Sustained-release, print-compatible coatings for fragrance samplers

Abstract

A sustained-release, perfume-containing coating is provided for applications to advertising samplers and the like. A coating is made up of perfume oil having dissolved therein a suitable polymer, and particularly ethyl cellulose, in an amount sufficient to provide a specified viscosity that enables ready application to a substrate by printing and prevents interaction of fragrance oil with a printed image. Advertising samplers having such a coating applied to a paper substrate are also disclosed. The samplers may have a printed image applied thereto underneath the perfume-containing coating. The polymer in the perfume oil serves to modify the oil so as to cause the fragrances therein to be released slowly and without premature release of top-note components. This measure also prevents degradation of the perfume oil from inks used to print images on the sampler.
