Abstract

An adhesive useful in making composites includes two components A and B. Component A includes at least one polymer having a molecular weight (Mn) of at least 800 that has at least one functional group polymerizable by irradiation with 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. Component B includes 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.
