Crosslinkable, cellulose ester compositions and films formed therefrom

摘要

New compositions for forming films for use in optical devices are provided. The compositions comprise a cellulose and a crosslinking agent dissolved or dispersed in a solvent system. Preferred celluloses are cellulose esters such as cellulose acetates, cellulose triacetates, cellulose acetate phthalates, and cellulose acetate butyrates. Preferred crosslinking agents are triazines such as those derived from melamine and benzoguanamine. The inventive compositions can be used to form, for example, protective and/or compensation films for use in polarizing plates.
