Abstract

A neon light absorbing film with a neon light absorbing adhesive layer of adhesive agent that so as to avoid changing of neon light absorptivity between before and after aging operation subsequent to coating drying, is a polymer with satisfactory crosslink density even immediately after coating drying, in which a neon light absorbing dye represented by a cyanine dye is stabilized by means of an additive, etc. to thereby retain excellent stability even in a heat resistance test or wet heat resistance test and keep the haze value thereof low. Further, there is provided an optical filter utilizing the film. Combining of an adhesive agent composed of a thermally crosslinkable acrylic aliphatic resin of 1,000,000 or higher weight average molecular weight and a crosslinking agent, a cyanine neon light absorbing dye and a clay mineral has led to the developments of a neon light absorbing film with a neon light absorbing adhesive layer retaining excellent stability even in a heat resistance test or wet heat resistance test and keeping the haze value thereof low and an optical filter utilizing the film.

The ultraviolet light emitted by the rare gas in the slurry state is emitted to the illuminant which is discharged to the wall surface treatment, so that the visible t which is necessary for the image can be generated, and the near-infrared rays which are harmful to the human body at the same time as the visible light are generated, and the milk is present. Together, the wavelength of the red light color is reduced to a wavelength of about 595 nm, and the t-stone 1 value is the first line (the following table is not a twilight), etc.: magnetic waves, although beneficial to visible light However, it is necessary to shield the electromagnetic waves that are woven by oxygen, near-infrared, and harmful to the human body, so optical filters are required. (Matt. Patent Document 1) The member used in the optical filter is used in accordance with the metal material. The entanglement of the near-infrared rays and the electromagnetic waves harmful to the human body can be simultaneously cut off (Metro, Patent Documents 2 and 3). For the ambience, it is necessary to additionally provide an absorbing layer. Previously, the following light is used: a light-absorbing specific pigment is added to the absorbing film obtained by applying the varnish resin 2 to the transparent substrate, and has a shadow near Red 1 线 ί The substrate of the electromagnetic wave function, as well as the anti-glare and anti-reflection film, etc., are bonded together by the adhesive to form wells: grinding water to filter the first film.
