1. An article comprising a holographic recording medium comprising:

  • a binder component comprising at least one thermoplastic;

    a polymerizable component comprising at least one photoactive monomer that is soluble in said binder component, wherein the at least one photoactive monomer is dissolved in said binder component;

    a photoinitiator component comprising at least one photoinitiator that causes said polymerizable component to form a polymer or co-polymer when a portion of said polymerizable component is exposed to a light source; and

    a photoactive component and photobinding receptorswherein said holographic recording medium is capable of recording spatial light distribution via a spatial refractive index change to provide recorded data pages in said holographic recording medium;

    wherein said article behaves as a thermoplastic;

    wherein said article is volatile compound free;

    wherein said article has a melting point at least 10°

    C. greater than room temperature; and

    wherein said article has a thickness greater than 150 μ

    m.
