A compound represented by the following general formula (I): (the symbols in the general formula (I) are as described in the Description),

Compound and intermediate thereof

An optical material of the present invention has a minimum transmittance value in a wavelength range of 445 nm to 470 nm of a transmittance curve measured at a thickness of 2 mm of the optical material.

Optical material and use thereof

The cooking control device is installed on a moving object and is configured to communicably connect to a plurality of content display devices and one or more cooking apparatuses, each of the content display devices configured to playback content on a screen. The cooking control device comprises a processor and a transmitter. The processor receives content playback information for the plurality of content display devices respectively, determines one or more of the plurality of content display devices that finish playback of content within a given time based on the content playback information, and produces a preparation/cooking instruction for the one or more cooking apparatuses according to a number of the one or more of the plurality of content display devices. The transmitter transmits the preparation/cooking instruction to the one or more cooking apparatuses.

Cooking control device, cooking control system, and cooking control method

An optical material of the present invention has the following characteristics (1) to (4) in a transmittance curve which is measured at a thickness of 2 mm of the optical material.

The present invention is to provide a color material with excellent dyeing property and excellent heat resistance, and a method for producing the color material, which is able to obtain the color material with high purity and at high yield. Disclosed is a color material represented by the following general formula (I): (symbols in the general formula (I) are as described in the Description.)
