  • Patent number: 5021469
    Abstract: The inventive vehicle, or binder, for water based gloss paints contains, dispersed in a aqueous phase, particles of a multiphase emulsion polymer made up of(a) core material having a glass transition temperature exceeding 40.degree. C. and(b) a shell material having a glass transition temperature of less than 70.degree. C. and at least 20 K. below that of the core material.The particles have an average diameter of less than 200 nm. The composition of the shell material includes an emulsion polymer with at least 4 percent by weight of an ethylenically unsaturated carboxylic acid and more than 80 percent by weight of one or more monomers from the group consisting of styrene and alkyl esters of acrylic and/or methacrylic acid. Paint coats produced with this vehicle are distinguished by a high blocking point.
