    Invention Patent Descriptive Report for "METHOD FOR REDUCING ADHESION FORCES BETWEEN DU- 'RAS SURFACES AND DIRT THAT SUBSEQUENTLY OCCURS",. Field of the Invention The present invention relates to a method for reducing the adhesion forces between hard surfaces and soil occurring subsequently by treating the hard surfaces with a liquid composition comprising special copolymers A. Background of the Invention Generally, washing compositions , cleaning and liquid disinfectants are used to remove dirt from already soiled hard surfaces. However, due to the adhesion forces between hard surfaces and adhered dirt, the removal of dirt is often incomplete or requires treatment: - excessive such as rubbing or rubbing the hard surface, etc.
    Consequently, it is an object of the present invention to provide a method for reducing the adhesion forces between hard surfaces and dirt occurring subsequently.
    Surprisingly, it was concluded that this objective is solved by treating hard surfaces with a liquid composition comprising special copolymers A. Summary of the Invention So, the invention provides a method for reducing the adhesion forces between hard surfaces and dirt occurring subsequently characterized by the fact that the method comprises the step of treating hard surfaces with a liquid composition comprising one or more copolymers A comprising: (a1) 1 to 50% by weight of one or more of the structural repeating units of the formula (1) Wounds Ac de) (1)

    The copolymers that are used in the inventive method are called copolymers A.
    Copolymers A that can be used in the inventive method and their preparation are, for example, described in EP 1 11673 and EP1069142.

If copolymers A comprise one or more structural repeating units of formula (3) where X is H *, the degree of neutralization of one or more structural repeating units of formula (3) is preferably 90% or more.
    This means that X has a different meaning from H * in 90 mol% of one or more structural repeating units of formula (3). If copolymers A comprise one or more structural repeating units of formula (3) where X is H *, the degree of neutralization - of one or more structural repeating units of formula (3) is particularly | preferably preferably 95% or more and especially preferably 98% or more.

Detailed Description of the Invention In the first stage of the inventive method, hard surfaces are mixed with liquid compositions comprising copolymers A.
    The clamping occurs subsequently, that is, after the first stage of the inventive method, it adheres less strongly to the hard surface and thus can be removed more easily in the following cleaning steps providing a cleaning effect the next time.
    Without being limited to this theory, it is believed that copolymers A applied in the first stage of the inventive method create a protective layer on hard surfaces, which reduces the adhesion forces between hard surfaces and the dirt that subsequently occurs.
