<p>An adhesive composition having natural rubber fine particles uniformly dispersed in a radiation hardenable compound. The adhesive composition, when subjected to radiation hardening to thereby form a pressure sensitive adhesive layer on a substrate, exhibits satisfactory bonding strength. The adhesive composition can be satisfactorily compounded with various fillers, and drying time after coating can be short. Both overall surface coating and pattern coating can be easily performed, and the adhesive composition can be applied to various substrates, realizing satisfactory bonding strength between the substrate and the pressure sensitive adhesive layer. The adhesive composition can be produced by mixing water base emulsion (31) containing natural rubber fine particles (30) with radiation hardenable compound (32) and heating the mixture under agitation so as to evaporate off water from the water base emulsion, with the result that the medium wherein natural rubber fine particles are dispersed is changed from water to the radiation hardenable compound.</p> |
