Boron type compound solution

SUBJECT of the Invention A high concentration boron type compound is contained and the boron type compound solution which can be preserve|saved long term-stable is provided. PROBLEM to be solved The boron type compound solution disclosed is comprised so that preparation of the 1st solution and the 2nd solution is possible. The 1st solution contains 3 to 15 weight% of boron type compounds， and 85 to 97 weight% of 1st solvent. The 2nd solution contains 20 to 50 weight% of boron type compounds， and 50 to 80 weight% of 2nd solvent. A 1st solvent is water and a 2nd solvent is at least 1 sort(s) selected from the group which consists of glycol， a polyhydric alcohol， or a salt. SELECTED DRAWINGS Absence
