The thickener of the top coat in the water-based luminescent paint of example 1 is respectively replaced by a TPU color paste thickener (thermoplastic polyurethane elastomer TPU, F813), a block high molecular polymer (styrene-isoprene-styrene block copolymer, F814) and a nonionic associative polyurethane (ethoxy polyurethane, F620), and the obtained paint is coated according to the coating preparation method of example 1, and the brightness test method is adopted to test the luminous intensity, and the result is shown in fig. 7. The coatings obtained from the above thickeners all showed less afterglow brightness after 20min of transfer into dark environment than the coating obtained from example 1 using the thickener according to the invention.
While the foregoing is directed to the preferred embodiment of the present invention, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention.
