摘要： The purpose of the present invention is to provide an actinic radiation curable inkjet ink which has less color mixing, which can obtain white ink with fewer surface irregularities and excellent smoothness, which has excellent actinic radiation transmittance and curability, and which enables sol-gel phase transition by temperature change, and to provide an inkjet image forming method, and a recording medium on which an image has been formed using the inkjet ink. This purpose is achieved by an actinic radiation curable inkjet ink that contains a photopolymerizable compound, a photo initiator, a gelling agent, and a white pigment, wherein the white pigment contains titanium oxide, the gelling agent contains at least one type of gelling agent A that contains an alkyl chain comprising a straight chain portion with 12-26 carbon atoms, wherein the content of the gelling agent A is 5-35 mass % of the content of the titanium oxide.

摘要： A fabric treatment agent that is used in textile printing with a sublimable color material includes a color-material scavenging compound having an Rf value of 0.7 or less according to paper chromatography performed under following conditions. In Procedure 1, cellulose filter paper is impregnated with a 10% solution of the color-material scavenging compound and then dried to prepare a carrier. In Procedure 2, a 0.1% solution of a sublimable color material in tetrahydrofuran is spotted on the carrier and then dried to prepare a development sample. In Procedure 3, the development sample is developed using acetonitrile as a solvent for 3 minutes at 25° C. In Procedure 4, the Rf value is calculated by a following formula: R f = ( distance travelled by the sublimable color material ) ( distance travelled by acetonitrile ) .
