Zusammenfassung:	SE DESCRIBE UNA RESINA QUE INCLUYE UNA MEZCLA DE AL MENOS DOS COMPONENTES POLIMERIZABLES, AL MENOS UN ADITIVO FOTOCROMICO, AL MENOS UN ADITIVO Y AL MENOS UN INICIADOR DE LA POLIMERIZACION. LA MEZCLA DE AL MENOS DOS COMPONENTES POLIMERIZABLES SE SELECCIONA PREFERIBLEMENTE ENTRE ACRILATOS Y METACRILATOS MONOFUNCIONALES, DIFUNCIONALES Y MULTIFUNCIONALES. EL ADITIVO FOTOCROMICO SE SELECCIONA PREFERIBLEMENTE ENTRE ADITIVOS DE ESPIROOXAZINA Y ADITIVOS DE ESPIROPIRANO. EL ADITIVO SE SELECCIONA PREFERIBLEMENTE ENTRE ANTIOXIDANTES, CAPTADORES DE RADICALES Y ABSORBENTES DE ULTRAVIOLETA. A resin is provided comprising a mixture of at least two polymerizable components, at least one photochromic aaditive, at least one additive and at least one polymerization initiator. The mixture of at least two polymerizable components is preferably selected from monofunctional, difunctional and multifunctional acrylates and methacrylates. The photochromic additive is preferably selected from spirooxazine additives and spiropyran additives. And the additive is preferably selected from antioxidants, radical scavengers and ultraviolet absorbers.
