Abstract

1403197 Metallizing particles BELL & HOWELL CO 7 Sept 1972 [30 Sept 1971] 41513/72 Heading C7F Particles of solid or liquid have applied thereto a composition comprising a metal compound capable of reduction to catalytically active sites for electroless plating and a binder comprising one or more polymers and/or polymer-formers and a solvent for said compound and binder so that a coating of compound and binder is formed thereon, and the coated particles are then electroless plated. The particles may be solid, e.g. glass beads, metal, inorganic compounds, minerals asbestos, wax, thermoplastic or thermosetting polymer, copolymer or inorganic compound/ polymer mixtures, of size 10-200Á or colloidal particles of size 0.001-10Á Said composition may contain 0.001-1 wt per cent of metal compound, e.g. a salt of Ag, Au, Ru, Rh, Pd, Os, Ir or Pt, a binder in wt. ratio binder: metal of 0.3 to 15: 1 which binder is an alkali metal silicate, aluminosilicate, phosphonitrile, polyborane, or an organic polymer (or polymer-former) or a natural product such as starch or gum; the solvent is organic (a list is given) and a binder/metal compound layer 20- 300 A thick is formed, and the particles separated, washed and dried, then conventionally electroless plated e.g. with Ni, Co, Cu, Ni-Fe, Ni- Co, or Ni-W-P for 5 sec-2min. at 25-65 C to thickness 0.01-5Á. Liquids may be encapsulated by forming a suspension thereof in a solution containing binder and metal compound as above so that the binder coats the liquid to give encapsulated sensitized particles, or ready-encapsulated liquids or solids may be treated as above.
