Abstract
The present disclosure provides a crosslinkable composition including a (meth)acrylate polymer and a visible light absorbing compound. Two percent or less of the carbon-carbon bonds in the crosslinkable composition are double bonds. The composition allows for inclusion of one or more materials degradable by ultraviolet radiation and/or stabilized against ultraviolet radiation. Methods for making a crosslinked composition is also provided. One method includes obtaining a crosslinkable composition and subjecting the crosslinkable composition to radiation having a wavelength of 400 nm or greater. Another method includes subjecting a crosslinkable composition to first and second radiations that are different from each other.
