Abstract

A three-dimension forming support material for ink jet includes a warm water-soluble radiation curable compound that exhibits solubility in warm water of at least 40° C. to 90° C. after the compound is cured; and at least one polyglycerin compound selected from the group consisting of fatty acid esters of polyglycerin, ethylene oxide adducts of polyglycerin, and propylene oxide adducts of polyglycerin.

First claim

What is claimed is:

1 . A three-dimension forming support material for ink jet, comprising:
a warm water-soluble radiation curable compound that exhibits solubility in warm water of at least 40° C. to 90° C. after the compound is cured; and at least one polyglycerin compound selected from the group consisting of fatty acid esters of polyglycerin, ethylene oxide adducts of polyglycerin, and propylene oxide adducts of polyglycerin.

2 . The three-dimension forming support material for ink jet according to claim 1 ,
wherein a viscosity at 23° C. of the warm water-soluble radiation curable compound is from 5 mPa·s to 80 mPa·s.

3 . The three-dimension forming support material for ink jet according to claim 1 ,
wherein a content of the warm water-soluble radiation curable compound is from 40% by weight to 80% by weight with respect to a total amount of the three-dimension forming support material.

4 . The three-dimension forming support material for ink jet according to claim 1 ,
wherein the polyglycerin compound is a polymer composed of 2 molecules to 20 molecules of glycerin.

5 . The three-dimension forming support material for ink jet according to claim 1 ,
wherein a hydrophile lipophile balance (HLB) value of the at least one polyglycerin compound is from 7 to 13.

6 . The three-dimension forming support material for ink jet according to claim 1 ,
wherein the polyglycerin compound is solid at 23° C.

7 . The three-dimension forming support material for ink jet according to claim 1 ,
wherein a melting temperature of the polyglycerin compound is from 40° C. to 70° C.

8 . The three-dimension forming support material for ink jet according to claim 1 ,
wherein a total content of the polyglycerin compound contained in the three-dimension forming support material is from 5% by weight to 45% by weight with respect to a total amount of the three-dimension forming support material.

9 . The three-dimension forming support material according to claim 1 , further comprising a plasticizer.

10 . The three-dimension forming support material according to claim 9 ,
wherein the plasticizer includes at least one selected from the group consisting of polyether polyol, castol oil polyol, and polyester polyol.

11 . The three-dimension forming support material according to claim 10 ,
wherein a hydroxyl value of the castol oil polyol is from 100 mgKOH/g to 300 mgKOH/g.

12 . The three-dimension forming support material according to claim 9 ,
wherein a content of the plasticizer is 25% by weight to 60% by weight with respect to a total amount of the three-dimension forming support material.

13 . The three-dimension forming support material according to claim 1 ,
wherein the warm water-soluble radiation curable compound includes at least one selected from the group consisting of hydroxyethyl (meth)acrylate, (meth)acrylamide, (meth)acryloyl morpholine, acrylic acid, methoxy triethylene glycol acrylate, and methoxy polyethylene glycol acrylate.

14 . The three-dimension forming support material according to claim 13 ,
wherein the warm water-soluble radiation curable compound includes hydroxyethyl (meth)acrylate.

15 . The three-dimension forming support material according to claim 1 , further comprising a non-radiation curable component.

16 . The three-dimension forming support material according to claim 15 ,
wherein a weight average molecular weight of the non-radiation curable component is from 200 to 1,000.

17 . The three-dimension forming support material according to claim 15 ,
wherein a viscosity at 25° C. of the non-radiation curable component is 200 mPa·s or less.

18 . The three-dimension forming support material according to claim 15 ,
wherein the non-radiation curable component is composed of a fatty acid ester having carbon atoms of 16 to 20.

19 . A three-dimension forming support material cartridge accommodating the three-dimension forming support material according to claim 1 .

20 . A three-dimension forming composition set comprising a radiation curable three-dimension forming material and the three-dimension forming support material according to claim 1 .
