SURFACE TREATED MATERIALS OF EXCELLENT ADHESION FOR PAINTING LAYER, CORROSION RESISTANCE AFTER PAINTING, AND PRESS FORMABILITY, AS WELL AS A METHOD OF MANUFACTURING THEM

摘要

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: where X represents -NH- or -O-, A represents CnH2n, n is 0 or a positive integer, R represents -H or -CH3, and R1, R2 which may be identical or different with each other represents H or alkyl group.
