Zusammenfassung:	THE PRESENT INVENTION PROVIDES A CHROMIUM-FREE SURFACE TREATMENT LIQUID WHICH ENABLES FORMING, ON A METAL MATERIAL SURFACE, A FILM EXCELLENT IN CORROSION RESISTANCE AT BENT PORTIONS OF A STEEL SHEET, SOLVENT RESISTANCE, COATING PROPERTIES AFTER ALKALINE DEGREASING, AND SWEAT RESISTANCE. THE SURFACE TREATMENT LIQUID CONTAINS A RESIN COMPOUND HAVING A SPECIFIC BISPHENOL SKELETON, A CATIONIC URETHANE RESIN EMULSION, A SILANE COUPLING AGENT, AN ORGANIC TITANIUM CHELATE COMPOUND, A QUADRIVALENT VANADYL COMPOUND, A MOLYBDATE COMPOUND, A FLUORINE COMPOUND, AND WATER AT PREDETERMINED PROPORTIONS. THE PH OF THE SURFACE TREATMENT LIQUID IS IN THE RANGE OF 4 TO 5.
