    Abstract: The invention relates to a one-component aqueous spray adhesive and use thereof, and a product comprising the one-component aqueous spray adhesive. The one-component aqueous spray adhesive comprises an aqueous chloroprene dispersion, wherein the increase of the Shore A hardness of the formed adhesive film in 0 to 10 hours accounts for equal to or more than 90% of the increase of the Shore A hardness of the formed adhesive film in 0 to 1000 hours, wherein the increase of the respective Shore A hardness of the formed adhesive film is determined according to the method identified in the specification; a styrene-acrylate copolymer dispersion having a solid content of 15% by weight to 25% by weight, relative to the total weight of solids of the aqueous chloroprene dispersion; a polyol ester without hydroxyl groups in an amount of 0.9% by weight to 3.8% by weight, relative to the total weight of the aqueous spray adhesive; and an amino acid in an amount of 4% by weight to 15% by weight, relative to the total weight of the aqueous chloroprene dispersion; and optionally, a nanosized metal oxide and an auxiliary agent. The spray adhesive of the present invention shows short time to contact, long open time and good storage stability at room temperature.
