Abstract

La présente invention porte sur un procédé pour produire un film optique qui comprend une résine acrylique et une résine d'ester de cellulose qui vérifient les équations 2,3 ≤ X+Y ≤ 2,6 et 1,4 ≤ X ≤ 2,6, ou un film optique qui comprend une résine d'ester de cellulose dans laquelle le degré de substitution d'un groupe acétyle dans un fragment ester de cellulose est 2,0 à 2,5, ledit procédé étant caractérisé en ce que la production s'effectue par un processus de formation de film coulé dans un solvant en utilisant un activant qui a une teneur en eau de 2,0 à 5,0 % en masse pendant une période allant du déclenchement de la production jusqu'à un temps d'élévation durant lequel un fonctionnement en régime permanent est déclenché et qui a une teneur en eau de 0,6 à 2,0 % en masse pendant une période durant laquelle le fonctionnement en régime permanent se produit.
