Abstract

Provided is a pretreatment agent for ink jet textile printing that can provide printed matters on fabric with high color-developing properties and less bleeding. The pretreatment agent includes at least water and (A) a multivalent metal ion and polymer fine particles, (B) a cationic polymer and polymer fine particles, or (C) cationic polymer fine particles.

First claim

1 - 18 . (canceled)

19 . An ink jet textile printing process comprising:
pretreating fabric with a pretreatment agent for ink jet textile printing before printing ink on the fabric, the pretreatment agent comprising: at least water, a cationic polymer including polyallylamine series polymer, a surfactant, and polymer fine particles, wherein the polymer fine particles are an acrylic polymer; the polymer fine particles have a glass transition temperature of −10° C. or less; the polymer fine particles have a mass-average molecular weight of 100000 or more; the polymer fine particles have an acid number of 50 mg KOH/g or less; then printing the ink on the fabric, the polymer fine particles contained in the ink have an acid number of 100 mg KOH/g or less, and the polymer fine particles contained in the ink contain alkyl (meth)acrylate or cyclic alkyl (meth)acrylate as a structural component, wherein the fabric is made of one kind of fiber or blended fiber of two or more selected from the group consisting of cotton, hemp, rayon fiber, acetate fiber, silk, nylon fiber, and polyester fiber.

20 . The ink jet textile printing process according to claim 19 , wherein an ink composition for ink jet textile printing is used in the pretreating.

21 . The ink jet textile printing process according to claim 20 , wherein the ink composition includes a pigment serving as a color material and being self-dispersing or being dispersed in an acrylic resin.

22 . The ink jet textile printing process according to claim 19 , wherein the polymer fine particles have a glass transition temperature of −10° C. or less.

23 . The ink jet textile printing process according to claim 19 , wherein the polymer fine particles have a mass-average molecular weight in the range of about 100,000 to 1,000,000.

24 . The ink jet textile printing process according to claim 19 , wherein the polymer fine particles contain at least one (meth)acrylate as a structural component.

25 . The ink jet textile printing process according to claim 19 , wherein the polymer fine particles contain an acid having carboxyl group as a structural component.

26 . The ink jet textile printing process according to claim 19 , wherein the polyallylamine series polymer includes at least one of polyallylamine, polyallylamine sulfate, polyallylamine hydrochloride, allylamine/diallylamine copolymer, allylamine/diallylamine copolymer sulfate, allylamine/diallylamine copolymer hydrochloride, allylamine dimethylallylamine, allylamine/dimethylallylamine copolymer sulfate, allylamine/dimethylallylamine copolymer hydrochloride, diallylamine, diallylamine sulfate, diallylamine hydrochloride, methyldiallylamine amide, methyldiallylamine amide sulfate, methyldiallylamine amide hydrochloride, diallylamine sulfur dioxide copolymer, diallylamine sulfur dioxide copolymer sulfate, diallylamine sulfur dioxide copolymer hydrochloride, methyl diallylamine sulfur dioxide copolymer, methyldiallylamine sulfur dioxide copolymer sulfate, and methyldiallylamine sulfur dioxide copolymer hydrochloride.

27 . The ink jet textile printing process according to claim 19 , wherein the surfactant comprises acetylene glycol surfactant.

28 . The ink jet textile printing process according to claim 19 , wherein the pretreatment agent further comprises a water-soluble organic solvent that comprises at least one of polyols, amines, monohydric alcohols, alkyl ethers of polyhydric alcohols, 2,2′-thiodiethanol, amides, heterocycles, and acetonitriles.

29 . The ink jet textile printing process according to claim 19 , wherein the pretreatment agent further comprises a water-soluble organic solvent that comprises at least one of polyols and alkyl ethers of polyhydric alcohols.
