The infrared-laser stealthy coating was prepared by the way of coating on the glass，natural drying and using chromium oxide coated aluminum composite particles （Al/Cr2O3）as filler，polycarbonate-based waterborne polyurethane as adhesive.Effects of adhesive，filler and the amount added into the coating on infrared emissivity and laser reflection of the coating are studied.Infrared emissivity at spectral range of 8~14 μm and laser reflection at spectral range of 10.6 μm were measured with infrared emissivity test instrument and tunable CO2 laser.The results show that the infrared emissivity of adhesive used in this coating is low compared with ordinary waterborne polyurethane.Infrared emissivity and reflected laser energy of the coating decrease with the increase of composite particles.Infrared emissivity is reduced to 0.688 and the energy reflected back is only 1% of the initial incident laser energy，when the composite particles added are 30%.The coating has better comprehensive properties and can meet the requirements of the IR-laser stealth.
