Abstract
A pressure-sensitive laminate composition is described which enables the easy detection of improperly die-cut patterns which has a backing material, a silicone release coating, a non-migratory colorant dispersed in the silicone, a pressure-sensitive adhesive, and a face stock. Alternatively, a release liner composition is described having a non-migratory silicone coating on a backing material. One colorant used is carbon black. The carbon black is dispersed in the release layer either in a solvent-free system, or in an organic medium, which is preferably a mixed organic solvent, in which at least one of the solvents used is at least partially polar.
