Abstract: The invention discloses a photopolymerizable composition comprising at least one, ethylenic unsaturated bond-containing compound, a hexaaryl-biimidazole compound, and an organoboron compound represented by a specific general formula; and discloses a photosensitive thermal recording material having a recording layer that contains the photopolymerizable composition. The photopolymerizable composition and the photosensitive thermal recording material of the invention are highly sensitive to UV rays and visible to IR rays falling within a wavelength range that includes wavelengths not longer than 450 nm, and are effective for decoloring a dye component that absorbs the rays falling within the wavelength range.

Abstract: A color filter having a light-transmissive support and two or more color-developing layers, which develop hues differing from each other, laminated on the support. Each color-developing layer is developed into a predetermined color pattern including pixels. The pixels of the developed color patterns of the layers either overlap in a direction of lamination or do not overlap in the direction of lamination. Also provided are a color filter forming material produced by laminating the two or more photosensitive and heat-sensitive color-developing layers on the light-transmissive support, and a process for producing a color filter by exposing each photosensitive and heat-sensitive color-developing layer of the above color filter forming material to form a predetermined pattern, heating the photosensitive and heat-sensitive color-developing layers, and fixing the developed color patterns.

Abstract: An inkjet recording sheet comprising a support, on the support, a colorant-receiving layer including a phenolic compound and at least one organic mordant selected from the group consisting of a polyallylamines and their derivatives, a polyvinylamine and their derivatives.

Abstract: The present invention provides a recording material comprising a support, a recording layer provided on the support, and at least one protective layer provided on the recording layer, wherein, the recording layer contains a coloring component A encapsulated in heat-responsive microcapsules, and a substantially colorless compound B, which is outside the heat-responsive microcapsules and has a coloring site that colors when reacted with the coloring component A, and wherein, at least one of the protective layer or a layer adjacent thereto comprises a layer containing titanium oxide.

Abstract: A light and heat sensitive material comprising, on a support, a light and heat sensitive recording layer containing a color-developing component A encapsulated in a thermally responsive microcapsule and a photopolymerizable composition containing a substantially colorless compound B having at least a polymerizable group and a portion which reacts with the color-developing component A to develop a color in the same molecule and a photoinitiator outside of the thermally responsive microcapsule, and non-color-developing layers containing a swellable inorganic layer compound.

Abstract: The support member for photographic printing paper of the present invention has a coating layer which comprises white pigment and hydrophobic binder soluble in an organic solvent on a base material, whereby voids are formed in said coating layer. The support member increases whiteness degree and gives an image with excellent sharpness.
