METHOD FOR MARKING A TREE TRUNCK WITH BIODEGRADABLE AQUEOUS MARKING PAINT SOLUTION AND BIODEGRADABLE AQUEOUS MARKING PAINT SOLUTION

摘要

The invention relates to a method for marking a tree trunk with a biodegradable aqueous marking paint solution, which also contains a rust inhibitor. In the method, upon a tree trunk is sprayed an aqueous marking paint solution, which contains 35-55 wt% water and 40-60 wt% glycerol whose biodegradability as per test method OECD 301 is not more than 30 days, 0,05-1 wt% a colorant, 0,1-2 wt% a corrosion inhibitor, the total amount of glycerol and water in said aqueous solution being nevertheless higher than 95%, preferably higher than 97 wt%.
