Abstract

A curable adhesive composition comprises (a) at least one polymer comprising polymerized units derived (or derivable) from at least one (meth)acryloyl-functional monomer or oligomer; (b) at least one (meth)acryloyl-multifunctional monomer or oligomer; (c) at least one multifunctional epoxide; (d) at least one free radical initiator; and (e) at least one cationic initiator; wherein the composition is optically clear and remains optically clear during and after curing.

Description

technical field The present invention relates to curable adhesive compositions. In other aspects, the invention also relates to methods of their use and substrateless tapes and articles comprising the compositions. Background technique Pressure sensitive adhesives (PSAs) exhibit many desirable properties, including ease of application, and have been used in a variety of applications. However, for more permanent bond applications, some conventional PSAs lack sufficient strength to maintain bonds to some substrates, especially when exposed to high temperatures or higher humidity. For example, application of some conventional PSAs to optical substrates such as poly(methyl methacrylate) or polycarbonate, which are known as "outgassing substrates" that are difficult to bond, can result in blistering and delamination. In particular, in optical applications, the aforementioned blistering and peeling are unacceptable. Curable adhesives (eg, heat or light curable adhesives) have ...
