To provide an adhesive composition capable of forming an excellently uniform adhesive layer, and a sheet for carrying information having an excellently uniform adhesive layer.
The adhesive composition comprises natural rubber fine particles and a radiation-curable compound, where the natural rubber fine particles comprise 100 pts. mass of the natural rubber and 15-30 pts. mass of a copolymer of acrylic monomers graft-polymerized thereonto. The manufacturing method of the adhesive composition comprises a mixing step for mixing an aqueous emulsion containing the natural rubber fine particles comprising 100 pts. mass of the natural rubber and 15-30 pts. mass of the acrylic monomer graft-polymerized thereonto with a radiation-curable medium; and a step for removing water contained in the aqueous emulsion by vaporization under ventilation or reduced pressure while stirring the mixture to replace the medium where the natural rubber fine particles are dispersed from water to the radiation-curable medium. The sheet for carrying information comprises a substrate sheet and, formed thereon, a pressure-sensitive adhesive layer comprising a cured product of the adhesive composition.
