Abstract
La presente domanda ha per oggetto un procedimento per l'ottenimento di elementi iniettati presentanti opacità o trasparenza predeterminabile. Tale procedimento comprende una prima fase di miscelazione di un poliuretano termoplastico con coloranti preferibilmente organosolubili seguita da una seconda fase di iniezione termoplastica di tale miscela in uno stampo. Tale procedimento permette di ottenere un elemento iniettato presentante zone a spessore differenziato le quali presentano gradi di opacità o trasparenza differenziati. In particolare i tratti a spessore minore risultano essere trasparenti.Tale procedimento consente quindi di ottenere dei prodotti quali, ad esempio, una pattella per una calzatura in cui si possono evidenziare elementi sottostanti oltre che creare degli effetti di chiaro-scuro.
