Abstract: Dissolvable unit dose film constructs are made by providing a muco-adhesive composition including a muco-adhesive polymer matrix in which the muco-adhesive polymer matrix has a water-soluble polymer, water-dispersible polymer, water-swellable polymer, or combinations thereof and a liquid carrier. The method further includes drying the muco-adhesive composition to remove at least a portion of the liquid carrier, forming a muco-adhesive film substrate, forming a composition for an active layer, the composition including a polymer matrix in which the polymer matrix for the active layer composition includes a water-soluble polymer, water-dispersible polymer, water-swellable polymer, or combinations thereof, an active ingredient and a liquid carrier.

Abstract: A method is provided for photographic developing using a roll of photographic paper. A photographic image is formed on the paper, and the image-containing portion of the paper cut from the roll of paper. The improvement comprises the end of the roll of paper being initially maintained in place by means of a pressure sensitive adhesive tape comprised of a polyisobutylene-or polybutene-based pressure sensitive adhesive on a backing layer, with the tape being removed prior to the roll being used as a substrate for the photographic image. The combination of a roll of photographic paper whose free end is held in place by the pressure sensitive adhesive is also provided.

Abstract: A method of production of veneer assemblies is provided wherein a thermocurable adhesive is placed along the joint between adjacent veneer sheets and a core substrate and subjected to heat pressing to bond the veneer to the core substrate.
