Abstract
A process for producing colored synthetic resin sheet material having a unicolored or multicolored dye coating applied to one surface thereof and extending into said surface in a uniform manner involves applying a dye-containing material or composition to at least one selective portion of the surface of a synthetic resin sheet material that contains at least one reactive, crosslinkable component, where the dye-containing material is capable of migrating into a non-porous sheet formed of the synthetic resin; controlling the migration of the dye material into the sheet material to a desired depth; and then initiating crosslinking of the crosslinkable component to stop further migration of the dye-containing material.
