Title:
NEAR INFRARED RADIATION-ABSORBING COMPOSITION, NEAR INFRARED RADIATION CUT-OFF FILTER AND PRODUCTION METHOD THEREFOR, AND CAMERA MODULE AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2015/002117
Kind Code:
A1
Abstract:
Provided are: a near infrared radiation-absorbing composition capable of forming a cured film exhibiting excellent heat resistance while maintaining excellent near-infrared-radiation shielding properties; a near infrared radiation cut-off filter and a production method therefor; and a camera module and a production method therefor. This near infrared radiation-absorbing composition includes a copper compound obtained as a result of a reaction between a copper component and a siloxane (A1) including an acid group or a salt thereof.
