Abstract
Fluorescent probes (FP) were suggested to analyze spatial distribution of hydrophobic natural and synthetic restoration materials (HRM) in monuments with a prevailing mineral phase. Experimental proof is given that FP that were found luminesce selectively only within HRM and do not luminesce in chemical bonding and nonspecific sorption with a mineral phase. FP make it possible to visualize many types of HRM distribution (films, filling of large cavities and cracks, uniform impregnation) in the two-phase systems of HRM + mineral. Characteristics are given of spatial distribution of solutions and dispersions of some synthetic polymers in model chalk samples, obtained by means of FP.
