ABSTRACT:
A method for improving the adhesiveness of the surface of a synthetic polymeric substrate to coatings, which comprises coating the surface of the synthetic polymeric substrate with a photopolymerizable composition comprising (A) a hydrophilic resin obtained by the polymerization of a polymerizable unsaturated monomer composition containing at least 10% by weight of a hydrophilic unsaturated monomer, (B) a radical-polymerizable mono-unsaturated monomer and (C) a triplet state sensitizer having a triplet state energy of at least 50 Kcal/mole, and then irradiating actinic rays to the coated surface of the polymeric substrate.
