Abstract
A vinylidene fluoride copolymer comprising 50 to 90% by mole of units having the formula (I): EQU --CH.sub.2 --CF.sub.2 -- (I) 1 to 30% by mole of units having the formula (II): ##STR1## 1 to 30% by mole of units having the formula (III): ##STR2## 1 to 30% by mole of units having the formula (IV): ##STR3## and a composition comprising the copolymer as the main component. Since the copolymer is excellent in solvent solubility, it can be dissolved in a widely used solvent for coatings and it is not required to treat the film at a high temperature after coating. Moreover, the obtained film is excellent in adhesion to a substrate, glossiness, weatherability, stain resistance and corrosion resistance.
