The invention relates to environmental-friendly laser glue needed by a laser ablation method for photogravure. The laser glue is anti-corrosion and can be removed easily and ablated by laser. The laser glue comprises the following components in percentage by weight: 5 to 40 percent of water-based resin, 0 to 10 percent of cross-linking degree controlling agent, 0.2 to 40 percent of laser absorbent, 0 to 5 percent of laser sensitizer, 2 to 10 percent of antifreeze, 0 to 10 percent of quick-drying agent, 0 to 5 percent of pH regulator, 0 to 1 percent of flatting agent, 0 to 1 percent of defoaming agent, 0 to 1 percent of preservative, 0 to 5 percent of thickening agent, 0 to 5 percent of dispersing agent and the balance of deionized water. The water-based laser glue has the advantages of no environmental pollution, no harm to human body and no combustion explosion. The laser glue can also be used for manufacturing precision dials, brass plates, crafts and the like by a corrosion method.
