It is shown that the protective layers containing filter dyes (yellow E102, diamond blue С and black E131) allow to reduce influence of background flares; it will increase reliability, reliability and quality of radio graphic control, especially in the conditions of field laboratories when it is difficult to observe a lighting mode.
