To provide a printing varnish composition which can form a coating film on a film to make its surface permanently antistatic without adding any antistatic agent to a film base and without any problem of antistatic bleed and is excellent in coating film properties such as water resistance and chemical resistance.

The printing varnish composition having an antistatic effect comprises a cationic thermoplastic resin (A) comprising 10 to 60 wt.% quaternary ammonium salt-containing unsaturated monomer (a) represented by formula (1), 5 to 40 wt.% hydroxyl-containing unsaturated monomer (b), and 5 to 85 wt.% other (meth)acrylic monomers (c) and a thermoplastic resin (B) comprising 5 to 40 wt.% hydroxyl-containing unsaturated monomer (b) and 60 to 95 wt.% other (meth)acrylic monomers (c) in an (A):(B) ratio of 10:90 to 85:15 by weight.
