Abstract
Official abstract text for this publication.
A laminate has an electromagnetic wave transmissivity. The laminate includes a substrate made of a synthetic resin and a colored layer laminated on the substrate. The relative permittivity of the colored layer is in a range of 3.1 to 66.7. The effective permittivity of the laminate is greater than the relative permittivity of the substrate and 3.0 or less.
First claim
Opening claim text (preview).
What is claimed is: 1 . An electromagnetic wave transmissive laminate having electromagnetic wave transmissivity, comprising: a substrate made of a synthetic resin; and a colored layer laminated on the substrate, wherein a relative permittivity of the colored layer is in a range of 3.1 to 66.7, and an effective permittivity of the laminate is greater than a relative permittivity of the substrate and 3.0 or less. 2 . The electromagnetic wave transmissive laminate according to claim 1 , wherein a primer layer is laminated on the substrate, and the colored layer is laminated on the primer layer.
