Abstract

See full text

A method of manufacturing an optical article (10) includes supplying a first coating composition (A) and supplying one or more additional coating compositions (B) to an ultrasonic discharge nozzle (102) of a coating apparatus (100). At least one of the first coating composition (A) and the one or more additional coating compositions (B) is a photochromic coating composition. The method includes mixing the first coating composition and the one or more additional coating compositions at the ultrasonic discharge nozzle (102) of the coating apparatus (100), and applying the mixture (C) of the first coating composition (A) and the one or more additional coating compositions (B) to at least a portion of the optical article (10) so as to provide a pattern (24) on the optical article upon exposure to actinic radiation. The mixture (C) of the first coating composition (A) and the one or more additional coating compositions (B) is applied from the ultrasonic discharge nozzle (102) as a controlled, predetermined pattern of atomized droplets.
