Abstract
Revealable substrates and methods include an opacifying layer having a plurality of irregular and/or odd-shaped opaque polymer particles defining voids therebetween. At least part of the opacifying layer may be induced to become transparent, for example, by collapsing at least some of the voids to reduce or eliminate internal reflection of light in the opacifying layer. Upon rendering transparent the portion(s) of the opacifying layer, a color material (e.g., ink) disposed underneath the opacifying layer is revealed and/or viewable therethrough.
Claims20
A thermal and/or pressure reveal substrate comprising:
- a layer of opacifying material;
- color material disposed on a first side of the layer of opacifying material;
- wherein the layer of opacifying material covers the color material,
- wherein the opacifying material, in an opaque state, comprises a plurality of irregular and/or odd-shaped opaque polymer particles defining voids therebetween and having different shapes and/or different sizes, and
- further wherein the opacifying material is configured to, upon application of sufficient temperature and/or pressure, change from the opaque state to a transparent state to reveal the color material underneath the opacifying material.
2 more elements
A method comprising:
- providing a color material covered with a layer of opacifying material in an opaque state such that the opacifying material impedes visibility of the color material through the opacifying material;
- and
- changing at least a portion of the layer of opacifying material from an opaque state to a transparent state to reveal the color material underneath the opacifying material, and
- wherein the layer of opacifying material, in the opaque state, comprises a plurality of irregular and/or odd-shaped opaque polymer particles having voids therebetween and different shapes and/or different sizes.
