The present invention relates to a water redispersible polymer powder (RDP) which comprises a co-dried admixture of a water-insoluble film forming polymer, a colloidal stabilizer and rubber particles. The presence of rubber within the RDP does not significantly affect redispersibility and may, when incorporated into hydraulically-binding compositions, provide an improvement in the physical properties of the resultant hydraulically bound composition.

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.
