In order to overcome the problem of poor performance of waterborne coatings on polycarbonate（PC）plastics. Methyl methacrylate（MMA），styrene（St）and butyl acrylate（BA） were used as the main monomer，itaconic acid as a functional monomer，the introduction of a long-chain alkyl monomer lauryl methacrylate（LMA） and acetoacetoxyethyl methacrylate（AAEM）/polyether amine were cross-linking system，which prepared a self-linked acrylic latex. The effects of functional monomers，itaconic acid，LMA and AAEM/polyether amine on theperformance of acrylic latex and coating film were discussed. The experimental results showed that whenthe itaconic acid was 3. 0% of the total monomers，LMA 4. 5%，AAEM 9. 0%，and AAEM/polyether amine molar ratio was 2∶1，the prepared single-group water-based acrylic coatings presented excellent adhesion，ethanol-resistant and cooking-resistant on the PC plastic.
