Abstract
An ink composition includes a first saccharide and a second saccharide. The first saccharide is a linear saccharide having 4 or more saccharide units and the second saccharide is at least one selected from the group consisting of trehalose, maltotriose, and a cyclic saccharide.
Claims9
An ink composition comprising:
- a first saccharide;
- a second saccharide,
- wherein:
- the first saccharide is a linear saccharide having 4 or more saccharide unit;
- the second saccharide is a cyclic saccharide comprising a methylated β-cyclodextrin;
- and
- the ratio of a first saccharide content to a second saccharide content is in the range of about 3:1 to about 1:3;
- and
- a solid humectant which is solid at 20° C. and a relative humidity of 60%, wherein:
- the solid humectant contains at least one selected from the group consisting of a first solid humectant and a second solid humectant;
- the first solid humectant is at least one selected from the group consisting of trehalose, isotrehalose, neotrehalose, and mannitol;
- and
- the second solid humectant is at least one selected from the group consisting of maltotriose, maltotetraose, and maltopentaose.
