An electronic device, a method and apparatus for producing an electronic device, and a composition therefor are disclosed. An adhesive material is applied in a first pattern on a surface of a receiver substrate. A carrier having a metal foil disposed thereon is brought into contact with the first substrate such that a portion of the metal foil contacts the adhesive material. The adhesive material includes a first polymer, a second polymer, and a conductive carbon black dispersion, and is activated using at least one of mechanical pressure and heat while the portion of the metal foil is in contact with the adhesive material. The first substrate and the second substrate are separated, whereby the portion of the metal foil is transferred to the first substrate. The adhesive is electrically conductive to maximize the possibility of maintaining electrical connectivity even when there is a break in the metal foil.

This invention relates to a process for the preparation of a polar-functionalized resin composition comprising the steps of (A) contacting a polymer backbone with a reactive moiety to produce a polar-functionalized resin composition wherein the polymer backbone is derived from a feed comprising less than or equal to about 35 wt % components derived from piperylene; less than or equal to about 10 wt % components derived from amylene; less than or equal to about 10 wt % components derived from isoprene; less than or equal to about 55 wt % unreactive paraffins; and C9 homopolymer or copolymer resins, in the presence of a Friedel-Crafts or Lewis acid catalyst; and (B) recovering a polar-functionalized resin composition.

The present disclosure is directed to a two-component bonding agent composition and a process for applying a layer of the bonding agent composition to substrate layers to make laminates.

An acrylic emulsion pressure sensitive adhesive composition is provided. The acrylic emulsion pressure sensitive adhesive composition, due to pH-dependent properties, exhibits stable adhesion when attached to an adherend, but when it needs to be removed, it can be easily removed without residue using an alkaline solution. Thus, if the acrylic emulsion pressure sensitive adhesive composition is used as a pressure sensitive adhesive for a label of a plastic packaging article, the label can be easily removed during a recycling process, thus improving recycling efficiency.
