Description

Ink composition providing fragrance using microencapsulated compound

Field of Invention

The present invention relates to an ink composition, especially a scented ink composition utilizing microcapsule compounds.

Background of the Invention

The additives in general ink are colorants, surfactants, acid-base buffers, etc., most of which are organic compounds, which inevitably have a little pungent smell, and this pungent smell often creates an unpleasant atmosphere for users, so Ink manufacturers add fragrances that can produce fragrance to the ink to improve this problem and open up another business opportunity.

Spices are divided into two types according to the source of fragrance. The first one is natural fragrances: natural fragrant substances are obtained through separation operations such as extraction, concentration, oil extraction, distillation, etc. Natural fragrances are divided into plant-based fragrances and animal-based fragrances. . The second type is synthetic fragrances, which are synthetic fragrances produced by chemical synthesis, which are divided into natural synthetic fragrances and petrochemical fragrances.

Spices are divided into five grades according to the essence content contained in them. (1) Essence: also known as concentrated perfume, the essence content is more than 20%, which is the highest grade of perfume. (2) Perfume: the essence content is 15-20%, and the price is more popular than essence. (3) Fragrant dew: the essence content is 8-15%, which is the grade with the best response in the market. (4) Cologne: The essence content is 4 to 8%, and most male perfumes belong to this level. (5) Eau de Toilette: The essence content is 1-3%.

The types of perfumes can be classified into flower perfumes and fancy perfumes. Floral fragrances are based on natural floral fragrances, such as rose, jasmine, moonflower and other single floral fragrances. Emotional perfume, also known as fantasy perfume, is a fragrance that expresses the imagination of the perfumer with natural objects other than flowers, such as forests, vegetation, place names, scenery, people, music, and atmosphere.

Generally speaking, spices are mostly oil-soluble and insoluble in water. The ink is mainly an aqueous solution, so if you want to apply fragrances to the ink, you must use other solvents, such as ethanol. In US Patent No. 6,123,757, a special perfume ink composition is disclosed, which includes an alcohol compound, an image-forming compound, fragrance compound, deionized water and ethanol. The patent is to add fragrance-containing aromatic compounds into the ink, so that the printed text or pattern emits fragrance, so as to cover up the bad smell. The aromatic compound of this patent is an organic compound, which is dissolved in ethanol, and the aromatic organic compound is dispersed in the ink by virtue of the solubility of ethanol. However, due to the poor emulsification ability of ethanol, the aromatic organic compound cannot be completely dissolved in the ink. This phenomenon not only cannot effectively provide the source of aroma, but also may cause blockage of the nozzle due to uneven dispersion. Moreover, due to the low boiling point and high volatility of ethanol, it is easy to accelerate the emission of fragrance, resulting in that the fragrance of the printed text or pattern cannot last. Furthermore, the addition of ethanol to the ink will reduce the surface tension of the ink, and instead increase the penetrating power of the ink to the paper, resulting in negative effects such as dullness and blurring of characters or patterns on the paper.

As can be seen from the above, it is still to be developed to provide a scented ink without affecting the original condition of the ink.

                         

In view of this, the main purpose of the present invention is to provide a scented ink composition.

The present invention provides an ink composition that utilizes a microcapsule compound to emit fragrance. The ink composition includes: a microcapsule compound to provide the ink composition with an aromatic smell; a colorant to provide the color of the ink composition; Agents and emulsifiers; and media including surfactants, acid-base buffers, chelating agents, bactericides, preservatives, humectants, organic solvents, and anti-ultraviolet agents.

The particle size of the microcapsule compound of the present invention is less than 1 μm, and its added weight percentage range is about 0.01%-10%. The microcapsule compound of the present invention has natural spices, synthetic spices or mixtures thereof, wherein natural spices include: rose oil, ginger oil, citronella oil, white sandalwood oil, rosemary, lavender oil, fennel oil, jasmine oil, cinnamon oil , clove oil, ylang oil, turpentine, musk, civet, castoreum, ambergris; and synthetic fragrances include: β-caryophyllene, linalool, α-Terpinol (α-terpineol), cinnamaldehyde (cinnamaldehyde), salicylic aldehyde (salicylic aldehyde), allyl caproate (allyl caproate), β-ionone (β-lonone), maltol (maltol), synthetic musk ( musk ambrette), anethole, thymol, eugenol, isosafrol, benzoic acid, methyl phenylacetate, oxide ketone), bromostyrene (1-bromo-2-phenylethylene).
