Abstract

The object is to provide a transfer paper having good image deterioration resistance, color development property and adhesion property. The object is achieved by a transfer paper for use in a transfer textile printing method using sublimation textile ink, which comprises a base paper and one or more coating layer(s) provided on at least one side of the base paper, wherein an outermost coating layer positioned on the outermost side with respect to the base paper contains at least a pigment and a binder, at least one of the pigment is amorphous silica, and the binder contains two or more different binders, and at least one of the binders is an ethylene-vinyl acetate copolymer.

Claims (21)

1. A transfer paper for use in a transfer textile printing method using sublimation textile ink, which comprises a base paper and one or more coating layer(s) provided on at least one side of the base paper, wherein,

an outermost coating layer positioned on the outermost side with respect to the base paper contains at least a pigment and a binder,

at least one of the pigment is amorphous silica,

the binder contains two or more different binders, and at least one of the binders is an ethylene-vinyl acetate copolymer, and

the base paper contains a filler, and at least one of the filler is calcined kaolin,

a content of the calcined kaolin in the base paper is 10 parts by mass or more and 20 parts by mass or less based on 100 parts by mass of pulp in the base paper.

2. A transfer paper for use in a transfer textile printing method using sublimation textile ink, which comprises a base paper and one or more coating layer(s) provided on at least one side of the base paper, wherein,

an outermost coating layer positioned on the outermost side with respect to the base paper contains at least one pigment and two or more different binders,

the at least one pigment contains amorphous silica, and the two or more different binders contain an ethylene-vinyl acetate copolymer, and

the base paper contains at least one filler, and the at least one filler is calcined kaolin,

a content of the calcined kaolin in the base paper is 10 parts by mass or more and 20 parts by mass or less based on 100 parts by mass of pulp in the base paper.

3. The transfer paper according to claim 1 , wherein a glass transition temperature of the ethylene-vinyl acetate copolymer is more than 0° C.

4. The transfer paper according to claim 1 , wherein the ethylene-vinyl acetate copolymer has an average particle diameter of 0.08 μm or more and 0.3 μm or less.

5. The transfer paper according to claim 1 , wherein the binder contains two or more different binders, at least two of which are an ethylene-vinyl acetate copolymer and a silanol-modified polyvinyl alcohol.

6. The transfer paper according to claim 2 , wherein the two or more different binders contain an ethylene-vinyl acetate copolymer and a silanol-modified polyvinyl alcohol.

7. The transfer paper according to claim 1 , wherein the base paper is an acidic paper.

8. The transfer paper according to claim 2 , wherein a glass transition temperature of the ethylene-vinyl acetate copolymer is more than 0° C.

9. The transfer paper according to claim 2 , wherein the ethylene-vinyl acetate copolymer has an average particle diameter of 0.08 μm or more and 0.3 μm or less.

10. The transfer paper according to claim 2 , wherein the base paper is an acidic paper.

11. The transfer paper according to claim 3 , wherein the binder contains two or more different binders, at least two of which are an ethylene-vinyl acetate copolymer and a silanol-modified polyvinyl alcohol.

12. The transfer paper according to claim 8 , wherein the two or more different binders contain an ethylene-vinyl acetate copolymer and a silanol-modified polyvinyl alcohol.
