Abstract
A UV-IR-absorbing composition according to the present invention includes: an absorber formed by a phosphonic acid represented by the following formula (a) and copper ion, the absorber being dispersed in the UV-IR-absorbing composition; a phosphoric acid ester allowing the absorber to be dispersed; a matrix resin; and an alkoxysilane monomer.
Claims14
An ultraviolet- and infrared-absorbing composition comprising:
- an absorber formed by a phosphonic acid represented by the following formula (a) and copper ion, the absorber being dispersed in the ultraviolet- and infrared-absorbing composition:
- wherein R11 is a phenyl group, a nitrophenyl group, a hydroxyphenyl group, or a halogenated phenyl group in which at least one hydrogen atom of a phenyl group is substituted by a halogen atom;
- a phosphoric acid ester allowing the absorber to be dispersed;
- a matrix resin;
- and
- an alkoxysilane monomer.
