The present disclosure describes, in part, an enzyme-mediated radical initiating system and methods of using the system to produce polymers, including polymeric hydrogels, at ambient conditions.

There are provided a photosensitive resin composition, a cured product thereof, and a wiring structure body, an electronic component, a semiconductor device, and a camera module each including the cured product. This photosensitive resin composition is cured by irradiation with active energy rays, instead of by heat treatment at high temperatures. In this photosensitive resin composition, film loss after a development process is restrained. Furthermore, a miniaturized pattern can be accurately formed by photolithography. An aspect of the present invention is a photosensitive resin composition including components (A) to (C): (A) a modified polyphenylene ether represented by formula (1) and formula (2), (B) a silsesquioxane compound represented by formula (3), and (C) a photopolymerization initiator, a cured product thereof, and a wiring structure body, an electronic component, a semiconductor device, and a camera module each including the cured product.

Provided is a composition which has excellent temporal stability and excellent spectral characteristics, and with which a film with suppressed defects can be formed. The composition includes a coloring agent represented by Formula (1) and a curable compound, in which R.sup.1 to R.sup.4 each independently represent a substituent, R.sup.5 represents an aliphatic hydrocarbon group, R.sup.11 to R.sup.15 each independently represent a hydrogen atom or a substituent, and Y.sup.1 and Y.sup.2 each independently represent a hydrogen atom or a substituent. However, at least one of R.sup.11, R.sup.12, R.sup.13, or R.sup.14 is a substituent or each of R.sup.11 to R.sup.15 is a hydrogen atom.

The present invention relates to an optical article, and an optical filter and an imaging device including the same. The optical article comprises: a near-infrared absorption glass substrate including a divalent copper ion as a chromatic ingredient; and a pigment dispersion layer formed on one surface or both surfaces of the near-infrared absorption glass substrate and having a near-infrared absorption pigment and an ultraviolet absorption pigment dispersed across the resin matrix thereof. Provided with a first and a second transmission cut-off region, the optical article has the advantage of allowing the fabrication of an excellent near-infrared cut-off filter that can effectively block light in near-infrared and ultraviolet bands and does not permit a difference in color sense with the change of incident angles.
