Colorant-containing solid material and method for manufacturing colorant-containing solid material

A colorant-containing solid material comprising:

• a colorant that is not a pigment;
• and
• a matrix that is formed of a silica and a polysilsesquioxane and covers the colorant, wherein,
• only polymer having a network composed of Si—O—Si is present as a polymer in the matrix and inside the network of Si—O—Si, and
• when an absorption intensity derived from a hydrocarbon group that is not directly bonded to a silicon atom, an absorption intensity derived from a bond between a silicon atom and a non-reactive functional group, and an absorption intensity derived from a bond between a silicon atom and a hydroxy group, determined by an infrared spectroscopic analysis based on a KBr pellet method using a Fourier transform infrared spectrophotometer, are denoted as Ia, Ib, and Ic, respectively, at least one of conditions Ib/Ia≥1.1 and Ib/Ic≥0.6 is satisfied.
