PROBLEM TO BE SOLVED: To provide a coating compsn. for optical articles which can form e.g. an antireflection layer on optical articles, such as lenses, pellicle membranes, or antireflection filters. with good adhesion. SOLUTION: This compsn. contains (a) 100 pts.wt. fluoropolymer having functional groups and fluorine-contg. alicyclic structures in the main chain and (b) 0.1-50 pts.wt. another fluoropolymer having a number average mol.wt. of 1,000-15,000. Pref., the difference in solubility parameter between (a) and (b) is within 2.5 cal/cm<3> . |
