    Abstract: In a photo-polymerisable mixt. contg. at least one ethylenically unsatd., photo-polymerisable or photo-crosslinkable cpd. as well as a photopolymerisation initiator, the photo-polymerisation-initiator comprises a combination of (a) at least one benzophenone, anthraquinone, xanthone or thioxanthone type cpd. having formula (I); where A = H, opt. substd. alkyl, -NR1R2 or -OR3; R1, R2 each = H or opt. substd. aliphatic, aromatic or aliphatic-aromatic gp.; R3 = H or opt. substd. aliphatic, aromatic or aliphatic-aromatic gp.; B = a gp. having the significance of A, halogen or -CN; X = -O-, -S- or -NR4-; R4 = H or an aliphatic, aromatic or aliphatic-aromatic gp.; Y = a direct bond, -CH2-, -CH2-CH2-, -O-, -S-, -CO- or -NR5; R5 = H, an aliphatic or aromatic gp. and n = 0 or 1, and (b) at least one halogen-substd. Me gp.-contg. sym. triazine cpd. having formula (II); where R6, R7, R8 each = opt. substd. alkyl, opt. substd. aryl or opt. substd. aralkyl, provided that at least one of the gps. R6 and R8 is a mono-, di- or tri-halogen-substd. Me gp. and one of the R6, R7, R8 gps. can also be opt. substd. alkenyl, -NR2-, -OR-or -SR-; R = H, alkyl or aryl. A photo-sensitive recording material contains a dimensionally stable carrier and an applied photo-sensitive recording layer having thickness 0.1-50 micron, consisting of the photo-polymerisable mixt. claimed.

    Abstract: A photosensitive recording element which is suitable for the production of printing plates or resist images, possesses a photopolymerizable recording layer which is applied to a dimensionally stable base, can be developed in an aqueous alkaline medium and contains, as a polymeric binder, one or more film-forming copolymers which are insoluble in water but soluble or dispersible in aqueous alkaline solutions and consist of from 10 to 50% by weight of one or more hydroxyalkyl (meth)acrylates, from 8 to 30% by weight of acrylic acid and/or methacrylic acid and from 30 to 80% by weight of one or more alkyl (meth)acrylates, some of the carboxyl groups of the copolymer being esterified by reaction with glycidyl (meth)acrylate.
