Photoinitiator free (meth)acrylate copolymer based coating agent, adhesive or sealant, comprises a (meth)acrylate copolymer or a compound that is activated by actinic radiation

摘要

A photoinitiator free (meth)acrylate copolymer based coating agent, adhesive and sealing composition has an actinic activatable group content of 700-400 milliequivalents/100 g solid and comprises at least one (meth)acrylate copolymer that contains a group that is activated by actinic radiation or at least one compound containing at least one actinic radiation activatable bond. A photoinitiator free coating agent, adhesive and sealing composition (I) has an actinic activatable group content of 700-400 milliequivalents/100 g solid and comprises: (A) at least one (meth)acrylate copolymer that on average contains at least one group (A1) that contains a bond that is activated by actinic radiation, in which the group is bonded to the base (meth)acrylate copolymer structure by polymer-analogue reactions; or (B) at least one compound that on average contains at least one group (A1) having at least one actinic radiation activatable bond; and (C) at least one (meth)acrylate copolymer that is free of groups (A1). An independent claim is included for a process for the production of coatings, adhesive layers and/or seals by application of the composition (I) to optionally primed substrates and curing of the resulting layer with actinic radiation.
