Resin molded product and vehicle part
A resin molded product includes: a laminated body including a transparent resin layer that constitutes a transparent resin substrate molded in a predetermined shape, and a metal evaporation film formed on a surface of the transparent resin layer; and a colored layer formed on one surface of the laminated body and configured to transmit infrared rays. The laminated body includes a region where the metal evaporation film is removed by an irradiation with an infrared laser beam.
1. A resin molded product comprising:
a laminated body including a colorless and transparent resin layer that constitutes a colorless and transparent resin substrate molded in a predetermined shape, and a metal evaporation film formed on a first surface of the colorless and transparent resin layer;
a colored layer continuously formed on one entire surface of the laminated body and configured to transmit infrared rays; and
a light guide lens made of a transparent resin material and continuously formed on one entire surface of the colored layer,
wherein the laminated body includes a region where the metal evaporation film is removed by an irradiation with an infrared laser beam,
the colored layer is formed on a second surface of the colorless and transparent resin layer opposite to the first surface of the colorless and transparent resin layer on which the metal evaporation film is formed,
the metal evaporation film is in direct contact with the colorless and transparent resin layer, the colored layer is in direct contact with the colorless and transparent resin layer, and the light guide lens is in direct contact with the colored layer,
the colored layer is made of an acrylic urethane resin paint including a black pigment, and
a plurality of reflective steps is formed at a predetermined interval on a fourth surface of the light guide lens opposite to a third surface of the light guide lens on which the colored layer is formed.
2. A vehicle part comprising the resin molded product according to claim 1 .
3. The resin molded product according to claim 1 , wherein the colored layer has a spectral transmittance of 50% or more with respect to the infrared laser beam.
4. The resin molded product according to claim 1 , wherein a width of the region is 0.1 mm or more.
5. The resin molded product according to claim 1 , wherein a thickness of the metal evaporation film is about 20 nm to 150 nm.
6. The resin molded product according to claim 1 , wherein a thickness of the colored layer is about 5 μm to 10 μm.
