invention relates to a polyacrylate which as a result of a polymerization process has a broad, bimodal molecular weight distribution. These acrylate pressure-sensitive adhesives are preferably processed from the melt. The low molecular weight fraction lowers the flow viscosity, while the high molecular weight fraction results in the achievement of a high shear strength, following appropriate crosslinking, for the acrylate pressure-sensitive adhesive.
