Abstract
A printing material comprises a shaped structure made of a combustible material and an oxidizing agent, or a self-combustible material having an oxidizing agent contained therein, or a mixture of a self-combustible material and a combustible material. The printing material is formed with pits by application of a laser beam with small output power. The printing material may further comprise a light absorber in order to promote absorption of the laser beam in the printing material.
