摘要： An oligomer bearing at least one crosslinkable ethylenic unsaturation and at least one ionic bond comprises in its structure at least one aminoacrylate group and at least one tertiary amine in a form salified with at least one carboxylic acid. Also described are a process for preparing a solution of the oligomer in a reactive diluent, a crosslinkable composition comprising the oligomer, the use thereof as binder in crosslinkable compositions for temporary-use water-removable materials in coatings, hydrogels and 3D object printing, and the crosslinked material which results from polymerizing the oligomer. As a temporary-use material, the cured oligomer can be easily removed after a temporary function, by simple cleaning with water and optionally at a suitable temperature greater than the glass transition temperature of the crosslinked product.

摘要： The invention relates to a crosslinkable composition, which comprises a component a) at least one halogenated bisphenol A diglycidyl ether tetra(meth)acrylate and a component b) at least one diluent from mono(meth)acrylates of a monoalcohol comprising a biphenyl structure, and at least one optional component from components c), d), e), f) and g). It also relates to its use for coatings or materials, in particular for 3D printed articles for optical applications, as it also relates to the crosslinked composition and to the finished product, in particular the 3D article which results therefrom.
