A radiation curable composition is provided herein which comprises suitably about 50-90 parts, preferably about 60-80 parts, by weight, of a multifunctional acrylate monomer, suitably with 3-6 acrylate groups, preferably pentaerythritol triacrylate or trimethylolpropane triacrylate, about 10-50 parts by weight, preferably about 20-40 parts, by weight, of a divinyl ether monomer having both a hydrophobic backbone and an abrasion-resistant moiety, which is preferably the divinylether of cyclohexane dimethanol, and a radiation curing initiator, suitably a cationic initiator, and preferably, in combination with a free radical initiator.

Abrasion and water-resistant radiation curable coatings

This invention is directed to an environmentally safe, water soluble stripping composition which contains a solution of water, a water soluble ester containing from 4 to 10 carbon atoms and an amount of hydrogen peroxide or compounds which generate hydrogen peroxide in situ; which peroxide concentration is not in excess of 30 wt. % of the water/ester composition. The invention also concerns the use of this biodegradable composition in a process for stripping organic coatings such as paints and resins from substrates.
