摘要

Provided is a tablet for laser printing on which easily recognizable characters can be printed and in which a drug unstable to light can be protected from exposure to laser light. This tablet for laser printing is characterized by comprising a tablet containing a drug that is unstable to light, a first coating layer with which the tablet is coated and which contains a discoloration-inducing oxide, and a second coating layer with which the first coating layer is coated and which contains a discoloration-inducing oxide, the concentration of the discoloration-inducing oxide in the second coating layer differing from the concentration of the discoloration-inducing oxide in the first coating layer. It is preferable that the first coating layer contains 10-50 mass% discoloration-inducing oxide and that the concentration of the discoloration-inducing oxide in the second coating layer is lower than the concentration of the discoloration-inducing oxide in the first coating layer.
