摘要:
Diclosed is a polymer having a group represented by the following formula (I) or (II) in a main chain consisting of carbon-carbon bonds: [wherein x is an oxygen atom, a sulfur atom or N-R¹,R¹ is a hydrogen atom, an alkyl group containing 1 to 3 carbon atoms or CH₂CO₂H.] said group being decarboxylated by photo-reaction of its own or by photo-reaction with a photosensitizer which absorbs a light to generate a free radical.

摘要:
Disclosed is a photopolymerizable compostion which is very sensitive to light, especially visible light having a wave length of 600 to 700 nm. The photopolymerizable composition comprising a polymerizable compound having an ethylenically unsaturated double bond and a photopolymerization initiator wherein the photopolymerization initiator comprises (a) a specific sensitizer and (b) a radical forming agent.
摘要:
Disclosed is a photosensitive composition for volume hologram recording which is used for recording an interference fringe produced by a laser beam or a light having excellent coherence, as fringes having different refractive index. The composition comprising:
(a) a cationic polymerizable compound which is liquid at ambient temperature; (b) a radical polymerizable compound; (c) a radical photopolymerization initiator composition sensitized by a laser beam or a light having excellent coherence which has a specific wavelength to polymerize the ingredient (b); and (d) a cationic photopolymerization initiator composition which shows low photosensitivity to the light having a specific wavelength and is sensitized by a light having the other wavelength to polymerize the ingredient (a), wherein an average refractive index of the ingredient (a) is smaller than that of the ingredient (b). A process for producing the photosensitive composition is also disclosed.
