The phenomenon that letters and symbols by markers on concrete slab seep on the surface of polymer based flooring materials after several years of completion becomes a problem.
In this report, for the purpose of reproducing the stain experimentally and for the marker which is relatively widely used in the field, typical polymer based flooring materials and organic adhesives were combined, and accelerated curing test and thin-layer chromatography test were carried out.
As a result of the test, there was a correlation between Rf value of the marker ink with respect to the degree of seepage of the ink.
