An optical recording method comprises the steps of: (A) irradiating a radiation corresponding to a recording information on an optical recording medium having a recording layer containing a diacetylene derivative and at least one selected from the group (hereinafter called the group B) consisting of azulenium salt compounds, pyrylium dyes, diene compounds, croconic methine dyes and polymethine compounds, thereby forming a latent image; and (B) irradiating a radiation on the recording medium having said latent image formed thereon to thereby visualizing said latent image. |
