    Abstract: A pressure-sensitive adhesive sheet 1 comprising a base material 11 and a pressure-sensitive adhesive layer 12 has formed therein a plurality of through holes 2 passing through from one surface to the other surface thereof. The through holes 2 have a diameter in a range of 0.1 to 300 µm, and a hole density in a range of 30 to 50, 000 per 100 cm 2 . Moreover, the pressure-sensitive adhesive layer 12 has a storage modulus at T max (the maximum temperature to which the pressure-sensitive adhesive sheet 1 may be exposed after having been stuck onto an adherend) of not less than 4.5×10 3 Pa, and a loss tangent at T max of not more than 0.78. According to the pressure-sensitive adhesive sheet 1, air entrapment and blistering can be prevented or eliminated while securing adequate adhesive strength and with no marring of the appearance, and furthermore air escaping ability is excellent even after being exposed to high temperature after having been stuck onto the adherend.

    Abstract: PROBLEM TO BE SOLVED: To provide a porous net material capable of finely regulating its opening ratio for finely regulating screening effect and sound releasing properties.
    SOLUTION: The porous net material is formed of a porous heat bonding sheet wherein one face of a base material B having fine through-holes is laminated with a hot melt adhesive film F. The through-holes in the base material B are formed in the shape of a grating. In the hot melt adhesive film F, through-holes are formed by cross-linking an adhesive material across the through-holes of the base material B.

    Abstract: PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive sheet which prevents or eliminates air entrapments or blisters and has through-holes formed by heat processing without spoiling the appearance of the pressure-sensitive adhesive sheet. SOLUTION: The pressure-sensitive adhesive sheet 1 is composed of a substrate 11 and a pressure-sensitive adhesive layer 12 and has a plurality of through-holes 2 passing through from one side to the other formed by heat processing. The substrate 11 has a temperature of thermal decomposition peak of ≤450°C at which the rate of weight loss of the substrate 11 becomes largest, when it is heated in a nitrogen environment at an ascending rate of temperature of 20°C/min. The difference in temperature between the peak of heat decomposition and the peak of melting is ≤250°C. COPYRIGHT: (C)2007,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide a self-adhesive tape or sheet excellent in reworking property and operability in correction of a pasted position, and its manufacturing method. SOLUTION: The self-adhesive tape or sheet comprises a support and, formed on at least one face thereof, a self-adhesive layer, where the surface of the self-adhesive layer on at least one face of the support partially has a fibrous projecting structure part. Preferably, the fibrous projecting structure part comprises a napped fiber part having a structure where the fiber rises from the surface of the self-adhesive layer. The self-adhesive tape or sheet is useful as one for pasting a flooring material. The manufacturing method of the self-adhesive tape or sheet comprises flocking the surface of the self-adhesive layer on at least one face of the support by means of a flocking processing method thereby to partially form the fibrous projecting structure part on the surface of the self-adhesive layer.
