Abstract
Provided is a resin molded product having excellent scratch resistance. The resin molded product of the present invention is a resin molded product including a methacrylic-based resin composition, in which the methacrylic-based resin composition contains a (meth)acrylic-based polymer (A) and a fatty acid compound (B), and an absorbance ratio P1/P2 of a peak absorbance P1 in a wave number range of 1630 to 1650 cm−1 to a peak absorbance P2 in a wave number range of 1710 to 1730 cm−1 on a surface of the resin molded product, measured by a single reflection ATR surface reflection method with an infrared spectrophotometer, is 0.0040 or more.

A resin molded product comprising:
- a methacrylic-based resin composition,
- wherein the methacrylic-based resin composition contains a (meth)acrylic-based polymer (A) and a fatty acid compound (B),
- an absorbance ratio P1/P2 of a peak absorbance P1 in a wave number range of 1630 to 1650 cm−1 to a peak absorbance P2 in a wave number range of 1710 to 1730 cm−1 on a surface of the resin molded product, measured by a single reflection ATR surface reflection method with an infrared spectrophotometer, is 0.0040 or more,
- the (meth)acrylic-based polymer (A) includes 70% by mass or more of a repeating unit derived from methyl methacrylate with respect to 100% by mass of a total mass of the (meth)acrylic-based polymer, and
- a content ratio of the fatty acid compound (B) is 1% by mass or more and 10% by mass or less with respect to 100% by mass of a total mass of the methacrylic-based resin composition.
