Abstract
A scratch-and-sniff coating is provided comprised of a first coating on a substrate having a water- and heat-resistant second coating thereon, the first coating being comprised of a non-encapsulated flavor/fragrance component and a polysaccharide component, and the second coating comprised of a shellac component. The scratch-and-sniff coating is made by forming a first coating comprised of a non-encapsulated flavor/fragrance component and a polysaccharide component and drying the first coating, and forming a water- and heat-resistant shellac-containing second coating on the first coating, and drying the second coating. An encapsulated flavor/fragrance component may optionally be present in the first coating. The scratch-and-sniff coating can be applied to a package for a consumer article.
Claims24
A method of making a scratch-and-sniff coating, comprising the steps of:
- (a) applying on a substrate a coating comprised of a non-encapsulated flavor/fragrance component and a polysaccharide component;
- (b) drying said coating of step (a);
- (c) applying a protective water- and heat-resistant second coating on said dried coating of step (b), said second coating comprised of a shellac component;
- and
- (d) drying said second coating.
A scratch-and-sniff coating comprised of a first flavor/fragrance-containing coating on a substrate, said first coating having a second water- and heat-resistant protective coating thereon, said first coating comprised of a non-encapsulated flavor/fragrance component and a polysaccharide component, and said second coating comprised of a water- and heat-resistant shellac component.
A composition suitable for use in a scratch-and-sniff coating, said composition comprised of at least one non-encapsulated first flavor/fragrance component admixed with a polysaccharide component and at least one additional flavor/fragrance component present in microcapsules present in said composition.
