PHOTOPOLYMERISIERBARE AUFZEICHNUNGSMATERIALIEN SOWIE PHOTORESIST-SCHICHTEN UND FLACHDRUCKPLATTEN AUF BASIS DIESER AUFZEICHNUNGSMATERIALIEN.

摘要

Photopolymerisable recording material contains at least one photopolymerisable, olefinically unsatd. organic cpd. (1), opt. a polymeric binder (II), at least one photopolymerisation initiator (III), a colour forming system (IV) which on irradiation with actinic radiation causes an increase in the colour intensity of the recording material, a sensitiser (V) and opt. further additives and/or assistants. (V) comprises at least one cpd. of formula (V) or (VI) in which X = CH or N; Y = H, 1-12 C alkyl, 1-12 C alkoxy or halogen; R1 = 1-12 C alkyl, 1-12 C alkoxy, or halogen; R1 = 1-12 C alkyl, 1-12 C alkoxy, CF3, phenyl or NR4R5 (in which R4 and R5 = 1-6 C alkyl, allyl, phen-C1-4alkyl, phenyl, etc.); and R2 and R3 = 1-12 C alkyl, 1-12 C alkoxy, hydroxy-C1-4alkyl, oxaalkyl with 2-12 C and 1-5 O atoms, phen-C1-4alkyl, phenyl, naphthyl, aryl susbtd. b y 1-4 C alkyl, 1-4 C alkoxy, phenyl, CF3, trialkylsilyl, CN, -O-CO-C1-12alkyl, -CO-O-C1-12alkyl, etc.. The long wave absorption max. of cpd. (V) is below 420 nm, pref. below 400 nm.
