Abstract
A light-absorbing composition according to the present invention includes: a light absorber; a curable resin; and an alkoxysilane. The alkoxysilane includes a dialkoxysilane. Since the alkoxysilane of the light-absorbing composition includes the dialkoxysilane, desired flexibility is likely to be imparted to a light-absorbing layer owing to an organic functional group of the dialkoxysilane while a strong skeleton having a siloxane bond is formed in the light-absorbing layer.
Claims15
A light-absorbing composition comprising:
- a light absorber;
- a curable resin;
- and
- an alkoxysilane, wherein
- the alkoxysilane includes a dialkoxysilane and a content of the dialkoxysilane in the alkoxysilane is 15 to 48% on a mass basis when a mass of the alkoxysilane is calculated as a mass of a complete-hydrolysis-condensation product of the alkoxysilane.
