Definitions

  • This invention relates to the field of inks and paints containing microencapsulated chemicals and particularly to a water color paint containing microencapsulated chemicals which may be printed to form layers and subsequently re-wetted and transferred to paint art having "scratch and sniff" properties.
  • microencapsulated chemicals to create scent and flavor effects is well known.
  • the common "scratch and sniff” technique has been utilized to combine fragrance effects with printed material.
  • microencapsulated fragrances have been used to create “scratch and sniff” books or advertisements. A viewer of the material would scratch the printed areas resulting in a rupture of microcapsules such that the fragrance would be released and smelled.
  • microencapsulated fragrances and printing materials relates almost exclusively to printing of a material such that the next step in the use of the material is the rupture of the microcapsules and release of the chemical. None of these prior art formulations provide a paint or ink containing microcapsules which may be initially printed but then subsequently transferred as the user desires.

  • the liquid mixture of microcapsules and water color paint are printed on a substrate, such as paper, to form layers of water color paint containing microcapsules on the substrate. These layers of water color paint and microcapsules are then allowed to dry to form dry cakes or films of the water color paint and microcapsule mixture.

Abstract

Une peinture à l'eau de couleur imprimable (18) contient des parfums microencapsulés (16) et est destinée à être imprimée sur un substrat (12) afin de former des couches séchées de peinture et de microcapsules (14) à des fins de transfert ultérieur par un utilisateur. Une peinture à l'eau de couleur (18) est mélangée à des microcapsules contenant un parfum désiré (16) pour obtenir un mélange (14) d'une peinture à l'eau en couleur contenant des pigments dissous dans lesquels sont dispersés des parfums microencapsulés. Le mélange liquide est ensuite imprimé pour former des couches de mélanges (14) de peinture et de microcapsules sur un substrat (12). On laisse ensuite les couches (14) sécher afin de former des couches séchées de pigments et de parfums microencapsulés. Ensuite, la peinture (18) et les microcapsules (16) peuvent être transférées en mettant en contact la couche séchée avec une brosse qui a été mouillée de solvants de sorte que le pigment (18) se redissout et les microcapsules (16) se redispersent dans le solvant. Le contact de la broche avec la couche sert également à charger la brosse de pigments dissous (18) et de microcapsules dispersées (16) de sorte que le mélange (14) peut ensuite être transféré vers une autre surface ou un autre objet et peut sécher. Après séchage du mélange transféré, les microcapsules (16) peuvent être cassées en appliquant une force de cisaillement sur la surface peinte de manière à libérer les parfums microencapsulés destinés à donner un effet aromatisé ou parfumé.
