The invention relates to the technical field of a coat prescription, in particular to an aqueous medium coat prescription of a laser film material. According to weight percentage, the prescription comprises the following components: 10 to 20 percent of methyl methacrylate; 10 to 20 percent of ethyl acrylate; 30 to 40 percent of water; 20 to 30 percent of ethanol; 0.1 to 0.2 percent of dimethyl silicone polymer; and 0.1 to 0.3 percent of anion surface active agent. The medium coat prescription is the aqueous coat prescription; after being used, the dyne value on the surface of an aluminum layer is stable which can lead the UV glue layer of the laser film and the aluminum layer to achieve a compact effect; besides, the volatile organic compounds (VOC) in the product of the laser film can also achieve required standard; and therefore the aqueous medium coat prescription of the laser film material is an environmental friendly product.
