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:

Fabric treatment agent, textile printing ink set, textile printing method, and textile printed fabric

The pretreatment liquid of the present invention is applicable for a fabric to be used for inkjet textile printing, and the pretreatment liquid contains a block copolymer including a hydrophobic block derived from a hydrophobic resin having an SP value of less than 11 and a hydrophilic block derived from a hydrophilic resin having an SP value of 11 or more, with the difference between the SP values of the hydrophobic resin and the hydrophilic resin of 1.0 or more; and water.

Pretreatment liquid, pretreated fabric and method for producing the same, and image forming method

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.
