Products for Reversacols

Keystone offers a complete range of Reversacol^TM photochromic dyes manufactured by Vivimed Labs Ltd. Vivimed is a world leader in the development of innovative photochromic dyes. These are special dyes that reversibly change color upon exposure to ultraviolet sources, such as sunlight.

Photochromic dyes are largely used in ophthalmic applications, but also used in security and brand protection and in applications such as passports and IDs, banknotes, driving licenses, lottery tickets, gaming cards, tax and postage stamps, admission tickets, vouchers, CDs, DVDs, games, blister foil, and cigarette cartons.

When correctly formulated, the products colored with Reversacol^TM dyes are colorless until exposed to sufficient UV or sunlight. Keystone technical teams are expert in the application and formulation of these dyes and welcome any inquiries related to use of photochromic dye. Please contact your local sales representative for more information regarding the Reversacol^TM photochromic dyes.
