A release liner which makes it difficult for an adhesive layer to impair slidability and makes it easy to exhibit an adhesive force suitably, a method of producing a release liner, an adhesive sheet, and a method of producing an adhesive sheet. A release liner has a surface provided with a ridge portion extending linearly, and on the surface, a plurality of recesses having different depths are randomly formed in a surface direction and are continuously connected.

Method of producing an adhesive sheet or a release liner

Release liner, method of producing release liner, adhesive sheet, and method of producing adhesive sheet

An adhesive sheet having high adhesion and removability, low metal corrosion, small outgas generation, and particularly suitable for adherence to an electronic part, which sheet includes an adhesive layer provided for at least one surface of a substrate sheet, in which a pressure-sensitive adhesive forming the adhesive layer includes a resin composition mainly formed of an acrylic copolymer obtained by blending a carboxyl group-free acrylic copolymer obtained by copolymerizing the following components (A) to (C) with (D) an isocyanate-based cross-linking agent: (A) 76.999 to 94.999% by mass of an alkyl(meth)acrylate; (B) 5.0 to 23.0% by mass of an ethylenically unsaturated group-containing morpholine-based compound; and (C) 0.001 to 1.5% by mass of a functional group-containing unsaturated monomer; and a ratio M2/M1 of the mole number (M2) of isocyanate groups in the component (D) to the mole number (M1) of functional groups in the component (C) is 1.5 to 15.0.

Adhesive sheet

An electronic program table processing apparatus can obtain the number of receivable channels M and the standard number of channels N displayable on one screen. When EPG display data is generated, the apparatus examines whether or not the number M is smaller than the number N. If so, the apparatus generates the EPG to display the program information for M channels on one screen. If not, the apparatus generates the EPG to display the program information for N channels on one screen.
