ABSTRACT:
The object is to provide a powdered metal injection compacting composition adapted to give compacts free from deformation, cracking or blistering without being compromised in compactability or debinder characteristic and without the aid of a special jig.
This composition comprises a metal powder and an organic binder comprising (A) a crystalline resin having a melting point of not less than 150.degree. C., (B) an organic compound the weight loss on heating of which begins at a temperature below 150.degree. C. and (C) a composite acrylic resin, the composite acrylic resin mentioned above being a resin obtainable by dispersing a solution comprising the following components (C1).about.(C3) in an aqueous medium containing a dispersant and carrying out a suspension polymerization reaction:
