    摘要： A light-sensitive composition containing a polymerizable compound having at least one ethylenically unsaturated group, and a photopolymerization initiator of general formula (I): ##STR1## wherein Y represents --COOR.sub.1, ##STR2## --R.sub.3 --COOR.sub.1, --R.sub.3 --CONHR.sub.1 or --NHCO--R.sub.4 (wherein R.sub.1 represents a hydrogen atom, an alkyl group, or an aryl group; R.sub.2 represents a hydrogen atom or a methyl group; R.sub.3 represents an alkylene group; R.sub.4 represents an alkyl group, an alkoxy group, an aryl group; and l and m respectively represents integers of 1 to 10.); Ar represents a phenylene, naphthylene or heterocyclic aromatic group; X represents a chlorine atom or a bromine atom; and n represents 1 or 2.The light-sensitive composition has a good stability over time since crystallization of the photopolymerization initiator on the surface of the light-sensitive layer is inhibited.

    摘要： An electrophotographic light-sensitive material is described. The material is comprised of an electrically conductive support and a light-sensitive layer on the support. The light-sensitive layer contains a copolymer comprising: (a) vinylidene chloride or vinyl chloride; (b) a vinyl based unsaturated monomer represented by the general formula: CH.sub.2 =C(R.sub.1)(R.sub.2) (wherein the symbols are as defined in the appended claims); and (c) a vinyl monomer containing a hydroxyl group at the side chain thereof. This light-sensitive layer exhibits good adhesive properties, is superior in durability and moisture resistance, and produces images free from white spots and fog.

    摘要： A bundle of rays is incident in a lens array and converted into sub-bundles of rays. The sub-bundles of rays are separated by a color separator into first and second sub-bundles of rays of different colors. The first and the second sub-bundles of rays are combined by other lens arrays into a first and a second bundle of rays of uniform illuminance, respectively. The first and second bundle of rays of uniform illuminance are applied polarization beam splitting and then polarization angle conversion by polarization converters, to be converted into first and second linearly polarized beams, respectively. The second linearly polarized beams are separated by a color separator, provided on an optical path of the second linearly polarized beams, into third and fourth linearly polarized beams of different colors. The first, third and fourth linearly polarized beams are modulated by liquid crystal display devices, provided on optical paths of the first, third and fourth linearly polarized beams, respectively, with input video signals into first, second and third modulated beams. The first, second and third modulated beams are combined by a color combiner into a combined bundle of rays to be projected for displaying images carried by the video signals.
