摘要： PURPOSE:To enhance sensitivity by using metal-free phthalocyanine specified in crystal form as a pigment in the photoelectrophoretic display element which holds a liquid suspension contg. fine pigment particles between two transparent electrodes. CONSTITUTION:Fine particles of metal-free phthalocyanine (Pc) of a tau type, modified tau type, eta type, and/or modified eta type are suspended in an insulating solvent, a transparent electrode 2 formed on a glass base 1 is coated with this obtained coating suspension, and further on this layer 3, a roll electrode 4 subjected to surface insulation treatment is provided to obtain an objective display element. The tau or modified tau type metal-free Pc is obtained by heating and agitating alpha-type Pc and causing transition of the crystal form. The eta and modified eta type metal-free Pc is obtained by heating and agitating a mixture of the alpha-type Pc and metal-free Pc having a substituent on its benzene ring.

摘要： PURPOSE:To increase the sensitivity over a wide wavelength range by combining a specified charge generating substance with a specified charge transferring substance. CONSTITUTION:In an electrophotographic receptor, a mixture or 1pt.wt. of copper phthalocyanine pigment with 0.1-10pts. oxazole deriv. represented by structural formula A is used as a charge generating substance, and trinitrofluorenone represented by structural formula B is used as a charge transferring substance. A layer of the charge generating substance having 0.5-5mum thickness and a layer of a charge transferring substance having 8-30mum thickness are laid on an electrically conductive support. Copper phthalocyanine has photosensitivity in the red region and said oxazole deriv. has photosensitivity in the blue region. When they are mixed, the photosensitivity in the red region is increased by about 1.5-2 times and the mixture has high sensitivity in 500-825nm, so it is suitable for a semiconductor laser light source.

摘要： PURPOSE:To obtain an electrophotographic plate especially excellent in durability and abrasion resistance, by using a binder resin containing a specified thermosetting acrylic polymer for a charge transfer layer. CONSTITUTION:A thermosetting polymer used as a binder is polymerized from >=1 monomers selected from a group of monomers represented by the formulaI in which R1 is H, CH3; X1 is -COOR2; R2 is H, 1-4C alkyl or 2-ethylhexyl, and a monomer represented by formula II in which R2 is H, CH3; X2 is a group represented by the formulas III, IV, or V, R4 being H or 1-4C alkyl, and R5 being H or CH3. An amine compound having a triazing ring represented by the formula VI or an epoxy resin or the like is used as a hardening agent. A charge transfer substance represented by the formula VII is contained together with said binder and said hardening agent in a charge transfer layer, thus forming a composite type electrophotographic plate. This plate has high surface hardness and abrasion resistance, and superior durability.

摘要： PURPOSE:To enhance the residual potential characteristics and to obtain high sensitivity by forming a layer contg. phthalocyanine pigment as a charge generating substance and a layer contg. a mixture of an electron donative substance with an electron accepting substance as a charge transferring substance on an electric conductor layer and carrying out specified charging and exposure processes. CONSTITUTION:Nonmetallic or metallic phthalocyanine pigment is stuck to an electric conductor layer by coating, vapor deposition or other method, or it is dispersed in a high molecular compound to form a charge generating layer on the conductor layer. A charge transferring layer contg. an electron donative substance such as a high molecular compound contg. a carbazole ring or an anthracene ring and an electron accepting substance such as nitrofluorenones or a benzoquinone compound is then formed on said charge generating layer to manufacture an electrophotographic plate. The surface of this plate is positively light of 500-800nm to erase the surface charges. Thus, an electrophotographic plate with high sensitivity and favorable repeating characteristics and a record are obtd.

摘要： PURPOSE:To improve sensitivity and spectral characteristics for visible rays by using CdSe as charge generating material and one or more kinds out of the group of triphenyl oxazole compound, styryl dye base and cyanine dye base as charge transfer material. CONSTITUTION:CdSe is stuck on a conductive substrate to about 0.1-5mu film thickness to form a charge generating layer. Next, a charge transfer layer is formed to about 5-50mu thickness by such a method of coating the coating solution prepared by mixing about 0.5-10pts.wt. binder resin to 1pt.wt. one or more kind of compounds selected from the group of triphenyl oxazole compounds, styryl dye base or cyanine dye base on the said charge generating layer, whereby an electrophotographic plate is made. After this photographic plate is charged to negative, it is exposed with images and is developed. The said three kinds of the compounds have high sensitivity to 400-700nm wavelengths and since CdSe generates holes, the good sensitivity and spectral characteristics may be obtained by making primary charging negative.
