Abstract
213,016. Marks, E., C. R., (Columbia Graphophone Manufacturing Co.). Dec. 30, 1922. Plastic compositions containing fibres and resins.-A thermoplastic composition suitable for the manufacture of sound records consists of a filler, shellac, a resin of higher melting point such as copal, and a solvent common to the two resins, such as unsaturated fatty acids of the linoleic or olefinic groups. According to an example, 20-30 parts of shellac, 60-70 parts of a filler as baryta, china clay, &c. and 2 parts of colouring matter are mixed together. Seven parts of flock, 4 parts of copal, and 1 part of solvent as above are mixed and incorporated by heat (about 265‹ F.) until the flock is impregnated by the resin. The second mixture may be added to the first while in a plastic state or it may be allowed to cool and grouncl before mixing.
