Description

溶媒として、例えば、n−ヘキサン、n−ヘプタなどの脂肪族炭化水素化合物;ベンゼン、トルエン、キシレンなどの芳香族化合物;イソプロピルアルコール、n−ブチルアルコールなどのアルコール;プロピレングリコールメチルエーテル、ジプロピレングリコールメチルエーテル、エチルセロソルブ、ブチルセロソルブなどのエーテル;酢酸エチル、酢酸ブチル、セロソルブアセテートなどのエステル;アセトン、メチルエチルケトン、メチルイソブチルケトン、ジアセトンアルコールなどのケトン;ジメチルホルムアミドなどのアミドなどの有機溶媒が挙げられるが、本発明は、かかる例示のみに限定されるものではない。これらの溶媒は、それぞれ単独で用いてもよく、2種以上を併用してもよい。溶媒のなかでは、人体に対する影響を小さくする観点から、脂肪族炭化水素化合物、アルコール、エーテル、エステル、ケトンおよびアミドが好ましく、脂肪族炭化水素化合物およびエステルがより好ましく、n−ヘキサンおよび酢酸エチルがさらに好ましい。 As a solvent, for example, n- hexane, n- aliphatic hydrocarbon compounds such as hepta down; benzene, toluene, aromatic compounds such as xylene; isopropyl alcohol, alcohols such as n- butyl alcohol; propylene glycol methyl ether, dipropylene Examples include ethers such as glycol methyl ether, ethyl cellosolve, and butyl cellosolve; esters such as ethyl acetate, butyl acetate, and cellosolve acetate; ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone, and diacetone alcohol; and organic solvents such as amides such as dimethylformamide. However, the present invention is not limited to such examples. These solvents may be used alone or in combination of two or more. Among the solvents, aliphatic hydrocarbon compounds, alcohols, ethers, esters, ketones and amides are preferable, aliphatic hydrocarbon compounds and esters are more preferable, and n-hexane and ethyl acetate are preferable from the viewpoint of reducing the influence on the human body. Further preferred.
