    • Disclosed is a method for the cathodic electrocoating of a tin-coated steel sheet in a treatment solution that does not contain any Cr compound, F or nitrite nitrogen. In the method, a tin oxide layer that is not subjected to a cathodic electrocoating treatment yet and is arranged on a tin-coated steel sheet is thinned to a specified thickness or less by a cathodic electrocoating treatment in an aqueous solution containing sodium carbonate or sodium hydrogen carbonate or a aqueous sulfuric acid solution immersion treatment, and the tin oxide layer is subjected to a cathodic electrocoating treatment in an aqueous solution of an alkaline metal sulfate containing a zirconium compound having a specified composition. In this manner, a coating film is formed on the tin oxide layer at a specific adhered amount in terms of Zr content. Also disclosed are: a process for producing a chromium-free steel sheet for a container material, which has excellent adhesion to an organic resin film and excellent iron elution resistance after dent impact; and a steel sheet for a container material, which is produced by the process.

    • The present invention relates to a viscoelastic resin composition for a vibration damping material and a vibration damping material using the same. The viscoelastic resin composition includes as its main components: Low Tg resin (A) with a glass transition temperature of -60.degree. C. to 0.degree. C. and a number average molecular weight of 5000 to 50000, the Low Tg resin (A) being a polyester containing an acid component having 50 to 90 mol % of aromatic dicarboxylic acid and 10 to 50 mol % of dimer acid, and a glycol component having at least 30 mol % of glycol with an alkyl group as its side chain and the glycol having at least four carbon atoms; and High Tg resin (B) which is at least one selected from the group consisting of amorphous polyester resins, phenoxy resins, and epoxy resins, the epoxy resins having a number average molecular weight of at least 1000, the respective resins having a glass transition temperature in the range of 0.degree. C. to 80.degree. C.; wherein the weight ratio between the Low Tg resin (A) and the High Tg resin (B) is in the range of 90:10 to 30:70. This viscoelastic resin composition is used for a resin layer of an attachable vibration damping material and a sandwich type vibration damping material.
