そして一般に溶剤には、塗布後の乾燥を良くするために
揮発性の高いものが使用されている。In general, highly volatile solvents are used to improve drying after coating.

しかしながら、この種の揮発性の高い溶剤は、人体に害
を与えるものが多く、また可燃性である等取扱いが難し
いという難点があった。(Problems to be Solved by the Invention) However, many of these highly volatile solvents are harmful to the human body and are flammable, making them difficult to handle.
