Abstract
A process for producing a film-forming material, which comprises graft-polymerizing a monomer having a radical polymerizable ethylenically unsaturated group in the presence of a radical initiator with a butadiene polymer of a low degree of polymerization having a number average molecular weight of 300 to 10,000, a butadiene copolymer of a low degree of polymerization containing not more than 50% by weight of a copolymer component, or a mixture of these, in the form of an aqueous solution, said butadiene polymer or copolymer in aqueous solution or aqueous dispersion containing 0.05 to 0.5 mole, per 100 g of the polymer, of a basic group of the general formula ##STR1## wherein R.sub.1 represents a hydrogen atom, a halogen atom or an organic group containing 1 to 8 carbon atoms; R.sub.2 and R.sub.3 are identical or different and represent an organic group containing 1 to 20 carbon atoms; R.sub.4 represents a hydrogen atom or an organic group containing 1 to 20 carbon atoms; and X represents a hydrogen atom or a bond, and when X is a bond, the carbon atom attached to R.sub.1 and the adjacent carbon atom to which hydrogen is attached may form a part of the main chain.
