Abstract

A treatment liquid composition for ink jet pigment printing is a treatment liquid composition which is used to be adhered to a cloth and which includes a block isocyanate compound, a hydroxyethyl cellulose, and a cationic compound.

First claim

What is claimed is:

1. A treatment liquid composition for ink jet pigment printing to be adhered to a cloth, the treatment liquid composition comprising:
a block isocyanate compound;
a hydroxyethyl cellulose in an amount that ranges between 0.01 to 0.1 % by mass; and
a cationic compound,
wherein the block isocyanate compound includes an aliphatic diisocyanate.

2. The treatment liquid composition for ink jet pigment printing, according to claim 1 ,
wherein the cloth contains fibers having hydroxy groups.

3. The treatment liquid composition for ink jet pigment printing, according to claim 1 ,
wherein the cationic compound contains a polyvalent metal salt or a cationic polymer.

4. The treatment liquid composition for ink jet pigment printing, according to claim 1 ,
wherein the block isocyanate compound is blocked by dimethyl pyrazole or methyl ethyl ketoxime.

5. The treatment liquid composition for ink jet pigment printing, according to claim 1 ,
further comprising cationic or nonionic resin particles.

6. The treatment liquid composition for ink jet pigment printing, according to claim 1 ,
further comprising a surfactant,
wherein the surfactant includes an acetylene glycol-based surfactant having an HLB value of 10 or more.

7. The treatment liquid composition for ink jet pigment printing, according to claim 6 ,
wherein the surfactant has a surface tension of 40 mN/m or more in an aqueous solution at a concentration of 0.1 percent by mass.

8. An ink set comprising:
the treatment liquid composition for ink jet pigment printing according to claim 1 ; and
an ink composition containing a pigment.

9. A recording method comprising:
an adhesion step of adhering the treatment liquid composition for ink jet pigment printing according to claim 1 to a cloth; and
a heating step of heating the cloth obtained in the adhesion step.

10. The recording method according to claim 9 ,
wherein the heating step is a step of heating the cloth at a temperature higher than or equal to a thermal dissociation temperature of the block isocyanate compound.
