摘要： The invention provides a first water-based fluorine-containing paint including a water-based emulsion containing a fluorine-containing copolymer dispersed therein, and 1-50 parts by weight of a hardener per 100 parts by weight of the copolymer. The copolymer is prepared by copolymerizing 30-65 mol % of a fluoroolefin, 14-69 mol % of a copolymerizable vinyl-containing compound, and 1-30 mol % of a hydroxyl-containing compound and/or a polymerizable carboxyl-containing compound. The hardener is prepared by mixing 1 part by weight of a self-emulsifiable polyisocyanate with 0.01-1 part by weight of a compound containing in the molecule an oxyethylene unit and an alkoxysilyl group. When mixed with the emulsion, the hardener becomes well dispersed therein. The invention further provides a second water-based fluorine-containing paint including a water-based emulsion containing a fluorine-containing copolymer dispersed therein, and a hardener which is a compound containing in the molecule at least two hydrazino groups. The fluorine-containing copolymer is prepared by emulsion polymerization of 30-65 mol % of a fluoroolefin, 0.1-20 mol % of a polymerizable unsaturated carboxylic acid, 1-30 mol % of a polymerizable acetoacetylallyl compound, and 20-65 mol % of one of a vinyl ester and a vinyl ether. The second paint does not cure at ambient temperature, even after the hardener has been added thereto, and thus is usable as a one-package paint.

摘要： The invention relates to a coated granular fertilizer having a film covering fertilizer granules. This film comprises a polyurethane resin prepared by a method comprising the steps of (a) reacting an aromatic polyisocyanate with a first polyol component (i.e., castor oil or a castor oil derivative), thereby to obtain a prepolymer having terminal isocyanate groups in the molecule; and (b) reacting the prepolymer with a second polyol component (i.e., castor oil or a castor oil derivative) and a third polyol component which is an amine having at least two hydroxyl groups in the molecule, thereby to cure the prepolymer and thus to prepare the polyurethane resin. The invention relates to another coated granular fertilizer having a film covering fertilizer granules. This film comprises a urethane resin and aqueous-fluid-absorbing particles having a particle diameter of from 1 to 200 &mgr;m. This urethane resin may be the above polyurethane resin. This coated granular fertilizer can be produced by a method comprising the steps of (a) applying an aromatic polyisocyanate, a polyol component (i.e., castor oil or a castor oil derivative), an amine, and the aqueous-fluid-absorbing particles, at the same time or separately in no special order, while the fertilizer granules are kept fluidized or rolled, thereby to form a precursory film on the fertilizer granules; and (b) curing the precursory film into the film. Each coated granular fertilizer is substantially superior in regulation of the release of plant nutrient elements therefrom.

摘要： The present invention relates to a water-based fluorine-containing emulsion. This emulsion contains a fluorine-containing copolymer in a disperse phase thereof This copolymer is prepared by copolymerizing: (A) a fluoroolefin, (B) an organosilicon compound containing an olefinic unsaturated bond and an alkoxysilyl group, (C) an unsaturated carboxylic acid represented by a general formula of CH.sub.2 .dbd.CH--(CH.sub.2).sub.n --COOH where n is an integer of from 3 to 15, and (D) at least one other copolymerizable monomer. A paint prepared from the emulsion is superior in storage stability and mechanical stability, although this paint belongs to a one-package paint. A coated film formed by applying the paint is superior in water resistance in its early stages, stain resistance, and weather resistance.
