Abstract:
An adhesive composition comprising three components A, B and C:(a) component A being at least one polymer having a molecular weight (Mn) of at least 800 that has at least one functional group polymerizable by irradiation with ultraviolet (UV) light or with electron beams and has at least one functional group capable of reacting with a compound having at least one acidic hydrogen atom; (b) component B being at least one compound having a molecular weight (Mn) of from about 100 to about 8000 which has at least two functional groups polymerizable by irradiation with UV light or with electron beams; and (c) component C comprises at least one photoinitiator obtained by reacting a polyfunctional alcohol having two or more OH groups with a di- or triisocyanate and a photoinitiator having at least two isocyanate-reactive functional groups and which is capable of initiating the polymerization of olefinically unsaturated double bonds on exposure to UV radiation.
