    Abstract: A color filter including a substrate and colored parts formed on the substrate. The substrate has a surface having rectangular unit regions defined by evenly dividing the surface along a first direction and a second direction orthogonal to the first direction. Each of the rectangular unit regions has four rectangular sub-regions which are three colored regions and one uncolored region. A first colored region has a first boundary with the uncolored region and a second boundary with a second colored region. A first colored part is formed in the first colored region with a first gap being formed in the first direction between the first boundary and a side of the first colored part facing the first boundary, and with a second gap greater than the first gap being formed in the second direction between the second boundary and a side of the first colored part facing the second boundary.

    Abstract: A steam-releasing pouch includes two laminated sheets forming an accommodation compartment that accommodates a content, a sealing portion that seals the two sheets to form an opening that opens part of the accommodation compartment, and a steam-releasing sealing portion formed in the sealing portion to open as pressure of the accommodation compartment increases in a state in which the opening is sealed. The steam-releasing sealing portion includes a first sealant layer having at least a first base layer that faces the accommodation compartment and a second base layer laminated with the first base layer and a second sealant layer having at least a third base layer that faces the accommodation compartment and a fourth base layer laminated with the third base layer. The first base layer and the third base layer are joined together.

    Abstract: A decorative sheet comprises a transparent resin layer containing a polyolefin-based resin, and a surface protective layer containing a thermosetting resin and provided on a front surface side of the transparent resin layer. Further, an uneven pattern is provided on a front surface of the surface protective layer. A percentage of a surface waviness of the decorative sheet after molding to a surface waviness of the decorative sheet before molding, which is defined as a residual embossing ratio, is 30% or more; and an absolute value of a difference between a gloss of a surface of the decorative sheet before molding and a gloss of the surface of the decorative sheet after molding, which is defined as a gloss difference, is less than 5%.

    Abstract: A package substrate that prevents breakage of a core substrate is provided. A package substrate includes a core substrate made of a brittle material, at least one insulating layer formed on one surface or both surfaces of the core substrate, and one or more wiring layers formed on the insulating layer and/or in the insulating layer, the core substrate being exposed from an outer peripheral portion of the insulating layer, and the insulating layer being chamfered.

    Abstract: There is provided an optical element for counterfeit prevention that has both high counterfeit preventing property and designability by a multi-optical element structure. The optical element has a second layer (3) having a relief structure on a front surface, a first layer (2) disposed on the second layer (3), and a third layer (6) in a thin film interposed between the second layer (3) and the first layer (2) and formed along a front surface of the relief structure. The second layer (3) has a refractive index lower than a refractive index of the first layer (2) and the third layer (6) has a refractive index higher than the refractive index of the first layer (2). The optical element has at least a first region (4) and a second region (5) in a plan view. In the first region (4), an electromagnetic wave that enters from a side of the first layer (2) in a specific angle range is configured to be totally reflected. In the second region (5), a relief structure that causes at least one of diffraction, interference, scattering, refraction, and absorption of an electromagnetic wave is disposed and the electromagnetic wave entering from the first layer (2) side is configured to be reflected by a refractive index difference between the first layer (2) and the third layer (6).
