Abstract
A light-sensitive recording medium using a photochromic material produced at a low cost, without necessity of fixing free rotation of bonds in its cis compound and removing its trans compound, is disclosed, the recording medium comprising a substrate having thereon a recording layer which contains a photochromic material capable of cis-trans isomerization upon irradiation with light, wherein not more than 50 mol % of the photochromic material has a trans configuration when the recording layer is in a color-disappearing state.
