PURPOSE:To obtain the titled resin compsn. having excellent resistance to chemicals and water, flexibility and adhesion to supports, by using a butadiene polymer and a liquid polybutadiene having acryloyl or methacryloyl groups as components. CONSTITUTION:A resin compsn. contains a butadiene polymer (A) having a number-average MW of not lower than about 10,000 and at least one member (B) selected from among liquid polybutadiene having an average of 1.5 or move acryloyl groups and/or methacryloyl groups per molecule as components. Pref. the resin compsn. contains the components A and B in a weight ratio of A to B of 20-80:80-20. The compsn. can be easily crosslinked and cured by an actinic radiation such as electron beams. However, when the curing is carried out by intrared rays or ultraviolet rays, it is preferred to use a radical polymn. initiator.
