| titleOfInvention | PROCEDURE FOR PREPARING PIGMENTED LACQUER OR VARNISHES FOR COLORING CONTACT OR COLORLESS LENSES, COLORLESS OR PIGMENTED LACQUERS SO OBTAINED AND CONTACT LENSES COLORED WITH THEM |
| abstract | PREPARATION OF PIGMENTED LACQUERS OR VARNISHES TO COLOR CONTACT LENSES THAT INCLUDE: A) PREPOLYMERIZATION, BY UV RADIATION OF LAMBDA BETWEEN 375 AND 420 NM, A FRACTION OF A MIXTURE OF: 60-70% N-VINYL-2-PIRROLIDONE; 8 TO 12% OF 2-HYDROXYETHYL METHACRYLATE; 0.3 TO 1% OF CROSSLINERS; UP TO 13% METHACRYLATE OR CYCLLOHEXYL ACRYLATE; 8 TO 15% GLYCIDYL ACRYLATE OR METHACRYLATE AS ADHESIVE; UP TO 1% ACRYLIC OR METHACRYLIC ACID; 0.1 TO 0.5% DI-ISOPROPIL; XANTOGENBISULPHITE, AS A UV PHOTO-INITIATOR, UNDER AGITATION AND ROOM TEMPERATURE UNTIL A MASS OF OLEOSA IS OBTAINED, EU BY CUTTING THE RADIATION AND COOLING ABUSELY BELOW -30 * C IT TRANSFORMS INTO A STORAGE AT LOW TEMPERATURE -25 * - 25 B) EXTRACT THE FREE MONOMERS FROM THE JELLY, AT ROOM TEMPERATURE (15-20 * C) UNTIL FORMING A MALLEABLE PASTE; C) LEAVE TO REST AT ROOM TEMPERATURE, TO LOSE THE FREE MONOMERS CONTAINED BY EXUDATION; D) DISSOLVE THIS PASTE WITH THE MIXTURE OF LIQUID MONOMERS WITHOUT PRE-POLYMERIZING FROM POINT A), AS TO FORM A TEMPERATURE SOLUTION, FILTER AND RECOVER A CLEAR, COLORLESS AND CURABLE LACQUER, WHICH IS PRESERVED BETWEEN -18 AND -25 * C ; E) PIGMENTING THE LACQUER WITH CHOSEN MICRONIZED PIGMENT. |
