Color-Changing Materials And Multiple Component Materials Having A Color-Changing Composition |
摘要 |
The present invention relates to a color-changing material and to a multiple-component material that includes a color-changing composition. The color-changing materials and color-changing compositions are capable of changing color in order to indicate a change in condition, such as a change in pH. The color-changing materials and color-changing compositions include a hydrogel-forming composition, a charged colorant and a pH adjuster. The hydrogel-forming composition includes at least one charged species. |
