To obtain a self-adhesive composition which yields a slight tackiness of the applied surface when applied onto a substrate, allows a high self-adhesion between the applied surfaces and exerts an excellent aging property and printing suitability.

This adhesive composition contains as basic components (1) a cationic resin composition which is obtained by polymerizing a polymerizable unsaturated monomer (B) in the presence of a water-dispersible acrylic polymer (A), wherein at least one of the above water-dispersible acrylic polymer (A) and a polymer generated by polymerizing the above polymerizable unsaturated monomer (B) is a cationic polymer, and (2) a fine particle having an average particle size of from 0.5 to 30 μm. The acrylic polymer (A) includes a copolymer of a monomer mixture containing at least one of a cationic monomer or a hydrophilic monomer The weight ratio (A/B) of the acrylic polymer (A) to the polymerizable unsaturated monomer (B) is, e.g. about from 20/80 to 80/20.
