Beschreibung
Zusammenfassung:	This invention relates to aqueous, radiation-hardenable emulsions produced from mixtures of the following: (A) from 90 to 50%, by weight, of at least one acrylate prepolymer, containing, per 100 g, from 0.2 to 0.65 mols of (meth)acryloyloxy groups and having a viscosity of from 500 to 300,000 mPa.s, measured at 20 DEG C.; (B) from 10 to 50%, by weight, of at least one emulsifier polyester having a viscosity of from 2,000 to 200,000 mPa.s, containing, per 100 g: (1) from 0.06 to 0.28 mols of condensed units of an alpha - beta -mono-olefinically unsaturated dicarboxylic acid; (2) from 0.04 to 0.34 mols of benzyloxy groups; and (3) from 30 to 80%, by weight, based on emulsifier polyester, of alkylene-oxy groups (-alkylene-O-); the sum of (A) and (B) amounting to 100%, (C) from 25 to 400%, by weight, of water; and (D) from 0 to 10%, by weight, of at least one conventional photoinitiator; the percentage contents of (C) and (D) being based on the sum of (A) and (B). The emulsions are used in particular for coating wood and wood-like materials.
