The essence of the method of production of neutralized latex, which is suitable for the production of water-reducible substrates, is 1) in an aqueous emulsion in the presence of free radicals at pH less than 3.5 polymerized with a monomer, which based on 100% of monomer a) 30 and 70% by weight of vinylaromatic monomers, b) 25 and 65% by weight of at least one alkyl acrylate monomer, c) 1 and 5% by weight of acrylic acid and d) 0, 4 and 3% by weight of methacrylic acid, in the presence of 0.2 and 0.4 phm of at least one sulfonic agent and 4 and 8 phm of at least one of the nonionic surfaces of the active agent with a hydrophilic-lipophilic balance nm 12 and 20 to form a latex, 2) the latex is neutralized with ammonia to a pH between 7 and 10.5 to form a neutralized latex. It consists of a flat wall and a varnish containing a neutralized latex produced as described above. |
