Abstract: The present invention relates to radiation curable compositions, comprising (A1) at least one water-soluble reactive diluent (A1); (A2) at least one water-soluble reactive oligomer (A2); (B) at least one reactive component selected from the group consisting of a water insoluble reactive diluent (B1a), a slightly water-soluble reactive diluent (B1b) and a water insoluble, or slightly water-soluble reactive oligomer (B2); and (C) optionally a photoinitiator (C), wherein the amount of component (A1) and (A2) is greater than 20% by weight, especially 30% by weight based on the amount of components (A1), (A2), (B1a), (B1b) and (B2) and the amount of components (B1a), (B1b) and (B2) is greater than 10% by weight, especially 20% by weight based on the amount of components (A1), (A2), (B1a), (B1b) and (B2); radiation curable composition, comprising (A1′) at least one slightly water-soluble reactive diluent (B1b); (A2) at least one water-soluble reactive oligomer (A2); (B) at least one reactive component selected from the group consisting of a water insoluble reactive diluent (B1a) and a water insoluble, or slightly water-soluble reactive oligomer (B2); and (C) optionally a photoinitiator (C), wherein the amount of component (B1b) and (A2) is greater than 40% by weight, especially 50% by weight based on the amount of components (A2), (B1a), (B1b) and (B2) and the amount of components (B1a), (B1b) and (B2) is greater than 10% by weight, especially 20% by weight based on the amount of components (A2), (B1a), (B1b) and (B2). The radiation curable compositions can be cleaned by pure water with no assistance of any solvent or detergent. The printed three-dimensional products have clean, smooth, tack-free surface after washing with water and sufficient post-curing. The fully cured three-dimensional products are high-temperature resistant and have excellent mechanical performance above glass transition temperature, e.g. 200° C.
