This invention pertains to a curable composition comprises at least one monomer having at least one (meth)acrylate end group, selected from the group consisting of (meth)acrylate esters of alcohols having at least seven consecutive carbon atoms, and alkoxylated derivatives thereof; optionally, a (meth)acrylate oligomer in an amount of at least 1 wt% and at most 40 wt% based on the weight of the composition other than E) the filler; at least one non-reactive diluent in an amount of at least about 5 wt% and at most 40 wt% based on the weight of the composition other than E) the filler; a free radical photoinitiator; and at least one filler in an amount of at least 30 vol% based on the total volume of the curable composition. This composition is suitable for use in the fabrication of articles, such as ceramic articles, including industrial, consumer and medical products and molds used for casting and thermoforming articles. This invention is also directed to a method for making an article comprises curing the composition then sintering it.

The present invention relates to a curable composition comprising: a) at least one alkoxylated isosorbide di(meth)acrylate, b) at least one (meth)acrylate-functionalized oligomer, and c) at least one (meth)acrylate-functionalized monomer. The invention also relates to a process for the preparation of a cured product, especially a dental material, comprising curing this curable composition, preferably by exposing the curable composition to radiation such as UV, near-UV, visible, infrared, near-infrared and/or electron beam radiation.

A curable composition in the form of a slurry comprises an electrode particulate material; a (meth)acrylate oligomer; a solvent; an adhesion promoter comprising a (meth)acrylated phosphate ester; and optionally a (meth)acrylate monomer and/or a free radical photoinitiator. This composition is suitable for use in the fabrication of electrodes of lithium ion batteries. In particular, the composition may be applied to a current collector, then cured to form a cathode or an anode. It has been found that this composition provides electrodes having an homogeneous surface which is deprived of cracks and also enhanced adhesion of the electrode particulate material to current collectors used in lithium-ion batteries.

The present invention relates to curable compositions comprising additives useful for preventing the formation and entrapment of bubbles during 3D printing and to methods for preventing or restricting bubble formation and entrapment in 3D printed compositions. More specifically, this invention pertains to a curable composition comprising: (A) a free-radically polymerizable resin comprising at least one (meth)acrylate-functionalized compound; (B) a free radical photoinitiator; (C) optionally, at least one cationically polymerizable compound and a cationic photoinitiator; and (D) at least one specific wetting agent present in an amount of 1 to 15 weight percent based on the weight of the curable composition. The additives described herein are useful across a wide range of 3D printed articles because the presence of bubbles in the curable composition may impact either or both of the operability or the aesthetics of a 3D printed article.
