Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
52 words
A method of improving adhesive property of plastic supports which comprises coating the plastic support on the surface with an aqueous liquid containing a hydrophilic polymer and hydrogen peroxide and irradiating the coated surface with ultraviolet rays while keeping said coated surface in its wet state where the hydrogen peroxide is present.
Claim 2
Independent Claim
52 words
A method of improving adhesive property of plastic supports which comprises coating the plastic support on the surface with an aqueous liquid containing a hydrophilic polymer and hydrogen peroxide and irradiating the coated surface with ultraviolet rays while keeping said coated surface in its wet state where the hydrogen peroxide is present.
Claim 3
Dependent Claim
17 words
A plastic support produced by using the method of claim 1, said support having improved adhesive property.
