Fragrance and color varnish with open-pore microcapsules for subsequent loading and continuous release of fragrances and dyes

Abstract

Lacquer comprising microcapsules, ◯ which contain an open-pore carrier material, ◯ the microcapsules can absorb both fragrances and dyes, ◯ and wherein the microcapsules can be charged after application of the lacquer to a surface by external spraying or application of a fragrance and / or dye solution and can be recharged more than once

Description

Technical Field:The invention relates to the coatings industry, in particular cosmetic and decorative coatings. It describes a perfume and color lacquer which contains open-pored microcapsules. These microcapsules can absorb both fragrances and colorants and release them continuously. They can be loaded before or after application of the paint and thus make it possible to adapt individually to fragrance and color profiles.Prior Art:From the prior art, lacquers are known which contain either fragrances or colorants. Conventional solutions, however, offer limited possibilities for adaptation after application. Fragrances often evaporate quickly, while colorants can only be incorporated statically into the formulation. A combined release of fragrances and dyes over longer periods of time and the possibility of subsequent loading of the capsules is not present in the prior art.Object of the invention:The object of the invention is to provide a lacquer which: contains open-pored microcapsules which can absorb and release both fragrances and dyes,◯ microcapsules which can be loaded before or after application of the coating material,This permits a continuous and uniform release of the fragrances and colorants,o permits a flexible adaptation of the odour and colour profile,◯ and consist of lasting, environmentally friendly materials.Solution:The object is achieved by a paint which contains open-pored microcapsules. These microcapsules can absorb fragrances and colorants and can be loaded either before or after application of the coating. The specific capillary structure of the microcapsules ensures uniform release of the fragrances and colorants over a prolonged period of time.Advantages of the Invention:◯ flexibility: microcapsules can be integrated into the lacquer both pre-charged and un-charged.◯ Subsequent Adaptation: Fragrances and colorants can be applied individually after application.◯ Sustained release: Continuous release of fragrances and colorants over days to weeks. sustainability: Rechargeable microcapsules reduce waste and promote environmentally friendly application.◯ Compatibility: Suitable for a wide range of fragrances and colorants, including natural and synthetic substances. Simple processing: The lacquer can be applied to wood, metal, glass, plastic and other surfaces.

Claims
