An anti-fogging agent contains silica particles and a solvent, and a regression coefficient 4050 to 100 of a regression line obtained from contact angles measured at from a lapse of 50 seconds to a lapse of 100 seconds and an elapsed time is smaller than 0 when the contact angles are measured using a contact angle meter according to the following condition A: condition A: in an environment of 25 C. and 65% RH, 0.5 L of the anti-fogging agent is dropped onto a PTFE substrate, a moment when the anti-fogging agent comes into contact with the PTFE substrate is taken as 0 seconds, and the contact angle is measured every 5 seconds.

A dia for an automotive dia projection system has a transparent substrate with an opaque coating in portions thereof, thereby forming a binary pattern for projection. The pattern features a dither noise microstructure, such that an associated image is projectable giving the perception of a greyscale image to the human viewer.

Vehicle fenders for vehicles include a side turn indicator. A vehicle fender may include a recess portion, and the side turn indicator, including a light source, may be disposed in the recessed portion. The vehicle fender may hide, or otherwise obscure, the light source when the side turn indicator in an inactive mode (e.g., not illuminated). However, when the light source is in an active mode (e.g., the side turn indicator is illuminated), light from the light source is visible through any structure of the side turn indicator and the side turn indicator is visible to present an indication to which the vehicle may turn. Further, the side turn indicator, when illuminated, is generally no longer hidden/obscured by the vehicle fender.

The lighting device disclosed at an embodiment of the invention includes a substrate; a first reflective layer disposed on the substrate and having a plurality of reflection patterns; a light source disposed on the substrate; a resin layer disposed on the first reflective layer, and a second reflective layer disposed on the resin layer and having a plurality of holes, wherein an arrangement form of the plurality of holes is the same as that of the plurality of reflection patterns.

A light-transmitting resin member is provided that can inhibit color appearance in which the light-transmitting resin member appears to be colored depending on a viewpoint position. Provided is a light-transmitting resin member, in at least a part of a surface of which a plurality of groove structures configured with a plurality of linear protrusion portions and a plurality of linear recess portions are formed and in which the linear protrusion portions and the linear recess portions extend in directions parallel with each other and the grooves are formed at a pitch at which transmittance of visible light incident at an incident angle in a predetermined range becomes approximately constant, the visible light being incident on a region, in which the grooves are formed, in the surface, the visible light being transmitted through the light-transmitting resin member.

A vehicle exterior component includes: a plate-shaped base material having translucency that visible light is transmitted therethrough; a front surface coating film covering a front surface of the base material directed to front; and a light-absorbing film provided on a rear surface of the base material directed to rear and including an opening portion exposing at least part of the rear surface. The rear surface of the base material includes: an adhesion surface to which the light-absorbing film is adhered, and an exposed surface exposed through the opening portion. The exposed surface is rougher than the adhesion surface.
