Abstract
A dye is fixed to a solid material by using a diene or dienophile as the dye, incorporating a dienophile or diene into the solid material, effecting Diels-Alder reaction between the diene and the dienophile or between the dye and the solid material for binding the dye to the solid material. The dyed solid material has an increased dye concentration and prevents dye diffusion with the lapse of time.
