Document Type and Number:

Japanese Patent JPH0565301

Kind Code:

A

Abstract:

PURPOSE:To obtain the subject derivative excellent in humidity resistance, weathering resistance, etc., and desirable as a coating resin, an adhesive material or the like by reacting a cellulosic material with a specified carbonate compound or an acid chloride.
