    Abstract: Securely bonded layers of electroless metals on bodies having a resinous surface are provided after first contacting the surface of the body with a highly active, easily controllable, readily disposable composition comprising water, permanganate ion and manganate ion, the molar ratio of manganate to permanganate being up to about 1.2 and the composition having a pH controlled in the range of 11 to 13. Resinous surfaces so treated are neutralized in a process including treatment with hydrazine in order to yield metallized resinous surfaces exhibiting superior peel strengths following electroless metal deposition.

    Abstract: Improved catalytic fillers result from the use of hydrazine to render reducible metal salts absorbed on filler material surfaces catalytic to the deposition of electroless metal. Use of such catalytic fillers in forming insulated articles in which holes are made lead to improved electroless metallization of the barrels of such holes.
