Diazoresin (DR)‐based ultra‐thin films were fabricated on anodized aluminium plate (AAP) and investigated. The results show that the adsorption of DR on AAP surface is characteristic of Langmuir‐type and reaches saturation rapidly. The thickness of adsorbed monolayer films was determined with angle‐resolve X‐ray photoelectron spectrometry (ARXPS) to be 2.5–3.5 nm. It was confirmed that after UV‐irradiation the DR combines tightlywith the AAP surface via chemical bonding. As a result, the monolayer films exhibit excellent wear resistance and high stability towards solvents. Meanwhile the AAP surface nature becomes hydrophobic from original hydrophilic and accepts ink easily. In addition, the DR‐poly(sodium vinyl sulfonate) (PSVS) multilayer films were also fabricated on AAP surface via self‐assembly technique. The DR‐PSVS multilayer film, which can dissolve in sodium dodecyl sulfate (SDS) aqueous solution, becomes insoluble after UV‐irradiation due to the linkage conversion between the layers from ionic bond to covalent bond.
