UV curable compositions, polymeric photoinitiators and precursors therefor are described.

Polymeric photoinitiators

Thermally shrinkable films or labels having coated thereon a radiation curable adhesive; and a process for applying thermally shrinkable films or labels to containers comprising the steps of a) coating at least a portion of a thermally shrinkable but unshrunken film or label segment with a radiation curable adhesive; b) applying the film or label to the longitudinal surface of the container; c) subjecting the radiation curable adhesive to a radiation source to effect curing thereof and, d) subjecting the container to heat to shrink the film or label onto the container so as to permanently affix it thereto.

Adhesives for thermally shrinkable films or labels

Provides high vinyl, radial multi-block styrene-butadiene-styrene-containing hot melt adhesive compositions that are radiation-curable to yield pressure-sensitive adhesive films with improved peel adhesion and cohesive strength, especially at elevated temperatures. These pressure-sensitive adhesive tapes are ideally suited for tape and label applications requiring good cohesive strength at elevated temperatures and yet are readily removed from painted or other surfaces leaving no adhesive residue.
