Abstract: A polyimide includes a non-crosslinked structure including a main chain. The main chain includes a Si—O—C bond. The main chain may include a C—O—Si—O—C bond. The main chain includes, for example, a group denoted by —OSi(R1)(R2)O—. At least one oxygen atom included in the group bonds to, for example, a carbon atom adjacent to the group to form the Si—O—C bond.

Abstract: A recording medium according to the present disclosure includes a recording layer containing an organic compound having a non-linear optical absorption characteristic. The molar extinction coefficient of the organic compound against light having a wavelength of longer than or equal to 400 nm and shorter than or equal to 405 nm is greater than or equal to 90 mol−1·L·cm−1. In a transient absorption spectrum of the organic compound, an absorbance change ΔAbs at a wavelength of longer than or equal to 400 nm and shorter than or equal to 405 nm is a positive value.
