An inkjet ink includes an aqueous medium, composite particles, and a cross-linking agent. The composite particles are emulsified particles of a composite of a polyester resin and a disperse dye. The polyester resin includes at least one repeating unit derived from a polyhydric alcohol and at least one repeating unit derived from a polybasic carboxylic acid. The polyester resin is non-crystalline. The polyester resin has a glass transition point of at least 45° C. and no higher than 75° C. The polyester resin has an acid value of at least 10 mgKOH/g and no greater than 70 mgKOH/g. The polyester resin has a hydroxyl value of at least 20 mgKOH/g and no greater than 60 mgKOH/g. The cross-linking agent includes a blocked isocyanate.

In order to satisfy the demand of consumers regarding design attractiveness, an infrared-light-transmitting dark color ink is provided, the ink having a black appearance and attaining high design attractiveness and, despite this, having sufficient infrared-light-transmitting property. The infrared-light-transmitting dark color ink transmits near infrared light having wavelengths of 750-1,500 nm, and comprises a resin component and a pigment component that comprises both a brown pigment, e.g., a benzimidazolone pigment, and a phthalocyanine pigment.
