    Abstract: 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.

    Abstract: Photopolymerisable recording material with at least one photopolymerisable, olefinically unsaturated organic cpd. (I), 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 sensitizer (V) and opt. further additives and/or assistant, the (V) comprising at least one cpd. of formula in which A = a residue of formula (VI), (VII) or (VIII) R = H or 1-8C alkyl; R1 = 1-12C alkyl, 1-12C alkoxy, phenyl or NR5R6 in which R5 and R6 (same or different) = 1-6 C alkyl, allyl, phen-C1-4 alkyl, phenyl (opt. substd.), 1-12C alkyl (opt. substd.) or oxaalkyl with 3-12 C and 1-5 0 atoms, or R5 and R6 together form a heterocyclic satd. or unsatd. ring; R2 = H, 1-12C alkyl, 1-12C alkoxy, halogen or trialkylsilyl; n = 1 or 2; R3 and R4 (same or different) = 1-8 C alkyl, cycloalkyl, C02R7 in which R7 = 1-8C alkyl or aryl, or phenyl (opt. substd.) or R3 and R4 together may form a carbocyclic or heterocyclic, satd. or unsatd. condensed ring system which may be opt. substd. with the proviso that the long wave absorption max. of the cpd. (V) is below 420 nm, pref. below 400 nm.

    Abstract: Compositions which can be crosslinked under an atmospheric oxygen atmosphere by means of ultraviolet irradiation and are based on (meth)acrylate copolymers having a K value of from 10 to 100, obtained by free-radical polymerisation in solid phase or solution of a) 5 to 97.4% by weight of i-amyl acrylate and/or i-amyl methacrylate and b) 0 to 89.9% by weight of (meth)acrylates whose hompolymers have a glass transition temperature of below -30 DEG C, c) 2.5 to 30% by weight of alpha , beta -monoolefinically unsaturated compounds whose homopolymers have a glass transition temperature of above - 30 DEG C, d) 0 to 10% by weight of monoolefinically unsaturated acids and/or anhydrides thereof, e) 0 to 20% by weight of further olefinically unsaturated monomers containing at least one of the following functional groups: hydroxyl, amide, epoxide, ether, ester, urethane, urea, primary, secondary or tertiary amine and ether, and f) 0.1 to 5% by weight of a copolymerisable benzophenone or acetophenone derivative, the sum of the percentages by weight x = a + b + c + d + f in each case being 100.
