The present invention relates to poly(aryl ether) polymers which can for example be used in lithographic processes for the photofabrication of three-dimensional (3D) articles. The invention further relates to compositions including these poly(aryl ether) polymers. Still further, the invention relates to lithographic methods to form 3D articles or objects that incorporate the aforementioned polymer compositions.
