CORROSION INHIBITOR APPLIED TO THE BACK OF A MIRROR IN THE FORM OF A PROTECTIVE COAT CONTAINING IMINODIACETONITRILE.

摘要

A composition for inhibiting corrosion of the metal film on the back of the mirrors comprising a fluid organic resin coating system capable of being applied as a film and hardened to form a protective layer on said metal film, said resin system comprising a resin organic and a corrosion inhibitor in an amount, by weight, of about 0.01 to 20% represented by the formula: in which the radicals R1, R2, R3 and R4 can be identical or different from each other and are hydrogen, an aliphatic, cycloaliphatic, araliphatic or aromatic radical, and can be substituted or unsubstituted; A is hydrogen or CZ-CR5R6CN; X, Y and Z are independently selected from 0 5; and R5 and R6 are defined as previously done with R1, R2, R3 and R4.
