Abstract

The thermoreactive composition of the present invention contains: at least one kind (α) of cyanine compounds, a resin (β) having at least an ethylenically unsaturated bond and a hydrophilic group, and a thermal polymerization initiator (γ) . The resin (β) preferably contains a unit represented by the following general formula (I-1), a unit represented by the following general formula (I-2), and a unit represented by the following general formula (I-3). The thermal polymerization initiator (γ) is preferably an azo thermal polymerization initiator. In the following formula, X 1 , Y 1 , R 1 ~R 4 Refer to the manual for the definition.

Description

technical field [0001] The present invention relates to a thermally reactive composition comprising a cyanine compound, a resin having an ethylenically unsaturated bond and a hydrophilic group in one molecule, and a thermal polymerization initiator, and a wavelength cutoff using the thermally reactive composition filter. Background technique [0002] The sensitivity of solid-state imaging elements (CCD, C-MOS, etc.) used in digital cameras, video cameras, mobile phone cameras, etc. ranges from the ultraviolet region to the infrared region of the wavelength of light. On the other hand, human visibility is only in the visible region of the wavelength of light. Therefore, by providing an infrared cut filter between the imaging lens and the solid-state imaging element, the sensitivity of the solid-state imaging element is corrected so as to be close to human visibility. [0003] As an infrared cut filter, there are known reflective filters that combine layers containing substa...
