| 发明名称 | UV- and thermally curing clearcoat composition for automotive refinishing | ||
| 摘要 | An UV- and thermally curable, solventborne clearcoat material suitable for automotive refinishing comprises: (A) at least one polyhydroxy-functional poly(meth)acrylate having grafted-on unsaturated (meth)acrylate side groups,(B) at least one polyisocyanate-functional, poly(meth)acrylate-functional aliphatic urethane,(C) at least one (meth)acrylate-functional aliphatic urethane free from isocyanate groups,(D) at least one hydroxy-functional, (meth)acrylate-functional aliphatic component free from isocyanate groups and from urethane groups and having a molecular weight of not more than 1000 g/mol and a (meth)acrylate functionality of at least 4,(E) at least one aliphatic polymercaptan,(F) at least one phosphoric acid or phosphonic acid blocked with an amine, the amine possessing a pKb of ≧3 and a boiling point under atmospheric pressure of >100° C., and(G) at least one photoinitiator selected from the group consisting of α-hydroxyalkyl phenyl ketones and monoacylphosphine oxides.;Component (A) may be an intermediate in the production of the clearcoat material. | ||

| 主权项 | 1. An UV- and thermally curable, solventborne clearcoat material comprising (A) at least one polyhydroxy-functional poly(meth)acrylate having grafted-on unsaturated (meth)acrylate side groups, (B) at least one polyisocyanate-functional aliphatic urethane containing at least two (meth)acrylate groups, (C) at least one (meth)acrylate-functional aliphatic urethane free from isocyanate groups, (D) at least one hydroxy-functional, (meth)acrylate-functional aliphatic component free from isocyanate groups and from urethane groups and having a molecular weight of not more than 1000 g/mol and a (meth)acrylate functionality of at least 4, (E) at least one aliphatic polymercaptan, (F) at least one phosphoric acid or phosphonic acid blocked with an amine, the amine possessing a pKb of ≧3 and a boiling point under atmospheric pressure of >100° C., and (G) at least one photoinitiator selected from the group consisting of α hydroxyalkyl phenyl ketones and monoacylphosphine oxides. | ||
