摘要：
A copolymer useful for magnetic paints is provided which is composed of (1) at least 60% by weight of vinyl chloride units, (2) 0.1 to 4.0% by weight, as a sulfur- or phosphorus-containing strong acid group, of strong acid group-containing monomer units (3) at least 0.1% by weight, as the hydroxyl groups, of units of a monomer which gives a side chain represented by the formula --X--OH wherein X is an organic group, and (4) 0 to 20% by weight of units of another monomer.
