Composition, cured product and laminate

A method for producing a composition comprising a (meth)allyl group-containing compound and a hydroxy group-containing maleimide compound, the method comprising:

• a step of producing an aromatic amino compound mixture by mixing a (meth)allyl group-containing amino compound represented by formula (6) below and a hydroxy group-containing amino compound represented by formula (9) below;
• and
• a step of maleimidating the aromatic amino compound mixture:
• wherein n1 and m1 are each independently an integer of 1 to 5,
• Aly is a group having a (meth)allyl group represented by formula (7) below,
• B1 is a group having an amino group represented by formula (8) below, and
• A1 is a structure having one or more benzene rings,
• wherein Z1 is a direct bond or a hydrocarbon group having 1 to 10 carbon atoms which may have a substituent, and R1 represents a hydrogen atom or a methyl group,
• —Z2—NH2 (8)
• wherein Z2 is a direct bond or a hydrocarbon group having 1 or 2 carbon atoms which may have a substituent, and R2 and R3 each independently represent a hydrogen atom or a methyl group,
• wherein n2 and m2 are each independently an integer of 1 to 5,
• B2 is a group having an amino group represented by formula (8) above, and
• A2 is a structure having one or more benzene rings.
