Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
81 words
In a thermal recording element having formed on a support a recording layer which yields an image on thermal deformation under high intensity irradiation due to a difference in optical density between irradiated areas and non-irradiated areas and a protective layer containing an organic high molecular weight material formed on the recording layer, the improvement wherein a higher fatty acid having more than 10 carbon atoms or the higher fatty acid amide thereof is present in or on the protective layer.
Claim 2
Dependent Claim
81 words
In a thermal recording element having formed on a support a recording layer which yields an image on thermal deformation under high intensity irradiation due to a difference in optical density between irradiated areas and non-irradiated areas and a protective layer containing an organic high molecular weight material formed on the recording layer, the improvement wherein a higher fatty acid having more than 10 carbon atoms or the higher fatty acid amide thereof is present in or on the protective layer.
