    摘要: One aspect of the present invention is a pressure-sensitive adhesive which comprises 100 parts by mass of (A) an acrylic polymer having a glass transition temperature of -50 to -25°C, 0.01-3 parts by mass of (B) a silane coupling agent having an epoxy group, 0.01-0.9 parts by mass of (C) a compound having two or more epoxy groups in the molecule, and 0.01-0.5 parts by mass of (D) an organic polyvalent-metal compound. Another aspect of the present invention is a decorative sheet which includes a layer comprising the pressure-sensitive adhesive. Still another aspect of the present invention is the front panel of a door for opening/closing the front part of an article main body, the panel comprising (α) a layer of either a glass or a transparent resin sheet, (β) a layer comprising the pressure-sensitive adhesive, and (γ) a layer of a resin film, in this order from the front side of the article. A further aspect is the front panel of a door for opening/closing the front part of an article main body, the panel comprising (γ) a layer of a resin film, (β) a layer comprising the pressure-sensitive adhesive, and (α) a layer of either a glass or a transparent resin sheet, in this order from the front side of the article.

    摘要: The invention relates to a joining method in which a first surface (2) of a first joining part (1) and a second surface (8) of a second joining part (6) are bonded to each other, in which an adhesive tape (3) with a first side (4) and a second side (7) is made available, and a first activatable adhesive is arranged on the first side (4) and a second activatable adhesive, which is an activatable pressure-sensitive adhesive, is arranged on the second side (7), the first side (4) of the adhesive tape (3) is brought into contact with the first surface (2) of the first joining part (1) and a preliminary assembly is produced, the second surface (8) of the second joining part (6) is joined in a joining movement to the second side (7) of the adhesive tape (3) and the joining movement has a tangential component and a perpendicular component with respect to the second side (7) of the adhesive tape (3), and a ratio between tangential component and perpendicular component is greater than 0.5, wherein a contact area between second surface (8) of the second joining part (6) and second side (7) of the adhesive tape (3) is provided with a non-aqueous lubricant.
