A core-sheath filament having a non-tacky sheath and a hot-melt processable adhesive core, the sheath exhibiting a melt flow index of less than 15 grams per 10 minutes, is provided. Methods of making the core-sheath filament and methods of using the core-sheath filament to print a hot-melt processable adhesive onto a primer-treated substrate surface to provide a structural bond are described.

Core-sheath filaments and methods of printing an adhesive

The present invention is an assembly layer for a flexible device. The assembly layer is derived from precursors that include about 0 to about 50 wt % C-Calkyl(meth)acrylate, about 40 to about 99 wt % C-C(meth)acrylate, about 0 to about 30 wt % hydroxyl (meth)acrylate, about 0 to about 10 wt % of a non-hydroxy functional polar monomer, and about 0 to about 5 wt % crosslinker.

Low dielectric optically clear adhesives for flexible electronic display

Wet-on-wet coating processes are provided to produce multilayer articles. First and second coating materials are sequentially applied on to a structured substrate surface to form a skin layer directly over the structured substrate surface and a bulk layer over the skin layer. The conformability of the skin layer can be adjusted to provide desired surface and bulk properties.

Multilayer articles via wet-on-wet processing

A core-sheath filament including a crosslinkable adhesive core that can be cured using ultraviolet or visible light radiation. These crosslinkable adhesive core compositions can provide very high bond strength and are capable of replacing traditional mechanical fasteners in many industrial applications. Core-sheath filaments including such crosslinkable compositions, crosslinked compositions, articles containing these compositions, and methods of making the articles are provided. The crosslinkable compositions contain pendant aromatic ketone groups or pendant (meth)acryloyl groups that, upon exposure to ultraviolet radiation, result in the formation of crosslinks within the polymeric material. The crosslinked compositions can function as pressure-sensitive adhesives.

Pressure-sensitive adhesive compositions are described comprising polymerized units of (meth)acrylate monomer. Also described are articles comprising such pressure-sensitive adhesive composition.

Adhesives comprising polymerized units of secondary hexyl (meth)acrylates

A curable mixture, a partially cured composition, a cured composition, an article containing either the partially cured composition or the cured composition, and a method of bonding two substrates are provided. The partially cured composition functions as a pressure-sensitive adhesive while the cured composition functions as a structural or semi-structural adhesive. The curable mixture can be applied to a first substrate by printing or dispensing, if desired.

Printable curable mixtures and cured compositions

Curable adhesive compositions are provided that can be cured using ultraviolet or visible light radiation. These curable adhesive compositions, which contain a curable (meth)acrylate copolymer, have a creep compliance that is less than 5(10) inverse Pascals at 25&#xb0; C., a creep compliance that is greater than 1(10) inverse Pascals at 70&#xb0; C., and a shear storage modulus greater than 40 kiloPascals when measured at 25&#xb0; C. at a frequency of 1 radian/second.

Curable and cured adhesive compositions

Modified adhesive layers are prepared by contacting an adhesive layer to a modified microstructured release liner. The modified release liner has a release layer surface with a set of microstructured depressions and a discontinuous pattern of ink material located on the surface of the release layer. A portion of the discontinuous pattern of ink material overlaps with and is located within some of the depressions. The ink material comprises a non-adhesive but adhesively transferrable material, or an adhesive material. Upon removal of the adhesive from the release liner, the ink material transfers to the adhesive surface.

Microstructured release liners for selective transfer of ink to film

The present invention is an assembly layer for a flexible device. The assembly layer is derived from precursors that include about 0 to about 50 wt % C-Calkyl(meth)acrylate, about 40 to about 99 wt % C-C(meth)acrylate, about 0 to about 30 wt % hydroxyl(meth)acrylate, about 0 to about 10 wt % of a non-hydroxy functional polar monomer, and about 0 to about 5 wt % crosslinker.

An adhesive article comprising first and second tacky latent adhesive layers disposed on respective first and second opposed major surfaces of a substrate. Each of the first and second tacky latent adhesive layers independently comprises at least one polymerizable component, and a redox initiator system comprising a transition metal complex that participates in a redox cycle, an oxidizing agent, and a blocked reducing agent represented by the formula ((I). Each of Rand Rare independently H, an alkyl, an aryl, or RPhoto5 with the proviso that at least one of R1 and Ris RPhoto. Rrepresents a photoremovable group. Each of Rand Rindependently represents H, an alkyl group, or an aryl group comprising a monovalent ester, ether, urethane, or carbonate group.

The present invention is an assembly layer for a flexible device. Within a temperature range of between about &#x2212;30&#xb0; C. to about 90&#xb0; C., the assembly layer has a shear storage modulus at a frequency of 1 Hz that does not exceed about 2 MPa, a shear creep compliance (J) of at least about 6&#xd7;10/Pa measured at 5 seconds with an applied shear stress between about 50 kPa and about 500 kPa, and a strain recovery of at least about 50% at at least one point of applied shear stress within the range of about 5 kPa to about 500 kPa within about 1 minute after removing the applied shear stress. The assembly layer includes at least one of a polyisoprene, a polybutadiene, an olefin block copolymer, a polyisobutylene, and high alkyl polyolefin.

Optically clear adhesive compositions contain an elastomeric polymer and a low molecular weight polymeric additive. The elastomeric polymer and the low molecular weight polymeric additive form an acid-base interaction. The refractive index of the adhesive composition is higher than the refractive index of the elastomeric polymer. The adhesive composition may also contain additional domains of liquids, polymers, additives or particles that have a higher refractive index than the elastomeric polymer.
