摘要:
The adhesive tapes (20) for sticking together printing blankets on a metallic retaining bar or metal rail during a printing process. The adhesive tapes are composed of at least one layer (25), a release liner, and of a melt pressure-sensitive adhesive layer (30) that is applied to said release liner layer on one side. Both sides of the release line layer (25) have the same or different release.

摘要:
The invention relates to an adhesive film comprising at least two adhesive layers (i) and (ii), which differ chemically from one another. The inventive film is characterized in that one layer (i) is suited to bond with epoxy materials and/or polyimides-and the other layer (ii) is suited to bond with polycarbonate, polyethylene, polypropylene, acrylonitrile-butadiene-styrene copolymer plastics, polyethylene terephthalate and/or polyvinylchloride.
摘要:
A pressure sensitive adhesive obtainable by free-radical polymerization, characterized in that at least 65% by weight of the adhesive is based on at least one acrylic monomer from the group of the compounds of the following general formula: where R1=H or CH3 and the radical R2=H or CH3 or is selected from the group consisting of branched or unbranched saturated alkyl groups having 2–20 carbon atoms, the average molecular weight of the adhesive is at least 65,000, applied to a carrier, the adhesive possesses a preferential direction, where the refractive index measured in the preferential direction nMD is greater than the refractive index measured in a direction perpendicular to the preferential direction nCD, the difference Δn=nMD−nCD being at least 1·10−5.

摘要:
The invention relates to a pressure-sensitive adhesive tape, particularly for producing or sticking together optical light crystal data displays (LCD's), comprising a top side and an underside, with light-reflective properties on the top side and light-absorbing properties on the underside. The pressure-sensitive adhesive tape also comprises a carrier film with a top side and an underside, which is provided with a metallic reflective coating on at least one of its sides. The pressure-sensitive adhesive tape is provided with a pressure-sensitive adhesive layer on both sides and is characterized in that the carrier film has a content of antiblocking agents of less than 4000 ppm, and at least one light-absorbing chromophoric layer is provided at least between the underside of the carrier film and the pressure-sensitive adhesive layer located on this side.
摘要:
The invention relates to a contact-adhesive tape, in particular for producing or bonding optical liquid crystal data displays (LCDs), said tape comprising an upper face and an underside. The tape also comprises a backing film (a) with an upper face and an underside, both the upper face and the underside of said tape being provided with a respective contact-adhesive layer (b, b′). The contact-adhesive layer on at least one side of the contact-adhesive tape is black.
摘要:
The invention relates to a pressure-sensitive adhesive tape, particularly for producing LCD displays, comprising two surfaces while also being provided with at least one support having two supporting surfaces and a pressure-sensitive layer on each of the two supporting surfaces. The invention is characterized in that at least one of the two surfaces of the pressure-sensitive adhesive tape has silvery reflective properties.
