Abstract: The invention relates to the polishing of silver-plated, in particular electro-plated silver. The feature of the invention is the provision of a formulation which in the dry, solid state has a high storage life and is free of any toxic components and therefore usable in the home in hotels and in like establishments. The formulation comprises in powdered form at least one silver generating component such as a silver salt or silver oxide and at least one reducing component for the salt or oxide. When water is added to this dry powdered composition to form a paste as needed, and the paste is used on a plated base metal or alloy for cleaning and/or restoration purposes, silver is both deposited and polished by the use of the composition. Different qualities of finish may be obtained depending upon whether the solid formulation also comprises in powdered form either one of the conventional relatively harsh abrasives such as rouge or a very mild agent such as one of the conventional fillers, e.g.

Abstract: A heat transfer comprising a temporary support and a label carried on the support. The label comprises a layer of a polyurethane resin system which includes a polyurethane obtained by reaction of a diphenyl isocyanate, a free glycol and a polyester either of the formula ##STR1## wherein R is an alkylene radical of 2 to 8 carbon atoms and R.sup.1 is an alkylene radical of 4 to 10 carbon atoms or of the formula ##STR2## wherein R.sup.11 is an alkylene radical of 4 to 8 carbon atoms. The polyurethane resin system further includes a cross-linking agent and a catalyst so that when the label is placed in contact with an article to be marked and subjected to heat and pressure, the resin system is converted to an inert insoluble and wear resistant form and a substantially permanent marking is produced on the article.
