The most suitable organic-coatings used as protection were selected for the special requirements of the colored pottery. In the experiment of the artificial ageing irradiation, the changes of molecular structure, color determination and adhesive strength were respectively investigated by a Tensor 27 FTIR spectrometer with the ATR accessory, spectrophotometer and adhesive-strength testing apparatus (made by ourselves). The results indicated that the changes of stabilization, the color and adhesive strength in Primal AC33, B72 and organic-silicon were less than those of others. In conclusion, Primal AC33, B72 and organic-silicon have excellent performance in the conservation of the colored pottery and can be widely used as protective materials in the relic conservation
