FIELD: physics.
SUBSTANCE: composition contains 30-80 wt % epoxy-containing compound; 5-40 wt % difunctional (meth)acrylate; cationic photoinitiator; free-radical photoinitiator; optionally one or more stabilisers; 5-40 wt % polyol-containing mixture of at least one component selected from poly(oxytetramethylene)glycol, poly(oxypropylene)glycol, poly(oxyethylene)glycol, polybutadiene with terminal hydroxyl group or polysiloxane with terminal hydroxyl groups, and at least one polyol different from the above-mentioned with higher molecular weight than the above-mentioned; where the percentage by weight is based on the total weight of the photocurable composition.
EFFECT: composition provides a transparent, low-viscosity photocurable composition which can be cured via rapid prototyping with formation of dull white three-dimensional articles having properties similar to acrylonitrile butadiene styrene.
