Abstract

There is provided with a modification method. Ultraviolet rays are irradiated on part of a surface of a resin article, so as to selectively modify the part of the surface of the resin article such that an electroless plating layer will be deposited. The ultraviolet rays are irradiated such that an interference pattern by the ultraviolet rays is formed on the surface of the resin article.

First claim

What is claimed is:

1 . A modification method comprising:
irradiating ultraviolet rays on part of a surface of a resin article, so as to selectively modify the part of the surface of the resin article such that an electroless plating layer will be deposited, wherein the ultraviolet rays are irradiated such that an interference pattern by the ultraviolet rays is formed on the surface of the resin article.

2 . The modification method according to claim 1 , wherein in the irradiating, the ultraviolet rays are irradiated on the part of the surface of the resin article through a shielding member having a UV-transmissive portion, and
the interference pattern is formed by ultraviolet rays which come through the UV-transmissive portion.

3 . A modification method comprising:
irradiating ultraviolet rays on part of a surface of a resin article through a shielding member having a UV-transmissive portion so as to selectively modify the part of the surface of the resin article such that an electroless plating layer is deposited, wherein the shielding member condenses ultraviolet rays which go through the shielding member.

4 . The modification method according to claim 2 , wherein the UV-transmissive portion is a slit.

5 . The modification method according to claim 4 , wherein the width of the slit is larger than the width of the part of the surface of the resin article to be modified such that an electroless plating layer is deposited.

6 . The modification method according to claim 4 , wherein an region on the surface of the resin article irradiated by ultraviolet rays which come through the slit has a striped pattern.

7 . The modification method according to claim 2 , wherein the UV-transmissive portion is a diffraction grating.

8 . The modification method according to claim 2 , wherein the ultraviolet rays are irradiated on the surface of the resin article by scanning the surface of the resin article with ultraviolet rays having a linear irradiation area through the shielding member.

9 . The modification method according to claim 1 , wherein irradiation of the ultraviolet rays is performed in an atmosphere that contains at least one of oxygen or ozone.

10 . The modification method according to claim 1 , wherein the ultraviolet rays are an ultraviolet ray laser beam having a wavelength of 243 nm or less.

11 . The modification method according to claim 10 , wherein in the irradiating, after irradiating the ultraviolet ray laser beam, a further modifying treatment is performed on a region encompassing the part of the surface of the resin article.

12 . The modification method according to claim 11 , wherein the further modifying treatment is to irradiate ultraviolet rays having a wavelength of 243 nm or less on a region encompassing the part of the surface of the resin article using an ultraviolet ray lamp or an ultraviolet ray LED, in an atmosphere that contains at least one of oxygen or ozone.

13 . The modification method according to claim 1 , wherein the surface of the resin article includes at least one of polyolefin, polyester, polyvinyl, polycarbonate, or polyimide.

14 . A method for manufacturing a resin article having a plating layer, the method comprising:
selectively modifying part of a surface of a resin article by irradiating ultraviolet rays on the part of the surface of the resin article, the ultraviolet rays being irradiated such that an interference pattern by the ultraviolet rays is formed on the surface of the resin article; and forming a plating layer on the part of the surface of the resin article by electroless plating.

15 . A resin article having a plating layer that was manufactured according to a method comprising:
selectively modifying part of a surface of a resin article by irradiating ultraviolet rays on the part of the surface of the resin article, the ultraviolet rays being irradiated such that an interference pattern by the ultraviolet rays is formed on the surface of the resin article; and forming a plating layer on the part of the surface of the resin article by electroless plating.
