Polymerizable composition and decorative film

A polymerizable composition comprising:

• a liquid crystal compound represented by Formula (1);
• and
• a chiral compound,
• wherein a proportion of a total amount of a compound including one polymerizable group is 60% by mass or more with respect to a total amount of a compound including at least one polymerizable group,
• in Formula (1), R1 to R4 each independently represent a hydrogen atom, an alkyl group having 1 to 20 carbon atoms, a group having a structure in which at least one —CH2— in an alkyl group having 2 to 20 carbon atoms is substituted with —O—, —S—, —NH—, —N(CH3)—, —C(═O)—, —OC(═O)—, or —C(═O)O—, or —CN,
• where at least one of R2, R3, or R4 is a substituent which is not a hydrogen atom,
• L1 and L2 each independently represent a single bond, —COO—, —OCO—, —CH═CH—COO—, —OCO—CH═CH—, —CH═C(CN)—COO—, —OCO—C(CN)═CH—, —CH═CH—CO—, —CO—CH═CH—, —CH═N—, —N═CH—, —CO—NH—, —NH—CO—, —CH2O—, —OCH2—, —CH2—CH2—O—, —OCH2—CH2—, —O—, —S—, —CO—, —CH═CH—, or —C≡C—,
• Sp1 represents a single bond, an alkylene group having 1 to 20 carbon atoms, or a group having a structure in which at least one —CH2— in an alkylene group having 2 to 20 carbon atoms is substituted with —O—, —S—, —NH—, —N(CH3)—, —C(═O)—, —OC(═O)—, or —C(═O)O—, and
• P1 represents a polymerizable group represented by Formula (P-1) or Formula (P-2),
• in Formula (P-1) and Formula (P-2), * represents a bonding position.
