The invention relates to a material web drawing-in apparatus for drawing in a material web. The material web drawing-in apparatus comprises at least one material web holding device for holding the material web to be drawn in, and at least one guide for guiding the at least one material web holding device from a material web drawing-in point to a material web transfer point, and also at least one drawing-in drive which is in connection with the at least one material web holding device and which serves for displacing the at least one material web holding device along the at least one guide upon drawing in the material web to be drawn in in the direction of the material web transfer point.

A release liner for removably covering an adhesive surface is disclosed. The release liner includes a substrate configured in size and shape to cover an adhesive surface of an item. The substrate includes a first side configured to releasably attach to the adhesive surface and a second side opposite the first side. The release liner also includes one or more ink-printed features on the second side of the substrate and a varnish coating on the second side of the substrate. The varnish coating covers at least the one or more ink-printed features on the second side of the substrate.

The optical film with a pressure sensitive adhesive on both sides includes a first pressure sensitive adhesive layer having a thickness of 3 μm to 30 μm on first main surface of an optical film, and a second pressure sensitive adhesive layer having a thickness of 50 μm or more on second main surface of the optical film. A first protective sheet and a second protective sheet are releasably attached on the first pressure sensitive adhesive layer and the second pressure sensitive adhesive layer, respectively. The residual stress of the second pressure sensitive adhesive layer S.sub.2 (N/cm.sup.2), the thickness of the first protective sheet Y (μm); and the thickness of the second protective sheet Z (μm) satisfy the following relationship: 20≦Y≦80; 45≦Z; and Y+0.17 Z+10.6 S.sub.2≧63.

A substrate-free adhesive tape that is excellent in adhesive physical properties and is suitable for a continuous process is provided. The substrate-free adhesive tape includes a release film, and an adhesive layer provided on one surface of the release film and the adhesive layer containing a cured product of an adhesive composition, wherein when the release film is fixed on the outer surface of a semicircular tip part of a jig, the semicircular tip part having a radius of 22.5 mm, a breaking distance of the adhesive layer is 110 mm or less when the adhesive layer is stretched at a rate of 20 m/min from a semicircular center of the semicircular tip part toward an outermost direction of the semicircular tip part.

In the present invention, compounding an addition-reaction-curable organopolysiloxane composition with a specific amount of an organopolysiloxane compound that has three or more (meth)acryl groups in the molecule and a weight-average molecular weight of 1,000 or greater yields an organopolysiloxane composition for use in a release paper or release film in which addition reactions can occur using a small amount of platinum family metal catalyst, cured films can be formed having a peeling strength approximating levels encountered in the past, and addition-reaction-prompted curing will proceed even on a base material containing a catalyst-poisoning component.

Provided is an adhesive film for a display, in which the adhesive film has a high absorption capacity in a near infrared region and maintains a high transmittance in a visible region, thereby guaranteeing visibility.

A cellulose fiber-based substrate, at least one side of which is coated with an aqueous mixture composed of: a) at least one water-soluble polymer (WSP) containing hydroxyl groups, b) at least one lactone substituted with at least one linear or branched and/or cyclic C.sub.8-C.sub.30 hydrocarbon chain which may contain heteroatoms, c)at least one crosslinking agent. A method of production and use thereof.
