    Abstract: Provided is a novel pressure-sensitive adhesive tape having a moderately weak adhesion during a time period from a production process (during its production) to the time of the accomplishment of the product as a result of the completion of the production (immediately after the production). Accordingly, the peeling failure, or the like, resulting from strong adherence of a pressure-sensitive adhesive layer to a roll or the like at the time of the production can be sufficiently suppressed. As a result, stable product supply can be performed. In addition, even after the lapse of about a half day from immediately after the production, the pressure-sensitive adhesive tape can be easily rewound. On the other hand, the pressure-sensitive adhesive tape can express a sufficiently strong adhesion for an adherend after the lapse of a predetermined time from the production (e.g., at the time of its use). The pressure-sensitive adhesive tape of the present invention includes at least three layers including: a base material layer (A); a first pressure-sensitive adhesive layer (B1); and a second pressure-sensitive adhesive layer (B2) in the stated order, in which: the base material layer (A) contains a thermoplastic resin; the first pressure-sensitive adhesive layer (B1) contains a tackifier at a content of 12 wt % or more; the second pressure-sensitive adhesive layer (B2) contains a tackifier at a content of 10 wt % or less; and the second pressure-sensitive adhesive layer (B2) has a thickness of 10 μm or more.

    Abstract: The present invention relates to an acrylic pressure-sensitive adhesive composition containing an acrylic polymer and a tackifier obtained by acid modification of a tackifier resin inherently free of an acid component; a pressure-sensitive adhesive tape including a substrate made of a film comprising an olefin polymer or a thermoplastic resin containing a carbonyl oxygen atom in the molecular skeleton, and the acrylic pressure-sensitive adhesive composition on at least one surface of the substrate, and the like. The invention provides an acrylic pressure-sensitive adhesive composition having high adhesive strength (particularly initial adhesive strength) to an adherend having lower polarity, such as an olefin polymer heretofore been considered poorly adhesive, wherein degradation of the adhesive strength after heating and preservation has been suppressed, as well as a pressure-sensitive adhesive tape comprising the composition. The pressure-sensitive adhesive tape of the present invention is also useful for binding.

    Abstract: Provided is such a pressure-sensitive adhesive tape as described below, which is capable of protecting the uneven surface of a member having unevenness on its surface. The pressure-sensitive adhesive tape brings together sufficient pressure-sensitive adhesiveness for, and sufficient releasability from, the member. In addition, even upon deformation of the member protected with the pressure-sensitive adhesive tape by, for example, lamination or continuous winding, the uneven shape does not deform and a base material layer in the pressure-sensitive adhesive tape is not damaged. Also provided is a pressure-sensitive adhesive tape useful as such a surface protective film for a prism sheet as described below, which is capable of effectively protecting, for example, a lens surface of a prism sheet having multiple triangle pole-shaped prisms fixed on its surface. The surface protective film brings together sufficient pressure-sensitive adhesiveness for, and sufficient releasability from, the prism sheet. In addition, when the prism sheet protected with the surface protective film is brought into a state such as a laminated state or a continuously wound state, the emergence of irregularity (indentation) in the external appearance of the prism sheet to which the surface protective film is attached can be suppressed. A pressure-sensitive adhesive tape of the present invention is a pressure-sensitive adhesive tape including a base material layer, a first pressure-sensitive adhesive layer, and a second pressure-sensitive adhesive layer in the stated order, in which: the base material layer contains a thermoplastic resin; the storage modulus of the first pressure-sensitive adhesive layer is higher than the storage modulus of the second pressure-sensitive adhesive layer; and a difference between the storage modulus of the first pressure-sensitive adhesive layer at a frequency of 10 Hz and 23° C., and the storage modulus of the second pressure-sensitive adhesive layer at a frequency of 10 Hz and 23° C. is 3×105 Pa or more.
