Aromatic polyamide having good high-temperature resistance and processing ability is obtained by specifying the ratio of storage modulus at the glass transition temperature (Tg).degree.C. to that of (Tg+100).degree.C.

Aromatic polyamide molded article having storage modulus

Disclosed herein is a coating composition which contains a urethane-modified (meth)acrylate compound and a mono(meth)acrylate and is curable upon its exposure to radiation. Also disclosed herein is a coating, especially, a primary coating for an optical fiber, which coating or cladding is composes of a cured material obtained by curing the composition through its exposure to radiation.
