- the polymer (A) used in the present invention is a copolymer which contains (a) styrene, and (b) a vinyl compound with carboxyl groups that is copolymerizable with styrene, as essential monomers.
- the abovementioned component (b) is a vinyl compound with carboxyl groups that is copolymerizable with styrene; suitable examples of such compounds include, but are not necessarily limited to, acrylic acid, methacrylic acid, maleic acid, maleic anhydride, fumaric acid, crotonic acid, itaconic acid, citraconic acid and cinnamic acid, and the like.

- (a)/(b) (weight ratio) is in the range of 1/9 to 9/1, preferably in the range of 2/8 to 8/2, and even more preferably in the range of 5/5 to 8/2.
- the workability of the coating film deteriorates; specifically, the hardness of the coating film is insufficient so that the coating film is susceptible to damage during press molding.
- the proportion of (a) + (b) in the polymer (A), i. e., the proportion of the total amount of component (a) plus component (b) in the polymer (A), is 30 to 100 weight %, preferably 40 to 100 weight %, and even more preferably 50 to 100 weight %.
- copolymerizable compounds other than components (a) and (b) contained in the polymer (A) used in the present invention; examples of desirable compounds include, but are not necessarily limited to, aliphatic alcohol esters of acrylic acid, methacrylic acid, maleic acid, fumaric acid, crotonic acid and itaconic acid, etc., e.
- acrylonitrile, methacrylonitrile, vinyl acetate, acrylamide and diacetoneacrylamide, etc. may also be used.
- ordinary methods used to polymerize vinyl compounds e. g., emulsion polymerization, suspension polymerization or solution polymerization methods, are desirable.
- a polymer with a glass transition temperature of 75 °C or greater, preferably 80°C or greater is suitable for use.
- the temperature of the surface of the material during press molding is ordinarily around 80 °C. Consequently, if the glass transition temperature of the resin in the coating film is too low, the coating film may be damaged during press molding. Accordingly, it is desirable that the glass transition temperature of the resin in the coating film be 75 °C or greater.
- substances which can be used as the lubricating agent (B) used in the present invention include, but are not necessarily limited to, paraffin wax, paraffin wax derivatives, microcrystalline wax, microcrystalline wax derivatives, polyethylene wax, polypropylene wax, candelilla wax, carnauba wax, rice wax, Japan wax, hohoba wax, beeswax, lanolin, spermaceti, montan wax, montan wax derivatives, ozocerite, ceresin, petrolatum, hardened castor oil, hardened castor oil derivatives, stearic acid amide and anhydrous phthalic acid amide, etc.

- the ratio of (B) to (A) + (B) is 2 to 30 weight %, preferably 3 to 25 weight %, and even more preferably 5 to 20 weight %.
- the ratio of the solid content of (B) to the total solid content of (A) + (B) is less than 2 weight %, the effect of the lubricating agent during press molding is insufficient.
- this ratio exceeds 30 weight %, the coating film stripping characteristics deteriorate since the lubricating agent is insoluble in water. Accordingly, such a high ratio is undesirable.
- the concentration of the solid content be in the range of 5 to 50 weight %, and a concentration in the range of 5 to 40 weight % is even more desirable.
- the concentration of the solid content is less than 5 weight %, the drying time is prolonged when a coating film is formed by applying the agent to the surface of the metal material. Accordingly, such a small concentration is undesirable.
- the concentration of the solid content exceeds 50 weight %, the viscosity of the metal surface treatment agent itself is increased, so that there is a danger that handling of the agent will be adversely affected.
- Surfactants known as wettability-improving agents, which are used to form a uniform coating film on the coated surface, conductive substances that are used to improve weldability, and coloring pigments used to improve design properties, etc., may also be contained in the metal surface treatment agent of the present invention as optional components.
- coating film stripping characteristics are a performance value that is necessary in cases where the metal material is used in applications requiring special features of the material (e. g., external appearance, vividness) or treatability in after-processes (e. g., phosphate formation treatments, alumite treatments), etc. In such cases, it is necessary that it be possible to strip the coating film by means of a treatment such as alkali degreasing, etc.
- the coating film can be stripped by means of alkali degreasing, and the like; however, the moisture resistance is insufficient, and the coating film becomes tacky as a result of being exposed to moisture in the air during the period between the application of the coating to the metal material and the molding process, so that there is a danger of blocking of the metal plates. As result, the metal plates must be stored under strict moisture control.
- stripping of the coating film can be accomplished by alkali degreasing, and the moisture resistance is improved. Consequently, there is no need for strict moisture control during the storage period between application of the coating to the metal material and the molding process.
- metal materials on which a coating film is formed using the surface treatment agent of the present invention are superior in terms of workability to metal materials on which a coating film is formed using a conventional surface treatment agent.
- metal materials treated with the metal surface treatment agent of the present invention include, but are not necessarily limited to, galvanized steel plates (electro-galvanized steel plates, melt-galvanized steel plates, alloyed melt- galvanized steel plates, galvanized steel plates containing 5% aluminum, galvanized steel plates containing 55% aluminum, vacuum deposition type
- the surface treatment agent of the present invention is applied the above mentioned metal material at a temperature of 10 to 40°C.
- the coating to method used may be a roll coater method, dipping method or electrostatic coating method, and the like.
- drying is performed with the temperature reached by the plates set at 50 to 180°C, preferably 60 to 160°C, and even more preferably 60 to 140°C.
- a coating film with superior coating film stripping characteristics can be formed on the surfaces of metal materials, and metal materials on which such a coating film is formed are superior in terms of press molding characteristics.
- the above mentioned temperature reached by the plates during drying is less than 50 °C, the coating film is sticky; accordingly, such a low temperature is undesirable.
- the temperature reached by the plates exceeds 180 °C, the cost involved in drying is increased so that such a process is uneconomical.
- the aforementioned surface treatment agent is applied and dried so that the amount of adhering coating film following drying is 0.1 to 5 g/m 2 .
- This amount of adhering coating film is preferably 0.2 to 4 g/m 2 , and is even more preferably 0.3 to 3 g/m 2 .
- this amount exceeds 5 g/m 2 , the effect on the press molding characteristics becomes saturated; accordingly, such a large amount is uneconomical.

- test samples were cut to a size of 70 mm x 150 mm, and were subjected to a degreasing treatment using Fine Cleaner 4336 (registered trademark, manufactured by Nihon Parkerizing Co., Ltd.), a silicate type alkali degreasing agent.
- Fine Cleaner 4336 registered trademark, manufactured by Nihon Parkerizing Co., Ltd.
- silicate type alkali degreasing agent a silicate type alkali degreasing agent.
- the test samples were subjected to a spray treatment for 2 minutes at a degreasing agent concentration of 20 g/L and a temperature of 60 °C, and were then washed with tap water. Following washing, the amount of surface carbon on the test samples was measured using a LECO (surface carbon analyzer), and the degree of coating film stripping was calculated using the formula shown below. An evaluation was then performed using the criteria shown below. Furthermore, "before degreasing", "after degreasing” and “untreated plates” in the
- ⁇ degree of coating film stripping is 80% or greater, but less than 95% x: degree of coating film stripping is less than 80%
- a coating film which is superior in terms of at least one of moisture resistance and coating film stripping characteristics can be formed on the surfaces of metal materials by applying the metal surface treatment agent of the present invention to the surfaces of such metal materials and drying the applied agent.
- the metal materials on which such coating films are formed are superior in terms of press molding characteristics. Furthermore, since the coating films formed on the surfaces of the metal materials are superior in terms of moisture resistance, no blocking occurs during the storage of the metal materials up to the time of press molding, even if the humidity is not strictly controlled.
- the metal surface treatment agent of the present invention brings out the special features of materials such as external appearance and vivid color, etc., and can be suitably utilized in the treatment of metal materials that require after-process treatments such as phosphate formation treatments or alumite treatments, etc.
