ABSTRACT A catalytically active powder, its preparation, and a method for using the said powder for making insulating substrates activated to receive electrolessly deposited metal in a coherent metal layer are described. It is a plastic powder containing chemical compounds allowing that the acceleration of the catalyst is not carried out until the powder is melted down onto the substrate. The substrate need not be etched prior to the metallizing since the plastic melted down ensures a good adhesion between metal and plastics and between plastics and substrate. Furthermore, the colloidal nature of the catalyzing compounds has in a particular and especially durable manner been stabilized by the plastic powder. The use of the powder causes less risk to the environment since the catalyst may be transported as a dry powder, and since the etching of the substrate is avoided.
