Optical article, useful in ophthalmic lens, comprises a transparent optical substrate having a main surface and covering the main surface of substrate, and an anti-fouling coating partially coated with a temporary overlay

Optical article comprises a transparent optical substrate having a main surface and covering the main surface of the substrate, and an anti-fouling coating partially coated with a temporary overlay, where: the anti-fouling coating is obtained by hardening of a polymerizable composition comprises 55-80 wt.%, preferably 60-70 wt.% of a first constituent (A) comprising fluorinated compounds, and 45-20 wt.%, preferably 40-30 wt.% of a second constituent (B) comprising fluorinated linear compounds; and (A) and (B) comprises at least 50%, preferably 60 wt.% of the total coating. Optical article comprises a transparent optical substrate having a main surface and covering the main surface of the substrate, and an anti-fouling coating itself partially coated with a temporary overlay, where: the anti-fouling coating is obtained by hardening of a polymerizable composition comprises 55-80 wt.%, preferably 60-70 wt.% of a first constituent (A) comprising fluorinated compounds, preferably perfluorinated compounds, of which single chain end comprises at least a silanol group or silanol precursor and their mixtures, and 45-20 wt.%, preferably 40-30 wt.% of a second constituent (B) comprising fluorinated linear compounds, preferably perfluorinated compounds, of which two chain ends comprise at least a silanol group or silanol precursor and their mixtures for 100 wt.% of (A) and (B); and (A) and (B) comprises at least 50%, preferably 60 wt.% of the total coating. Article d'optique comprenant un substrat optiquement transparent ayant une surface principale et, recouvrant la surface principale du substrat, un revêtement anti-salissure lui-même au moins partiellement revêtu d'une surcouche temporaire, le revêtement anti-salissure résultant du durcissement d'une composition polymérisable comprenant :- de 55 à 80% en poids d'un premier constituant A choisi parmi les composés fluorés, dont une seule extrémité de chaîne comporte au moins un groupement silanol ou précurseur de silanol et leurs mélanges, et- 45 à 20% en poids d'un second constituant B choisi parmi les composés linéaires fluorés, de préférence perfluorés, dont les deux extrémités de chaîne comportent au moins un groupement silanol ou précurseur de silanol et leurs mélanges, pour 100% en poids du premier constituant A et du second constituant B.- le premier constituant A et le second constituant B représentant ensemble au moins 50% en poids du poids total du revêtement.Application à la lentille ophtalmique.
