Abstract:
A metal surface treatment agent comprising from 0.001 to 10% by weight of a polymerizable monomer containing a thiophenecarboxylic acid ester group therein and from 0.001 to 10% by weight of a polymerizable monomer containing a phosphoric acid ester group therein dissolved in an organic solvent:wherein said polymerizable monomer containing a thiophenecarboxylic acid ester group therein is at least one member selected from compounds represented by the following chemical formulae: ##STR4##wherein R.sub.1 is H or CH.sub.3 ; R.sub.2 is H, Cl, COOH, COCl, CONH.sub.2, or CN; and n is an integer of from 2 to 16; and whereinsaid polymerizable monomer containing a phosphoric acid ester group therein is at least one member selected from compounds represented by the following chemical formula: ##STR5##wherein R.sub.1 is H or CH.sub.3 ; ##STR6##and n is an integer of from 2 to 16.
