Claims7
A film-forming composition comprising a chlorinated polyalkyleneglycol binder produced by chlorinating a polyalkyleneglycol having a molecular weight of not less than 200 and selected from the group consisting of polyethyleneglycol, polypropyleneglycol and mixtures thereof in a solution of the polyalkyleneglycol in a chlorine-resistant solvent, to a chemically combined chlorine content of 50 to 75% by weight, based upon the weight of the produced chlorinated polyalkyleneglycol, wherein said polyalkyleneglycol binder is soluble in alcohols, aliphatic solvents and aromatic solvents.
