Definitions

  • the object of the present invention is precisely to remedy this drawback by reducing the activity of the bath, that is to say the reaction kinetics.
  • titanium is dissolved in the development bath at a rate of 4 to 7 g / l.
  • the revelation operation is carried out in a bath whose temperature is between 20 ° and 30 ° C for an immersion time between 25 and 50s.
