Process for the production of a hydroxyl group containing epsilon -caprolactone modified (METH) acrylate resin

摘要

Acrylate and methacrylate resins containing hydroxyl groups and modified by epsilon -caprolactone are produced by producing an adduct of a hydroxyalkylacrylate or methacrylate and epsilon -caprolactone in a first step and then in a second step radically copolymerizing this product with further acrylic acid or methacrylic acid esters and optionally vinyl aromatics in a suitable varnish solvent. The thus obtained copolymerizate solutions after addition of a polyvalent isocyanate are used to produce coatings on substrates and give a baked on lacquer coating with outstanding adhesion to the base.
