    摘要: The invention relates to a liquid resin composition which can be poly­merized by radiation and which contains

    (i) a difunctional monomeric or polymeric acrylate or methacrylate,
    (ii) a tri- or polyfunctional acrylate or methacrylate,
    (iii) at least one unsaturated monofunctional monomeric compound of the formula VI
    wherein R⁵ denotes hydrogen or methyl and R⁶ is a group of the formula VII

    - -O-R⁷      (VII),
    R⁷ being tetrahydrofurfuryl, cyclohexyl, 2-phenoxyethyl, benzyl, isobornyl, glycidyl, dicyclopentenyl, morpholinoethyl, dimethyl­aminoethyl, diethylaminoethyl or a C₁-C₂₀ linear or branched aliphatic residue, or - if R⁵ is hydrogen R⁶ denotes additionally pyrrolidinon-2-yl, imidazonyl, carbazolyl, anthracenyl, phenyl, C₅-C₈cycloalkyl, naphthenyl, 2-norbornyl, pyridyl, N-caprolactamyl or toluyl and
    (iv) a photo-polymerization initiator for (i), (ii) and/or (iii).

    Such compositions are suitable in the stereolithographic process, as coatings or as adhesives.
