PROBLEM TO BE SOLVED: To provide a surface-coating composition that can form surface- treating coating film having excellent gas barrier properties, transparency and such a grade of flexibility that does not damage of the physical properties of the coating treated body. SOLUTION: This surface-coating composition comprises (A) a polyethyleneimine bearing no Si(OR1) group (R1 may be the same or different, and represents H, a lower alkyl group or an acyl group), (B) a compound bearing functional groups reactive with the amino group in the polyethyleneimine in the molecule, (C) an organic silane and/or the hydrolyzate thereof and (D) a solvent that can dissolve (A) polyethyleneimine, (B) the compound reactive with the compound A and (C) an organic silane and/or the hydrolyzate and condensate of the organic silane. |
