SELF-PHOTOINITIATING MULTIFUNCTIONAL URETHANE OLIGOMERS CONTAINING PENDANT ACRYLATE GROUPS

摘要

The present invention relates to self-photoinitiating multifunctional urethane acrylate compositions. More particularly, the present invention relates to liquid oligomeric multifunctional acrylate compositions having pendant acrylate groups and tertiary amine groups bound as part of the polymer structure. The compositions of the present invention cure upon exposure to active radiation such as UV light in the absence of an added photoinitiator. Films made from the crosslinked oligomers of the invention are used as protective or decorative coatings on various substrates. These oligomers can be added to other resins used in adhesives or composites.
