A recording material comprising a transparent support having formed thereon a recording layer containing a thermally coagulatable proteinaceous compound, the recording layer having an average optical density throughout the wavelength region of about 350 nm to 450 nm of at least about 1.5 is disclosed, which is suitable for preparing a reprographic material such as a photomask by flash exposure in heat conducting relation with an original.

Recording material containing a dyed thermally coagulatable

A recording medium is described comprising a recording layer having provided on a support, wherein the recording layer contains at least one chemically modified thermally coagulatable proteinaceous compound containing therein no intermolecular cross-linking bond.
