Abstract: An adhesive sheet which can be produced without using a release sheet having an uneven surface form and which can prevent or remove air bubbles and blisters and a process for producing the same are provided by an adhesive sheet prepared by laminating a non-permeable adhesive layer in which both surfaces are flat on an uneven surface of a base material having concave and convex parts in which adjacent concave parts are communicated with each other at least on one surface so that the adhesive layer is brought into contact with the convex part of the base material and a process comprising laminating a release sheet provided on a release treated surface with a non-permeable adhesive layer in which both surfaces are flat and a base material having concave and convex parts in which adjacent concave parts are communicated with each other at least on one surface so that the non-permeable adhesive layer is brought into contact with the convex part of the base material.

Abstract: A pressure sensitive adhesive sheet for marking which comprises a substrate of a non-vinyl chloride-based resin, a pressure sensitive adhesive layer disposed on one face of the substrate and a crosslinked acrylic urethane-based coating layer which comprises (A) an acrylic polyol resin modified with a polyester and having a weight-average molecular weight of 15,000 to 80,000 and (B) a polyisocyanate-based compound as the curing agent and is disposed on the other face of the substrate. The pressure sensitive adhesive sheet is a sheet using a non-vinyl chloride-based substrate which meets environmental requirements, exhibits excellent resistance to scratches, resistance to dipping into chemicals, resistance to cracks under stretching and weatherability and a desired gloss and can be advantageously used, for example, for automobiles.

Abstract: A pressure sensitive adhesive sheet 1 comprises a base material 11 and a pressure sensitive adhesive layer 12, and has a plurality of through-holes 2 formed therein passing through one face to another face, such that the hole diameter of the through-holes 2 on the surface of the base material 11 is 0.1 to 42 ?m, the outer diameter of a recess 21 at the peripheral edge of the through-holes 2 on the surface of the base material 11 is not greater than 60 ?m, and the modulus of elasticity in tension of the base material 11 is 190 to 600 MPa. The through-holes of the pressure sensitive adhesive sheet 1 allow preventing or eliminating an air trapping and a blister, while the pressure sensitive adhesive sheet 1 exhibits good appearance, with the through-holes being invisible to the naked eye, even when the pressure sensitive adhesive sheet 1 is stretched.

Abstract: A masking tape 1, which is a masking tape 1 for a long part, comprises a base material 11 and a pressure sensitive adhesive layer 12, such that the tearing resistance of the base material 11 in the width direction is 220 mN/15 mm or more. Preferably, in particular, the base material 11 comprises a material in which a machine direction is generated during manufacture, the machine direction of the base material 11 is the longitudinal direction of the masking tape 1, and the tearing resistance of the base material 11 in a direction perpendicular to the machine direction is 220 mN/15 mm or more. Tape breakage is difficult to occur in such a masking tape 1.

Abstract: In a pressure-sensitive adhesive sheet 1 that comprises a base material 11 and a pressure-sensitive adhesive layer 12, and has formed therein by thermal processing a plurality of through holes 2 passing through one surface to the other surface of the pressure-sensitive adhesive sheet 1, as the base material 11, one is used for which, upon heating at a heating rate of 20° C./min under a nitrogen atmosphere, the temperature at a thermal decomposition peak where the mass reduction is greatest is not more than 450° C., or the difference between the temperature at the thermal decomposition peak and the temperature at a melting peak is not more than 250° C. According to this pressure-sensitive adhesive sheet 1, the appearance of the pressure-sensitive adhesive sheet 1 is not marred by the through holes 2 formed by the thermal processing.

Abstract: A pressure-sensitive adhesive sheet for automobile marking comprising a substrate 11 and a pressure-sensitive adhesive layer 12, wherein the substrate 11 has a storage elastic modulus at 60 to 80° C. of 7.0×101 MPa or more, and preferably a storage elastic modulus at 5 to 10° C. of 1.0×102 to 1.0×103 MPa. As a result there can be obtained a pressure-sensitive adhesive sheet for automobile marking that allows preventing blistering even when used at high temperatures of about 60 to 80° C., without restrictions regarding a pressure-sensitive adhesive composition, and with no need for a primer to be applied to an adherend.
