The transfer portion may include at least (i) a printable layer in contacting relationship with the carrier layer, and (ii) an ink layer positioned such that the printable layer is between the carrier layer and the ink layer.

Provided is a heat-resistant shrinkable adhesive film capable of reducing or preventing defects such as shrinkage when exposed to a high temperature even when bonded in a highly stretched state. A heat-resistant shrinkable adhesive film according to one embodiment of the present disclosure includes (A) an acid functional group-containing (meth)acrylic polymer having a glass transition temperature of about 25° C. or lower, and (B) an acid or base functional group-containing (meth)acrylic polymer having a glass transition temperature of about 50° C. or higher, the mixing ratio of the component (A) being larger than the mixing ratio of the component (B), and the adhesive film including an adhesive layer with a crosslinked structure derived from a metal coordination bond crosslinking agent and can be stretched to an area magnification of 4 times or more

The present disclosure relates to a film pasting assembly which comprises a base film provided with an annular first adhesive layer and a second adhesive layer, a first release film comprising a first annular portion and a first handle portion for arranging on the first adhesive layer, and a second release film comprising a second annular portion and a second handle portion for arranging on the second adhesive layer. The inner circumference of the first annular portion is equal to the outer circumference of the second annular portion. The first release film and the second release film may be torn apart respectively for product pasting. The success rate, efficiency of product assembly and yield of products may be improved. The first release film and the second release film may be processed by a same raw material for cost saving.

An electrically conductive bonding tape includes a conductive self-supporting first layer conductive in each of three mutually orthogonal directions and including conductive opposing first and second major surfaces, an conductive second layer coated on the first major surface of the self-supporting first layer and having at least 60% by weight of nickel, the second layer having an exposed major surface facing away from the first major surface of the self-supporting first layer and exposing at least some of the nickel in the second layer, and a conductive adhesive third layer bonded to the second major surface of the self-supporting first layer opposite the second layer. The adhesive third layer is conductive in at least one of the three mutually orthogonal directions and includes a plurality of conductive elements dispersed in an insulative material, at least some of the conductive elements physically contacting the self-supporting first layer.

Described is a mono-axially oriented polyolefin film including a core or base layer containing a plurality of voids formed by a cavitating agent, wherein the film is oriented at least 4 times in the machine direction, and exhibits excellent tear resistance in the transverse direction.

A self-adhesive multi-layer item comprising: 1) a dorsal support DO having a top face SI1 and a bottom face SI2, 2) at least one layer of silicone release coating RC applied to the top face SI1 of the dorsal support DO and which is prepared by irradiation of a curable silicone composition C not containing any solvent and comprising, as constituents: a) at least one functionalized organopolysiloxane A b) an effective amount of at least one type I photoinitiator P of the family of acylphosphine oxide derivatives of formula (III) 3) at least one adhesive PSA, preferably at least one pressure-sensitive adhesive PSA, applied on the layer of silicone release coating, 4) a frontal support FR applied on the adhesive PSA of the component 3), and 5) optionally at least one layer of silicone release coating RC applied on the bottom face SI2 of the dorsal support DO and which is prepared by application and irradiation of said curable silicone composition C, and on this same layer, there is at least one adhesive PSA, preferably at least one pressure-sensitive adhesive PSA.

A multilayer adhesive sheet, an optical member including the same, and a display apparatus including the same are provided. A multilayer adhesive sheet includes: a base layer; a first adhesive layer stacked on a surface of the base layer; and a second adhesive layer stacked on another surface of the base layer, and the base layer includes a polyurethane-based film manufactured by solution casting and has a storage modulus of 700 MPa to 1,500 MPa at −20° C. and a storage modulus of 10 MPa to 100 MPa at 85° C.

A shield that is attachable to a touch sensitive screen is disclosed. The shield may be attached to the touch sensitive screen only at its outer peripheral portion. An air gap is enclosed between the shield and the touch sensitive screen to form a planar air bearing. The shield preferably does not touch the active area of the touch sensitive screen when the user is not touching the shield but only viewing the touch sensitive screen through the shield. This mitigates unwanted optical artifacts such as trapped air bubbles, Newton rings and chromatic interference while maintaining the sensitivity of the touch sensitive screen.

A tamper evident label is provided. The tamper evident label broadly includes a base ply of pressure-sensitive material and a top ply of pressure-sensitive material. The base ply and the top ply are laminated together to form the tamper evident label The base ply includes a first portion and a second portion. The second portion of the base ply includes internal cuts and deadened adhesive. The top ply includes a tab portion defined by tab cuts. The tab portion of the top ply and the region between the internal cuts of the base ply are configured to be removed from the tamper evident label to create visual evidence of tampering. Further, a method of constructing a tamper evident label and a method of using a tamper evident label are provided.
