A cellulose resin composition comprising a cellulose derivative and a lubricant, wherein the cellulose derivative is an acylated cellulose obtained by substituting at least a part of hydrogen atoms of hydroxy groups of a cellulose with an acyl group having 2 to 4 carbon atoms, and the content of the lubricant is in the range of 0.1 to 10% by mass. A cellulose resin composition capable of forming a molded body having a high-quality appearance and scratch resistance is provided.

Cellulose resin composition, molded body and product using same

A cellulose resin composition comprising a cellulose derivative (A) and a lubricant (B), wherein the cellulose derivative (A) is a cellulose derivative obtained by substituting at least a part of hydrogen atoms of hydroxyl groups of a cellulose with a short-chain organic group having 2 to 4 carbon atoms and a long-chain organic group having 8 to 30 carbon atoms with specific degrees of substitution; the lubricant (B) is at least one selected from the group consisting of a urea compound (B1) having a urea group (&#x2014;NH&#x2014;C(&#x2550;O)&#x2014;NH&#x2014;) and an acyclic aliphatic group having 6 to 33 carbon atoms, an amide compound (B2) having an amide group (&#x2014;C(&#x2550;O)&#x2014;NH&#x2014;) and an acyclic aliphatic group having 6 to 33 carbon atoms, a fatty acid metal salt (B3), and a silicone-based lubricant (B4); and a content of the lubricant (B) is in a range of 0.1 to 10% by mass. A cellulose resin composition capable of forming a molded body having a high-quality appearance and scratch resistance is provided.
