    摘要： A redox curing dental composition comprising:
    (a) one or more compounds having a radical polymerizable carbon-carbon double bond;
    (b) a redox initiator system comprising
    (i) a reducing agent which is a compound of the following formula (I):

    wherein
    R 1 and R 2
    which may be the same or different, independently represent a C 1-18 hydrocarbyl group, or R 1 and R 2 form together with the silicon atom to which they are bonded a 3 to 8-membered silicon-containing alicyclic ring, which groups R 1 and/or R 2 may be substituted with one to three substituents selected from the group consisting of a C 1-6 alkoxy group, a halogen atom, or a carboxylic acid group; and
    (ii) an oxidizing agent adapted to oxidize the reducing agent of formula (I) in the absence of light for generating a radical capable of initiating radical polymerization of the one or more compounds having a radical polymerizable carbon-carbon double bond.

    摘要： An additive manufacturing process comprising:
    (a) providing a curable composition comprising:
    (i) a filler comprising glassflakes having a diameter D 3,99 as determined by light scattering in the range of from 5 to 150 µm; and
    (ii) one or more curable compounds;
    (b) controlling an apparatus to form an object by using the curable composition, whereby the curable composition passes a discharge orifice having a minimum diameter Φ min ,
    wherein the ratio of the minimum diameter of the discharge orifice to the diameter D 3,99 of the glassflakes (Φ min /D 3,99 ) is in the range of 2 to less than 10.
