Hybrid pigments have attracted great interest due to their stability and physicochemical properties that can be used in paintings, artworks and in the field of cultural heritage. The study of new materials includes the search for new pigments by immobilization of the dyes in resistant substrates such clays minerals to get new colour fonts and materials with high stability. Organic-inorganic based lake pigments, at different pH, have been prepared. Ti- and Al-pillared montmorillonite were synthesized and loaded with carminic acid (CA) and alizarin (Aliz) organic dyes. The pillaring process was investigated by X-ray diffraction, textural analysis, transmission electronic microscopy and solid state nuclear magnetic resonance of ²⁷Al. The interactions between the organic guest and the inorganic host were highlighted by infrared, ¹³C and ²⁷Al solid state magnetic nuclear resonance and time resolved fluorescence spectroscopies. The spectra support complex formation between the chromophores and the inorganic matrix. The colours of the pigments prepared were pH dependent. Lake pigments based on Al-Pillared Mt were more stable under light than Ti-based hybrid, even in oil painting formulations.

杂合颜料由于其稳定性和可用于绘画，艺术品和文化遗产领域的理化特性而引起了极大的兴趣。新材料的研究包括通过将染料固定在耐性基材（例如粘土矿物）中来寻找新颜料，以获得具有高稳定性的新颜色字体和材料。已经制备了在不同pH下的基于有机-无机的色淀颜料。合成了钛和铝柱状蒙脱土，并负载了氨基甲酸（CA）和茜素（Aliz）有机染料。柱化方法，通过X射线衍射，纹理分析，透射电子显微镜和固态核磁共振研究²⁷铝 红外，¹³ C和²⁷ Al固态核磁共振和时间分辨荧光光谱法突出了有机客体与无机主体之间的相互作用。光谱支持生色团和无机基质之间的络合物形成。制备的颜料的颜色取决于pH。即使在油画配方中，基于Al柱状Mt的色淀颜料在光下也比基于Ti的杂化物更稳定。
