Light-sensitive mixture for producing positive or negative relief copies
摘要:
A light-sensitive mixture is disclosed which containsa) a compound having at least one acid-cleavable C-O-C bond,b) a compound which forms a strong acid on exposure andc) a binder which is insoluble in water but soluble in aqueous alkaline solutions andd) a compound having at least one polymerizable or light-crosslinkable olefinic double bond. The mixture is suitable for producing printing plates, relief copies and photoresists, becoming soluble in alkaline developers on short exposure and insoluble on prolonged exposure as a result of crosslinking.
