    Abstract: A double coated pressure sensitive adhesive tape comprising pressure sensitive adhesive layers which comprise an acrylic ester-based copolymer having a weight-average molecular weight of 700,00 or greater and a content of a butyl acrylate unit of 90% by mass or greater and 40 to 60% by mass of a tackifier as main components and are disposed on both faces of a core material, wherein the thickness of the entire tape including the core material and the adhesive layers is 30 μm or smaller, and the thickness of the adhesive layer on each face is 2 to 10 μm. The tape is transparent and thin, is advantageously used for fixing members of portable terminals such as portable telephones and PDA and thin film displays, laminating substrates in optical disks and fixing polarizing plates and exhibits excellent adhesive strength and holding power at high temperatures.

    Abstract: A substrate-less double face adhesive tape comprises a sticky layer set having a first sticky layer, a second sticky layer and a third sticky layer; and the adhesions of the first sticky layer and third sticky layer being stronger than that of the second sticky layer; a first separable paper adhered upon an upper surface of the first sticky layer; and a second separable paper adhered upon a lower surface of the third sticky layer. The first sticky layer and third sticky layer are made from material selected from water acrylic glue, PU resin, and PU-acrylic glue and the second sticky layer is made of lower adhesion water-solvable glue.
