PROCESS FOR MAKING A NON-POLAR POLYMERIC MATERIAL DYEABLE WITH AN ACID DYE

摘要

63293-2781 Process for making a surface of a non-polar polymeric material dyeable with an acid dye which comprises the treatment of said surface with a low temperature microwave plasma from a chemical compound which is capable of creating receptor sites for acid dye on said surface. There is also disclosed non-polar polymeric material which has been made dyeable with an acid dye using the above process, a process for dyeing non polymeric material with an acid dye and non-polar polymeric material which has been dyed using the latter process.
