<P>PROBLEM TO BE SOLVED: To provide: a novel cellulose derivative which is a carbon neutral material and which has an excellent solubility in an organic solvent and a high water resistance; a solvent-based adhesive as a novel use of the cellulose derivative; and a resin composition comprising the cellulose derivative which is useful for the solvent-based adhesive. <P>SOLUTION: The cellulose derivative is characterized in that hydrogen atoms of hydroxyl groups contained in the cellulose have at least one group substituted with (A) shown below and at least one group substituted with (B) shown below, and the number-average molecular weight is 1,000-80,000. (A) is a group containing a structure represented by general formula (1). (B) is an acyl group: -CO-R<SB POS="POST">B</SB>(R<SB POS="POST">B</SB>represents a 1C-3C hydrocarbon group). (In general formula (1), n represents 2 or 3, and R<SB POS="POST">A</SB>represents a 1C-3C hydrocarbon group). <P>COPYRIGHT: (C)2012,JPO&INPIT |
