To provide a baseless double-sided adhesive sheet or tape that is configured such that adhesive does not exude during storage, or moreover during slitting to a predetermined size, or the like, and that is also capable for exhibiting the desired performance of having a cohesive force that resists peeling, without sacrificing the initial adhesive strength, and to provide a method for manufacturing the same.

In the baseless double-sided adhesive sheet or tape, an adhesive layer formed from an adhesive serves as a center layer, and adhesive layers and formed from an adhesive are layered onto a front face and a rear face of the adhesive layer serving as the center layer. Fibers are least dispersed in the adhesive layer serving as the center layer, and the adhesive layer serving as the center layer between the adjacent adhesive layers has a relatively high fiber density and relatively low flowability.

The present invention relates to an optically anisotropic sheet comprising a substrate and a liquid crystal cured layer laminated together, wherein the substrate has a surface roughness of 1.0 nm or less in a field of view of 1 μm.sup.2 and a water contact angle of 70° or more.

Lamination transfer films and methods for transferring a structured layer to a receptor substrate. The transfer films include a carrier substrate having a releasable surface, a sacrificial template layer applied to the releasable surface of the carrier substrate and having a non-planar structured surface, and a thermally stable backfill layer applied to the non-planar structured surface of the sacrificial template layer. The sacrificial template layer is capable of being removed from the backfill layer, such as via pyrolysis, while leaving the structured surface of the backfill layer substantially intact.

A multilayer tape assembly is described which can be used with insulation jacketing and particularly for self sealing lap (SSL) applications. The tape assembly includes two adhesive layers with associated carrier and release layers in conjunction with a differential release system. Various methods of use are also described.

A method of making absorbent foam composites and absorbent foam composites produced therefrom. The method comprises casting an absorbent foam layer having a first side and a second side opposite the first side onto a barrier layer having a first side and second side opposite the first side, where the second side of the absorbent foam layer is in contact with the first side of the barrier layer; joining a second absorbent layer to the second side of the barrier layer before, during, or after the casting step; and breaching the barrier layer after the casting step so that the foam layer and second absorbent layer are in fluid communication. The absorbent foam composites can be used in a variety of applications, including personal hygiene articles, medical bandages, pet pads and agricultural pads.

An object of the present invention is to provide a laminated member for decoration that can be molded into a complicated shape and has a superior hardcoating property. The present invention relates to a laminated member for decoration having a protective film, a coating layer and a resin substrate, wherein the surface roughness Rz(a) of the adhesive layer of the protective film on the side where the coating layer is located and the surface roughness Rz(b) of the coating layer of an unheated sample formed by peeling the protective layer, the surface roughness being taken on the side opposite from the resin substrate, define Rz(b)/Rz(a)×100 having a prescribed relationship; the surface roughness Rz(b) and the surface roughness Rz(bh) of the coating layer of a heated sample prepared by heating the unheated sample under a prescribed condition, the surface roughness being taken on the side opposite from the resin substrate, satisfy at least one of Formulas (2) and (3) below:

0%≤Rz(bh)/Rz(b)×100<30%  (2), and

0≤Rz(bh)≤Rz(b)<0.5 μm  (3);

and the unreacted (meth)acryloyl groups of the coating layer of the heated sample irradiated with a prescribed amount of active energy rays have disappeared 10 to 100% as compared with the coating layer of the unheated sample.

A device for translaminating tension-sensitive films from a first liner to a second liner, wherein the device has a first transport device, a second transport device, and a laminating device. The first transport device is configured to transport a first laminated strip to a film delaminating station. The second transport device is configured to transport a second strip-shaped liner to the laminating device, which is designed to laminate the tension-sensitive film onto the second liner in order to form a second laminated strip. The first transport device and the laminating device are arranged relative to each other such that the tension-sensitive film is pulled off at the film delaminating station in the direction opposite the running direction of the first laminated strip at said station.

Exemplary embodiments of the present disclosure are directed towards methods and apparatus for molding-in gaskets that serve as light blockers, within the grooves of a moving planar work material. The gaskets comprise of a hot melt adhesive material that is in a molten state above a particular temperature and gets solidified below a particular temperature. Another exemplary embodiment of the present disclosure is directed towards a planar work material having grooves that are filled with molded-in gaskets, wherein the gaskets are made up of a hot melt adhesive material. The gaskets made of the hot melt adhesive material bond securely with the panels because of inherent adhesive properties, and provide structural stability to the light panels. Another exemplary embodiment of the present disclosure is directed towards the use of a hot melt adhesive material as the molding material for molding-in gaskets within the grooves of a planar work material.

A thin ribbon spirally wound polymer conduit and method of forming, wherein a helical reinforcing bead is interposed adjacent overlapping layers of ribbon. Further, a method of continuously forming spirally wound conduit wherein a sacrificial layer, preferably having a different base polymer to that of the conduit, is first applied to the former before the conduit is formed overtop.

A method for making a coated fabric includes the steps of: applying a coating solution of a resin in an organic solvent to a roller-conveyed non-stretchable and releasable substrate web to form a coating layer; laminating a roller-conveyed base fabric to the coating layer to form a laminate; guiding the laminate to pass through at least one tank containing water to immerse the laminate in water such that the coating layer is solidified and the organic solvent contained in the coating layer is replaced by water; and removing water from the coating layer by drying to leave micropores in the coating layer.
