Pure and doped with xanthene dyes Rhodamine 6G and Rhodamine B polyurethane materials were exposed to intense radiation and tested by means of IR spectroscopy. The sensitizing effect of the dyes on photodestructive processes in the polymers was shown, and it was more pronounced in the case of Rhodam...
