Definitions

• the invention relates to a cigarette mouthpiece covering paper, consisting of a base paper of lo - 4o g / m2 weight and a printed printing ink.
• Such cigarette tip papers have been known for decades.
• colored papers were used as the base paper, more recently white papers are used, which are printed twice with printing ink.
• These are papers that are used as a filter wrapper, as a mouthpiece or as a filter or mouthpiece coating.
• the printed printing ink has organic solvents, which are removed from the printed cigarette mouthpiece covering paper by evaporation after drying in drying systems and are passed into the free environment by suction systems.
• the environmental protection authorities have also requested recovery systems for the solvent so that the smell of the solvent does not affect local residents who are close to production facilities.
• Such systems are expensive and expensive to operate because they consume significant amounts of energy.
• the base papers used must have a number of technical properties, such as a special tear strength, for example, in order to be able to fast forward of printing and quick drying following the printing, but also to be able to be processed quickly in the cigarette machines. For this reason, the industry uses a base paper which has a water absorption capacity of about 17 g / m2 in 60 seconds, measured in the Cobb test.
• the invention consists in that a base paper is used as paper which in the Cobb test has a water absorption capacity of 6-12 g / m 2 in 60 seconds, that at least 60% of water is used as solvent in the printing ink and that as a binder for the Pigments shellac is used.
• Such a cigarette tip paper has the advantage that the print gives an improved picture, which may be due to the fact that when using shellac on the surface, pigments are exposed which were completely enclosed by the binder in the previously used binders the printing ink due to moisture or water on the lips of the consumer is not possible because the shellac after it has solidified in the drying process after the printing process can no longer be solved by simple water. This is also the reason why the pigment exposed on its surface facing away from the paper cannot be detached from the paper or the binder between the pigment and the paper.
• drying water as a solvent does not pose any environmental problems. The ink can be extinguished with water in the event of fire, if it catches fire at all. That is also a Advantage during transport and storage because no special precautionary measures against fire have to be taken.
• a cigarette tip paper is produced with a light brown base paper, which has 3o g / m2 weight and a water absorption capacity of 9 g / m2 in 60 seconds in the Cobb test.
• This base paper is printed with a printing ink containing 9o% water and 1o% ethyl alcohol as a solvent.
• Shellac is used as a binding agent used in the following composition: 40% solvent 15% shellac 35% pigments, which are composed of mixtures of iron oxide and titanium oxide.
• This ink was applied to the base paper on a conventional printing machine, as has been used for years in the manufacture of cigarette tip paper. With the same drying times, there were improved images compared to printing inks with organic solvents.
