艶出し剤が一部再分散されるためである。BACKGROUND OF THE INVENTION Many floor polish compositions, which conventionally contain water-insoluble emulsion polymers, waxes and dispersants, can be removed by applying an aqueous alkaline medium. It is purposely designed to be removed in this way, so that if the user so wishes (especially when it becomes dirty or scratches after long-term use), it can easily remove previously applied polishes. It is something that can be done. This is because the floor polish composition is alkaline in nature and because of its alkalinity, the previously applied polish is partly redispersed.

It is known that Japanese Patent Publication No. 47-15597 and Japanese Patent Publication No. 49-1458 include a polyvalent metal compound in a polishing composition. However, the coating films obtained by these methods do not have oil resistance, and when organic solvents, oils, etc. adhere to them, they dissolve and lose, or become contaminated, so they have to be constantly repaired.

耐油性、耐水性及び耐候性をもつ艶出し用金属架橋性水
性組成物を提供することを目的とするものである。SUMMARY OF THE INVENTION It is an object of the present invention to provide a metal crosslinkable aqueous composition for polishing, which has oil resistance, water resistance and weather resistance which have not been found in the past.

属架橋性フッ素樹脂組成物を提供するものである。The present invention has been made to achieve the above object and has an acid value of 5 to 50 mg KO.
It is intended to provide a metal-crosslinkable fluororesin composition, which comprises a fluorine-containing polymer of H / g and a polyvalent metal compound capable of forming a metal crosslink as essential components.

れる。The fluorine-containing polymer of the present invention means, for example, a fluorine-containing polymer having a hydroxyl group obtained by copolymerizing a monomer having a hydroxyl group such as hydroxyalkyl vinyl ether among fluoroolefin copolymers. Examples thereof include those obtained by reacting a dibasic acid anhydride to introduce a carboxyl group (see JP-A-58-136605).

性が劣る。Unlike the usual polycarboxylic acid resin, such a fluorine-containing polymer is characterized in that it is easily dispersed in water in the low acid value region and is stable. In the present invention, the acid value is 5 to 50 mgKOH / g, preferably 7-40 mg KO
A fluoropolymer in the range of H / g is used as the aqueous composition. When the acid value is less than 5, it cannot be sufficiently dispersed in water and is unstable even if it can be dispersed. On the other hand, when the acid value exceeds 50 mgKOH / g, the water resistance of the coating formed is poor.

The polyvalent metal compound can be added to the composition in the form of oxides, hydroxides or basic salts, acid salts or neutral salts having a pronounced solubility in water such as at least 1% by weight. Beryllium, cadmium, copper, calcium, magnesium, zinc, zirconium, barium, strontium, aluminum, bismuth, antimony, lead, cobalt, iron, nickel or other polyvalent metals can be employed. As polyvalent metal compounds, ammonia and amine complexes of these metals are particularly useful.

Polyvalent metal complexes of organic acids soluble in the alkaline pH range can also be used. Anions such as acetate ion, dultamate ion, formate ion, carbonate ion, salicylate ion and glycolate ion are satisfied.
