Abstract: A lactone solvent swell composition and method of using the composition. The lactone swell composition is used to condition resinous material for etching to form a porous textured surface on the resinous material. The porous texture permits the deposition of a metal on the resinous material such that a high integrity bond is formed between the textured resinous material and the deposited metal. Such a bond between the metal and the resinous material prevents de-lamination of the metal and resin bond. The lactone solvent swell compositions also desmear resin material from substrates. The lactone solvent swell compositions may be employed to treat resinous material used in the manufacture of printed wiring boards. Metal may be deposited on the textured resinous material by electroless plating.

Abstract: A process for applying a decoration into the surface of an object by sublimation ink printing uses, as the ink support or transfer sheet, a heat shrink film imprinted with sublimation ink decoration. Another process for applying a decoration into the surface of an object by sublimation ink printing uses a conventional ink support or transfer sheet, and a heat shrink film overwrap. The film sheet may be seamed to form an enclosure with the sublimation ink decoration, if any, on the enclosure inner surface. The object to be decorated is positioned inside the film enclosure. If a conventional transfer sheet is used, the conventional transfer sheet is positioned to the object before the heat shrink film is overwrapped. Before the sublimation ink imprinting, the object may be pre-treated with a coating into which the decoration will be imprinted. The film enclosure is heated to shrink the film into conformity with the object surface.
