点を有する。BACKGROUND OF THE INVENTION Transparent copolyamides obtained from isophthalic acid and/or terephthalic acid, a cycloaliphatic diamine and hexamethylene diamine have been known for a long time. For example, Japanese Patent Publication No. 46-41024 discloses a method for producing a quaternary copolyamide obtained from isophthalic acid, terephthalic acid, bis(4-aminocyclohexyl)methane, and hexamethylene diamine. Such copolyamides have excellent transparency, have a high glass transition temperature, and therefore have excellent heat resistance, and have the advantage that changes in dimensions and physical properties due to water absorption are extremely small.

This has hindered the wide application of such copolyamides.

でいた。[0004] Alcohol resistance is a very important property, especially when used as eyeglass frames, since alcohol is often contained in hair styling products and the like. Although the copolyamide obtained from isophthalic acid and/or terephthalic acid, alicyclic diamine, and hexamethylene diamine has excellent basic properties as an eyeglass frame as mentioned above, it has poor alcohol resistance, so it is not suitable for eyeglass frames. Its application as such had not been realized.
