Abstract: The present invention relates to a mold for a chemically curable composition including a first shell component, a second shell component and a honeycomb core interposed therebetween. The invention further relates to providing an essentially adiabatic environment for chemically cured compositions using the previously described mold.

Abstract: A wound roll suitable as a packaging material contains in order a release coating, a flexible polyester film, an adhesive, a flexible polymeric film support and a cold seal adhesive.

Abstract: A polymeric film comprising a polyester film substrate comprising 0.1% to 10% by weight, relative to the weight of the polyester, of at least one UV absorber, and a heat sealable layer, wherein the substrate is a multilayer film having an outer substrate layer and an inner substrate layer, the inner substrate layer comprising 1% to 40% by weight of UV absorber, relative to the amount of UV absorber present in the outer substrate layer. The film is particularly suitable for use as a protective layer on a metal sheet.

Abstract: A composite film is described which consists of a primary unfilled polyester layer and a secondary polyester layer containing from 1 to 8% by weight, based on the weight of the secondary polyester layer, of finely divided silica particles having a volume weighted mean particle size diameter D[4,3] of from 2.3 to 6.2 micrometers. The composite film is used in backlit displays such as illuminated signboards and provides uniform light transmission while maintaining the same strength of illumination at all points over the area of the display.

Abstract: A novel class of interpenetrating polymer networks which are dispersible in conventional coating solvents is disclosed. Such dispersions are useful in preparing protective and/or decorative film coatings and are particularly useful in photosensitive or imaging formulations such as photoresists, solder masks and the like. These polymer networks are comprised of at least two interpenetrating crosslinked polymers. At least one of the polymer networks is formed by polymerization in a solvent. In one embodiment of this invention, at least one polymer network is prepared from macromers to produce a polymer system having functionalized branch or graft linear segments. The solvent dispersible interpenetrating networks of this invention are particularly useful as binders in addition polymerizable photosensitive compositions containing crosslinking monomers such as solder masks. Upon exposure to actinic radiation and suitable thermal curing, solder mask coatings of such photosensitive compositions form multiple, e.g.
