摘要:
A process for making a coating layer of a curable composition on a toric surface of an optical article, in particular an ophthalmic lens or lens blank, and in particular a functional coating layer; compositions and apparatus useful for the practice of the process; and products obtained from the practice of the process.
摘要:
The invention concerns a process for forming at least one coating layer on a toric surface of an optical article which comprises: providing an optical article 1 having a toric surface comprising a first principal meridian with a lower radius of curvature r and a second principal meridian with a higher radius of curvature R (r
摘要:
The invention concerns a process for making a coated optical lens blank free of visible fining lines which comprises: (i) providing an optical article having at least one fined but unpolished geometrically defined main face; (ii) providing a mold part having an internal and external surface; (iii) depositing on said main face of said optical article or on the internal surface of the mold part a requisite amount of a liquid curable coating composition; (iv) moving relatively to each other the optical article and the mold part to either bring the coating composition into contact with the main face of the optical article or into contact with the internal face of the mold part; (v) applying pressure to the mold part to spread the liquid curable coating composition on said main face and form a uniform liquid coating composition layer onto the main face; (vi) curing the liquid coating composition layer; (vii) withdrawing the mold part; and (viii) recovering the free of visible fining lines coated optical article.

The invention concerns a process for making a coated optical lens blank free of visible fining lines which comprises: (ix) providing an optical article having at least one fined but unpolished geometrically defined main face; (x) providing a mold part having an internal and external surface; (xi) depositing on said main face of said optical article or on the internal surface of the mold part a requisit amount of a liquid curable coating composition; (xii) moving relatively to each other the optical article and the mold part to either bring the coating composition into contact with the main face of the optical article or into contact with the internal face of the mold part; (xiii) applying pressure to the mold part to spread the liquid curable coating composition on said main face and form a uniform liquid coating composition layer onto the main face; (xiv) curing the liquid coating composition layer; (xv) withdrawing the mold part; and recovering the free of visible fining lines coated optical article.
