Claims30
An image recording coating comprising:
- a substrate having a layer disposed thereon, wherein the layer includes:
- a matrix;
- a radiation absorbing compound;
- an inorganic acid or salt thereof, wherein the inorganic acid or salt thereof comprises an inorganic phosphonium acid or salt thereof;
- and
- a reactant compound, wherein the reactant compound is selected from one the following:
- camphor, phenyglycinol, chilesterol, and combinations thereof, wherein the radiation absorbing compound absorbs radiation and initiates a reduction/oxidation reaction between the inorganic acid or salts thereof and the reactant compound to produce a color change.

A method for preparing an image recording medium, the method comprising:
- providing a matrix;
- a radiation absorbing compound, an inorganic acid or salt thereof, and a reactant compound, wherein the inorganic acid or salt thereof is selected from one the following:
- phosphomolybdic acids or salts thereof, phosphovanadic acids or salts thereof, and combinations thereof, wherein the radiation absorbing compound absorbs radiation and initiates a reduction/oxidation reaction between the inorganic acid or salts thereof and the reactant compound to produce a color change;
- dissolving the radiation absorbing compound, the inorganic acid or salt thereof, and the reactant compound, in the matrix to form a matrix mixture;
- and
- disposing the matrix mixture onto a substrate.

An image recording coating comprising:
- a substrate having a layer disposed thereon, wherein the layer includes:
- a matrix, wherein the matrix includes a color former and an activator;
- a radiation absorbing compound;
- an inorganic acid or salt thereof, wherein the inorganic acid or salt thereof comprises an inorganic phosphonium acid or salt thereof;
- and
- a reactant compound, wherein the radiation absorbing compound absorbs radiation and initiates a reduction/oxidation reaction between the inorganic acid or salts thereof and the reactant compound to produce a color change.

An image recording coating comprising:
- a substrate having a layer disposed thereon, wherein the layer includes:
- a matrix, wherein the matrix includes a color former and an activator;
- a radiation absorbing compound;
- an inorganic acid or salt thereof;
- and
- a reactant compound, wherein the reactant compound includes an alpha amino alcohols containing NH2C(R1,R2)CH2OH, wherein R1 and R2 each independently selected from the following:
- hydrogen, aryl, and alkyl groups, wherein the radiation absorbing compound absorbs radiation and initiates a reduction/oxidation reaction between the inorganic acid or salts thereof and the reactant compound to produce a color change.
