Definitions

  • the invention relates to a method of providing a metal mirror on an article of which at least the surface on which the metal mirror is to be provided is manufactured from a synthetic resin, whereby the said surface is treated with tannic acid and provided with a metal mirror by means of an electroless metallization process.
  • the invention is based on the recognition gained by Applicants that a pretreatment with tannic acid in combination with an oxidising pretreatment step, has a more universal character and can be applied to the above-mentioned types of synthetic resin, in which after metallisation, a very adherent metal mirror is obtained.
  • the metal mirror also remains bonded to the synthetic resin surface after ageing tests, for example a cyclic moisture test.
  • a surface of polyethylene, polyvinyl chloride, polystyrene, polyethylene terephthalate, polyacrylate or polymethylmethacrylate is subjected to a corona discharge, is treated with tannic acid, and is provided with a metal mirror by means of an electroless metallization process.
  • a surface of polyvinyl chloride or polycarbonate is treated with chromic acid, then with tannic acid, and is provided with a metal mirror by means of an electroless metallization process.
  • the surface of a synthetic resin as recorded in column 1 of the Table below is subjected for a few seconds to a corona discharge by means of a HF generator having a sinusoidal alternating voltage of 12018 kV and a frequency of 20-40 kHz which is connected to an electrode placed above the surface of the synthetic resin.
  • the surface of the synthetic resin is then treated with an aqueous solution of tannic acid for at most one minute at a temperature of 25°C.
  • concentration of tannic acid in the solution is not restricted to narrow limits and may be chosen, by way of example, between 0.1 and 10 g of tannic acid per litre.
