| titleOfInvention | Improvements in or relating to photopolymerisable compositions |
| abstract | A photopolymerizable composition comprises (a) an addition polymerizable, non-gaseous, ethylenically unsaturated compound containing at least one terminal ethylenic group (CH2=C<) having a boiling point above 100 DEG C. at normal atmospheric pressure and being capable of forming a high polymer by free-radical initiated addition polymerization; (b) at least one sensitometric modifier containing an organic compound of the formula -N=C<, wherein the nitrogen atom is also linked to a single oxygen atom, said modifier being present in an amount from 0.001 to 3.0% by weight of constituent (a); (c) a free-radical generating addition polymerization photoinitiator activatable by actinic radiation, in an amount from 0.001 to 10 parts per 100 parts of the total photopolymerizable composition. The compositions preferably also contain (a) a viscosity modifying agent, preferably a thermoplastic compound which is solid at least at 50 DEG C., such agents include filler materials, both inorganic and polymeric, plasticizers and high boiling solvents, and (e) a thermal addition polymerization inhibitor. Preferably the sensitometric modifier (b) contains a compound of formula <FORM:1001834/C3/1> wherein the nitrogen atom is linked to a single oxygen atom and (1) the monovalent bond of the nitrogen atom may be attached to a hydrocarbon radical (R); when the carbon atom is attached to a hydrogen atom (R1), its remaining bond is attached to an aromatic ring system (R11) and when the carbon atom is not attached to hydrogen, it is part of a carbocyclic ring system (R1 and R11) and (2) the nitrogen atom may not carry a substituent R (R=zero) and R1 and R11 are a benzenoid ring system containing an amino group. Still more particularly the sensitometric modifier (6) may be represented by one of the following formula <FORM:1001834/C3/2> wherein R is hydrogen, alkyl, hydroxyalkyl, phenyl, R1 which may be the same or different to R, is alkyl, hydroxy alkyl, phenyl, acetamido, N1-alkyl, N1,N1-dialkyl substituted acetamido or p-sulphophenoxybutyl <FORM:1001834/C3/3> wherein the carbon atom is part of a carbocyclic ring system or is attached to hydrogen and an aromatic ring system, and the monovalent bond of the nitrogen atom is attached to a hydrogen or substituted hydrocarbon radical. Long lists of suitable monomers are supplied alkylene and polyalkylene glycol diacrylates being preferred. Specifications 741,441, 741,470, 807,948, 905,700, 935,627, 945,807, 1,001,831, 1,001,832 and 1,001,833 are referred to. |
