Binder for aqueous gloss paints

摘要: The inventive vehicle, or binder, for water based gloss paints contains, dispersed in a aqueous phase, particles of multiphase emulsion polymer made up (a) core material having glass transition temperature exceeding 40° C. and (b) shell less than 70° at least 20 K. below that the material. have an average diameter 200 nm. composition includes with 4 percent by weight ethylenically unsaturated carboxylic acid more 80 one monomers from group consisting styrene alkyl esters acrylic and/or methacrylic acid. Paint coats produced this vehicle are distinguished high blocking point.
