Abstract
The present invention discloses a surface treated material of excellent adhesion for painting layer, corrosion resistance after painting and press formability, containing, in a Zn or Fe series plating layer, a (meth)acrylic polymer having repeating units of a (meth)acrylic acid derivative in which a compound having an epoxy group is added to a chemical formula represented by: ##STR1## where X represents --NH-- or --O--, A represents C.sub.n H.sub.2n, n is 0 or a positive integer, R represents --H or --CH.sub.3, and R.sub.1, R.sub.2 which may be identical or different with each other represents H or alkyl group.
