To make waterborne painting be applied into metal protection area, the mechanical, water resistant, and anti‐corrosion properties of the dried coating based on it should be improved effectively. Among various methods, self‐crosslinking the latex during its drying process is thought to be an effective way. For example, the latex with DAAM/ADH (diacetoneacrylamide/adipoyl hydrazide) as the self‐crosslinker has attracted a lot of attention due to its excellent stability and coating performance. In this study, a kind of reactable AIEgen was used and taken part in synthesizing the self‐crosslinkable acrylic latex. Based on Aggregation Induced Emission(AIE) phenomenon, it is easy to real‐time trace the preparation and curing process of the obtained latexes. At the same time, the influence of DAAM/ADH on the properties of the cured coating was studied in detail. In addition, as AIEgen is knitted onto the polymer chains via chemical bonds, external stimulus might interfere the coating's fluorescent property. Based on this phenomenon, the cured coating was studied and explored the feasibility to be applied into gas sensing area via its fluorescent property.
