PURPOSE: A novel photochromic organic material is provided to use of at least one plasticizer for the preparation of said novel material. The preparation and photochromic articles are constituted wholly or in part by the novel material. CONSTITUTION: A novel photochromic organic material is use of at least one plasticizer for the preparation of the novel material, said preparation and photochromic articles constituted wholly or in part of the novel material. The intervening plasticizer, advantageously a phthalate, is according to a variant simply dispersed in the polymer matrix, or, according to another variant, chemically bound to said polymer matrix. The novel material possesses remarkable photochromic properties together with interesting optical and mechanical properties.
