ABSTRACT:
A treating method for imparting hydrophilic property to the surface of a hydrophobic polymer substrate comprising the step of: contacting the surface of the polymer substrate having carbon atoms bonded with a single hydrogen atom in the molecule with a radically polymerizable compound and then irradiating actinic rays to the polymer substrate coated with the polymerizable compound. The homopolymer of the above polymerizable compound is soluble and/or swellable in water or in electrolytic solutions. If desired, the polymerizable compound may be mixed with a triplet state sensitizer having triplet state energy of 50 Kcal/mol or more or photosensitizer which produces free radicals by irradiation.
