Removable protective film on a surface comprises a polymer containing at least two different polymers containing ethene, where the film is bounded with oxygen bonded carbon

摘要

Removable protective film (A) on a surface comprises at least a polymer (70 wt.%), based on the total quantity of all the components of the layer, containing at least two different polymers containing ethene (65 wt.%), where (A) is bounded with oxygen bonded carbon and the oxygen content of (A) increases with the increase in the distance to the surface. An independent claim is included for a method for applying (A) on a surface comprising treating the surface with n aqueous formulation (F i) of polymers (where n is >= 2 and i is 1 to n) comprising at least one ethene (65 wt.%) exhibiting oxygen bonded carbon; where the oxygen is optionally bonded to either polymer or to additional components of the formulation and the content of the oxygen bound to carbon in F iincreases with the increase in i.
