    Photosensitive mixture
    CA 2028541 A1
    Abstract
    Liquid mixtures containing a) 5-25 % by weight of a monomeric aliphatic or cycloaliphatic di(meth)acrylate having a molecular weight (MW) of not more than 800, b) 0-15 % by weight of a monomeric poly(meth)acrylate having a functionality of at least 3 and an MW of not more than 600, c) 0-20 % by weight of a mono(meth)acrylate or a mono-N-vinyl compound having an MW of not more than 500, d) 20-60 % by weight of a urethane (meth)acrylate having a functionality of 2 to 4 and an MW of 500 to 10,000, e) 10-50 % by weight of a monomeric or oligomeric di(meth)acrylate based on bisphenol A or bisphenol F, f) 0.1-10 % by weight of a photoinitiator and g) 0-5 % by weight of customary additives, the proportion of the components a) to g) together being 100 % by weight, are photosensitive mixtures which can be polymerized by means of actinic radiation and are preferentially suitable for the production of three-dimensional articles by means of the stereolithographic process.
