Positive-working radiation-sensitive mixture

摘要

The invention relates to a positive-working radiation-sensitive mixture containing a) a polymeric binder having acid-labile groups and b) a compound which forms a strong acid on irradiation, in which the binder simultaneously contains units of the formulae I, II and IIIR1-OH(I),R1-O-CO2R2(II)R1-O-CH2-CHR3-OH(III).The mixture is used to coat radiation-sensitive recording material which can be used to produce printing plates and photoresists.
