Decalcamania with solvent-activated adhesive layers

摘要

A decalcamania or pressure-sensitive dry transfer is described in which at least one design indicium is supported on a temporary carrier sheet from which it is releasable by manipulation of the carrier sheet. The indicium carries a pressure-sensitive adhesive coating, the tack level of which is substantially reduced by the application of a tack-reducing substance so that the multiple sheets of the transfer material can be stacked without blocking. The adhesive can be re-activated prior to use by treatment with a solvent for the tack-reducing substance, such solvent being a non-solvent or poor solvent for the adhesive.
