Abstract
A method of disposing an adhesive composition onto a first surface of a first substrate comprises: a) disposing a photoactivatable adhesive precursor composition onto at least a portion of the first surface of the first substrate according to a predetermined pattern, and b) exposing the photoactivatable adhesive precursor composition to actinic electromagnetic radiation, thereby providing an adhesive precursor composition that spontaneously cures to provide the adhesive composition. The photoactivatable adhesive precursor composition comprises: at least one free-radically polymerizable compound and a photoactivatable redox initiation system comprising: (i) at least one photoactivatable reducing agent precursor; (ii) at least one transition metal compound comprising at least one metal selected from groups 5 to 11 in the Periodic Table of the Elements; (iii) optional organic peroxide; and (iv) optional quaternary ammonium halide. An article preparable according to the method is also disclosed.
