PROBLEM TO BE SOLVED: To obtain a binder formulation based on an aqueous polymer dispersion which assures uniform film formation without addition of a coalescing agent and forms a coating film of low adhesion and high blocking resistance. SOLUTION: The binder formulation has a minimum film-forming temperature of 10 deg.C or less, contains at least one anionic emulsifying agent and at least one nonionic emulsifying agent, and further contains at least one binder polymer in the form of an aqueous dispersion, the binder polymer comprising monomers of A1, A2, A3, B, C, D and E, where the monomer A1 is a vinyl aromatic monomer, A2 is a 1-4C methacrylate, A3 is acrylnitrile or methacrylonitrile, the monomer B is one kind selected from 1-18C alkyl acrylate and 5-18C alkyl methacrylates, C is methacrylic acid, D is one kind selected from 3-6C monoethylenically unsaturated monocarboxylic amides and 1-4C hydroxyalkyl esters and E is ethylene glycole diacrylate, or the like. |
