Definitions
- This invention concerns the ink to be filled into writing tools, e.g. pens, felt pens, roller pens, liner pens, markers, highlight pens etc.
- the inks currently in use are characterized by application properties on which their development focuses. This means they can be removed from textiles by washing, they can be washed off from skin, they cannot be wiped off from nonporous materials, they are resistant against wear etc. These main application characteristics of the inks have some negative properties which the solution under this invention seeks to eliminate.
- the property to be eliminated is the tendency to dry out, which is demonstrated particularly in alcohol-based inks consisting of a mixture of low aliphatic alcohols, pigments and other components, but also in water-based inks containing organic dyes and other components (examples of water-based inks are described in the patent No. 289465 "Washable inks easily removable from skin”).
- the disadvantage of the known writing liquids consists in the fact that the writing tools need to have their writing tips protected against drying. If the tip is not covered with a protective cap for a while it relatively quickly dries out, its function deteriorates and after a longer period of time it is completely degraded.
- the subject matter of the invention consists in the composition of the ink containing 0.1 to 25 wt. % of organic dye or pigment, 0.1 to 40 wt. % of glycols or polyethylene glycols with molecule weights from 100 to 6 000, 0.1 to 20 wt. % of glycol ethers with boiling points over 150° C and up to 15 wt. % of additives and admixtures such as biocides, defoamers, leveling agents, film formers or separators, while the balance to 100 wt. % is water or low aliphatic alcohols or their mixtures.
- the inks under this invention do not dry out even if the tool is not used for writing and left for a long time without a protective cap, which significantly improves capabilities of the products.
- the increased resistance against drying is created particularly by a combination of polyethylene glycols and glycol ethers with high boiling points, which form a layer on the ink surface and prevent evaporation of low-boiling solvents and gradual drying of the ink in the writing tool tip.
- the ink under this invention lasts up to 60 days in an open tip without drying out.

Abstract
The ink with increased resistance against drying under the invention consists of 0.1 to 25 wt.% of organic dye or pigment, 0.1 to 40 wt.% of glycols or polyethylene glycols with molecule weights from 100 to 6000, 0.1 to 20 wt.% of glycol ethers with boiling points over 150° C and up to 15 wt.% of additives and admixtures such as biocides, defoamers, leveling agents, film formers or separators, while the balance to 100 wt.% is water or low aliphatic alcohols or their mixtures. The ink under this invention lasts up to 60 days in an open tip of a writing tool without drying out.
Description
Ink with Increased Resistance against Drying
Background and summary of the invention
This invention concerns the ink to be filled into writing tools, e.g. pens, felt pens, roller pens, liner pens, markers, highlight pens etc. The inks currently in use are characterized by application properties on which their development focuses. This means they can be removed from textiles by washing, they can be washed off from skin, they cannot be wiped off from nonporous materials, they are resistant against wear etc. These main application characteristics of the inks have some negative properties which the solution under this invention seeks to eliminate. The property to be eliminated is the tendency to dry out, which is demonstrated particularly in alcohol-based inks consisting of a mixture of low aliphatic alcohols, pigments and other components, but also in water-based inks containing organic dyes and other components (examples of water-based inks are described in the patent No. 289465 "Washable inks easily removable from skin").
The disadvantage of the known writing liquids consists in the fact that the writing tools need to have their writing tips protected against drying. If the tip is not covered with a protective cap for a while it relatively quickly dries out, its function deteriorates and after a longer period of time it is completely degraded.
The mentioned disadvantage is eliminated by the ink under this invention with the increased resistance against drying.
The subject matter of the invention consists in the composition of the ink containing 0.1 to 25 wt. % of organic dye or pigment, 0.1 to 40 wt. % of glycols or polyethylene glycols with molecule weights from 100 to 6 000, 0.1 to 20 wt. % of glycol ethers with boiling points over 150° C and up to 15 wt. % of additives and admixtures such as biocides, defoamers, leveling agents, film formers or separators, while the balance to 100 wt. % is water or low aliphatic alcohols or their mixtures.
When filled into writing tools, the inks under this invention do not dry out even if the tool is not used for writing and left for a long time without a protective cap, which significantly improves capabilities of the products. The increased resistance against drying is created particularly by a combination of polyethylene glycols and glycol ethers with high boiling points, which form a layer on the ink surface and prevent evaporation of low-boiling solvents and gradual drying of the ink in the writing tool tip. The ink under this invention lasts up to 60 days in an open tip without drying out.
