## Abstract

A resin composition includes a cellulose ester compound and a resin which includes a constituent unit derived from a (meth)acrylic acid ester compound and at least one constituent unit selected from the group consisting of a constituent unit having an epoxy group, a constituent unit having an oxetanyl group, a constituent unit derived from a maleic anhydride compound, and a constituent unit derived from an itaconic anhydride compound. The constituent unit derived from a (meth)acrylic acid ester compound is included in an amount of 40 mass % or greater with respect to a total mass of the resin.

## Claims

### Claim 1

A resin composition comprising:
a cellulose ester compound; and
a resin which includes a constituent unit derived from a (meth)acrylic acid ester compound and at least one constituent unit selected from the group consisting of a constituent unit having an epoxy group, a constituent unit having an oxetanyl group, a constituent unit derived from a maleic anhydride compound, and a constituent unit derived from an itaconic anhydride compound,
wherein the constituent unit derived from a (meth)acrylic acid ester compound is included in an amount of 40 mass % or greater with respect to a total mass of the resin.

### Claim 2 (depends on 1)

The resin composition according to claim 1,
wherein a ratio of the total mass of the resin with respect to a total mass of the cellulose ester compound is 0.05 or greater and 0.6 or less.

### Claim 3 (depends on 1)

The resin composition according to claim 1,
wherein a ratio of the total mass of the resin with respect to a total mass of the cellulose ester compound is 0.1 or greater and 0.5 or less.

### Claim 4 (depends on 1)

The resin composition according to claim 1,
wherein the cellulose ester compound includes at least one selected from the group consisting of cellulose acetate propionate and cellulose acetate butyrate.

### Claim 5 (depends on 1)

The resin composition according to claim 1,
wherein the resin includes a constituent unit derived from at least one compound selected from the group consisting of methyl acrylate, methyl methacrylate, butyl methacrylate, and 2-ethylhexyl methacrylate as the constituent unit derived from a (meth)acrylic acid ester compound.

### Claim 6 (depends on 1)

The resin composition according to claim 1,
wherein the resin includes a constituent unit derived from methyl methacrylate as the constituent unit derived from a (meth)acrylic acid ester compound.

### Claim 7 (depends on 1)

The resin composition according to claim 1,
wherein the resin further includes a constituent unit derived from a styrene compound.

### Claim 8 (depends on 7)

The resin composition according to claim 7,
wherein the constituent unit derived from a styrene compound is included in an amount of 0.5 mass % or greater and 30 mass % or less with respect to the total mass of the resin.

### Claim 9 (depends on 1)

The resin composition according to claim 1,
wherein the resin includes a constituent unit derived from an alkyl (meth)acrylate compound, a constituent unit derived from a maleic anhydride compound, and a constituent unit derived from a styrene compound.

### Claim 10 (depends on 1)

The resin composition according to claim 1,
wherein as the resin, a styrene-methyl methacrylate-maleic anhydride copolymer is included.

### Claim 11 (depends on 1)

The resin composition according to claim 1,
wherein the cellulose ester compound is included in an amount of 60 mass % or greater and 95 mass % or less with respect to a total mass of the resin composition.

### Claim 12 (depends on 1)

A molded article comprising:
the resin composition according to claim 1.
