ABSTRACT:
An organic fluorine compound represented by the general formula
R.sub.f -(X).sub.h -R-M
wherein R.sub.f is a group selected from the following (a) and (b); ##STR1## X denotes a linking group selected from --O--, --S--, and --COO--, h denotes 0 or 1, R is a hydrocarbon chain comprising a phenylene group having an alkylene group with a total carbon number of 10 or more, or the derivative thereof, or an aliphatic alkylene group of a carbon number of 10 or more, and M is a group selected from --OH, --COOH, --SH, and --CONH.sub.2.
The organic fluorine compound of the present invention greatly improves the dispersibility of magnetic powders in magnetic coating materials, has also an excellent rust prevention effect on metallic magnetic powders, and exhibits a marked dispersing effect even on fluorocarbon resin fine powders, which can be difficultly dispersed with conventional dispersing agents.
