Binding agents having barrier properties are provided which contain: a) a compound having at least one NCO group and at least one reactive functional group, which can be cured by radiation and which serves as component (A), and; b) a silicon-organic compound serving as component (B) with at least one NCO group and at least one functional group of formula (I): &#x2014;Si(Z)(X), in which Z represents C-Calkyl group, preferably C-Calkyl group; X represents &#x2014;NH; &#x2014;NH&#x2014;CO&#x2014;R; &#x2014;OOC&#x2014;R; &#x2014;O&#x2014;N&#x2550;C(R)or OR'; R represents a linear or branched, saturated or unsaturated C-Calkyl radical; R&#x2032; represents R, an oxyalkylene radical having up to 4 carbon atoms, a C-Ccycloalkyl radical; a C-Caryl radical or a C7-Caralkyl radical; and n equals 0, 1 or 2. The binding agent can be used as a radiation curable binding agent in coating agents, fillers, sealants or adhesives, for example in the preparation of laminated films having barrier properties.

Polyurethane prepolymers containing NCO (isocyanate) groups and having a low content of monomeric polyisocyanate, processes for their production and uses employing these prepolymers. The polyurethane prepolymers of the invention are produced from by a reaction employing monomeric polyisocyanates and polyols.

An adhesive containing a) a compound containing at least one vinyl ether group which has a molecular weight of more than 400 and b) a photoinitiator which initiates a polymerization of component A after exposure to light with a wavelength of 100 to 600 nm is useful for the production of a film laminate.

A low-monomer PU prepolymer containing free NCO groups which is obtained from polyhydric alcohols and diisocyanates differing in their reactivity and which is distinguished by the ratio of the NCO groups of the partly slower-reacting diisocyanate to the NCO groups of the faster-reacting diisocyanate. It is greater than 6:1. Nevertheless the prepolymer according to the invention cures more quickly than a known prepolymer predominantly containing fast-reacting NCO groups. In a preferred embodiment, TDI is used as the partly slower-reacting diisocyanate while MDI is used as the faster-reacting diisocyanate. The prepolymer is produced in two stages. The prepolymer according to the invention is suitable for bonding plastic articles, metals and paper, especially films. The accelerated absence of migration is particularly noticeable in this regard.
