Abstract
Provided is a water-soluble sheet-like coloring material in which sheets are less likely to stick to each other, have appropriate self-standing property and flexibility, and can be quickly brought into a uniform state when dissolved in water. A water-soluble sheet-like coloring material including a film-forming water-soluble polymer; a dissolution accelerator; a colorant; and a moisture-retaining agent.
Claims9
A water-soluble sheet-like coloring material comprising:
- a film-forming water-soluble polymer;
- a dissolution accelerator;
- a colorant;
- and a moisture-retaining agent,
- wherein the film-forming water-soluble polymer is a polysaccharide selected from the group consisting of sodium alginate, pullulan, and cellulose and derivatives thereof;
- and
- the dissolution accelerator is selected from the group consisting of polyvinylalcohol having a polymerization degree of 200 to 1,400, polyvinylpyrrolidone and fatty acid metal salts.

A water-soluble sheet-like coloring material set comprising:
- a combination of
- a first water-soluble sheet coloring material containing a film-forming water-soluble polymer, a dissolution accelerator, a first colorant, and a moisture-retaining agent, and
- a second water-soluble sheet coloring material containing a film-forming water-soluble polymer, a dissolution accelerator, a second colorant, and a moisture-retaining agent,
- wherein the first colorant and the second colorant are different from each other;
- the film-forming water-soluble polymer is a polysaccharide selected from the group consisting of sodium alginate, pullulan, and cellulose and derivatives thereof;
- and
- the dissolution accelerator is selected from the group consisting of polyvinylalcohol having a polymerization degree of 200 to 1,400, polyvinylpyrrolidone and fatty acid metal salts.
