Werner-type chromium compounds as laminating and coating compositions

Claim 1

A LAMINATED ARTICLE WITH LAMINAE OF GLASS BONDED WITH AN ETHYLENIC POLYMER AND A COMPLEX COMPOUND OF THE WERNER TYPE CONSISTING OF AN ACRYLIC FUNCTIONAL ACIDO GROUP MADE UP OF A CARBOXYL RADICAL JOINED TO AN ALPHA, BETA-UNSATURATED CARBON CHAIN CONTAINING FROM TWO TO SIX CARBON ATOMS, THE ACIDO GROUP BEING COORDINATED, THROUGH THE CARBOXYL RADICAL, WITH A NUCLEAR TRIVALENT CHROMIUM ATOM, THE COMPLEX ALSO CONTAINING ADDITIONAL COORDINATED NUCLEAR TRIVALENT CHROMIUM, THE VALENCE AND COORDINATION POSITIONS OF ALL THE NUCLEAR CHROMIUM ATOMS, OTHER THAN THOSE POSITIONS OCCUPIED BY COORDINATED FUNCTIONAL ACIDO GROUPS, BEING OCCUPIED BY GROUPS SELECTED FROM THE CLASS CONSISTING OF AQUO GROUPS, HYDROXYL, AND MONOVALENT NEGATIVE GROUPS WHICH ARE ANIONS OF MONOBASIC ACIDS, AND THE TOTAL NUMBER OF NUCLEAR TRIVALENT CHROMIUM ATOMS WITHIN THE COMPLEX BEING ABOUT TWO TIMES THE NUMBER OF COORDINATED FUNCTIONAL ACIDO GROUPS.
