• Nail care products especially in the form of nail polishes, are among the most used decorative cosmetics. They usually contain a synthetic resin as a film former as well as inorganic or organic pigments or dyes.
• the nail polishes should have a high gloss, high hardness and good adhesion to substances containing keratin, such as fingernails, and should dry quickly at room temperature to form a non-sticky, uniform film. The high gloss and good adhesion should be maintained for as long as possible.
• the film-forming resins used must be soluble in water-acetone mixtures.
• the film-forming resins should be insoluble in water or water-alcohol mixtures so that the nail polish does not dissolve when it comes into contact with water or when handling common household chemicals.
• Nail varnishes with aqueous emulsion polymers are increasingly being used as binders.
• EP-0424112 describes nail polish formulations which contain an emulsion polymer with a core / shell structure as a binder.
• the outer shell polymer has a softening temperature that is lower than that of the inner shell polymer.
• the nail polish compositions described therein have inadequate adhesion to substrates containing keratin, e.g. B. on fingernails, show and quickly lose their shine after drying.
