11 Claims

1. A resin-molded body, comprising:

a cellulose acylate (A) selected from cellulose acylate propionate (CAP) and cellulose acylate butyrate (CAB),

a polyester resin (B), and

a cardanol composition (C) containing a cardanol-based compound having a hydroxyl group and a hydroxyl value of 100 mg KOH/g or more;

wherein:

i) the mass ratio (B/A) of the polyester resin (B) to the cellulose acylate (A) is 0.06 or more and 0.5 or less; or

ii) the mass ratio (B/A) of the polyester resin (B) to the cellulose acylate (A) is 0.05 or more and 0.5 or less, the mass ratio (C/A) of the cardanol composition (C) to the cellulose acylate (A) is 0.05 or more and 0.3 or less, at least one of the mass ratios of (B/A) or (C/A) is greater than 0.05; and the mass ratio (C/B) of the cardanol composition (C) to the polyester resin (B) is 0.5 or more and 3 or less; and

wherein the resin-molded body has a tensile modulus of elasticity of 1,470 MPa or more, and a tensile elongation at break of 30% or more.
