    Abstract: The invention relates to layer systems comprising (1) a substrate (S), (2) a scratch-resistant layer (K) obtained by at least partial hardening of a coating agent containing a polycondensate produced according to a sol-gel method and based on at least one silane, and (3) a covering layer (D) obtained by at least partial hardening of a coating agent obtained by common hydrolysis of (a) a compound of general formula I M(R')m (I) wherein M represents an element or a compound selected from the group consisting of Si, Ti, Zr, Sn, Ce, Al, B, VO, In and Zn, R' represents a hydrolysable radical, and m represents a whole number between 2 and 4, and (b) a compound of general formula (II) RbSiR'a, (II) wherein the radicals R' and R are the same or different, R' is defined as above, R represents an alkyl group, an alkenyl group, an aryl group or a hydrocarbon group having at least one halogen group, an epoxy group, a glycidyloxy group, an amino group, a mercapto group, a methacryloxy group or a cyano group, and a and b independently represent values between 1 and 3, the sum of a and b being equal to four. Said layer systems are characterised by an outstanding scratch resistance and abrasion resistance.

    Abstract: A cap for closing a container comprises a vapour permeable body and carries a coating of a relatively vapour impermeable material which is applied to the cap as a liquid and then cured to form a solid. The coating is permanently adhered to the cap body usually on the inside and contains a polymer which acts as a barrier usually to oxygen at least, and is preferably a vinyl chloride/vinylidene chloride copolymer or polyvinylidene chloride. Methods of making the coated caps are also disclosed.
