Abstract: PURPOSE: To relieve the influence of a filter material, and enhance contrast by controlling an external light reflecting quantity of filters by controlling the area of hole parts. CONSTITUTION: A black matrix 20 of a black pigment particle is formed on an inside surface of a face plate 10 of a transparent base board, and blue, green and red filters 30, 40 and 50 are formed in these hole parts. Blue, green and red color phosphor layers 34, 44 and 54 are formed on these filters in response to the hole parts. In respective visibility of blue, green and red color light emitting phosphors, since green is the largest, a hole part 22G in which the green filter 40 and the green color light emitting phosphor layer 44 are formed is made smaller by 10% in its area than hole parts 22B and 22R in which the blue and red filters and the phosphor layers are formed. In this way, since a quantity reflected by the external light is reduced by controlling the area, a contrast characteristic can be improved more than when the areas of the hole parts 22G, B and R are equal to each other.

Abstract: PURPOSE: To prevent a color mixture while manufacturing a filter pattern with a simple process as compared with the conventional process by reforming a method of forming a pigment layer. CONSTITUTION: A filter pattern is manufactured by a process as follows. (1) After a solution containing the first pigment particle 3 (blue color) is applied to be dried on a substrate 1, a photoresist liquid is applied to be dried on this solution, to form a laminated structure of a resist layer 4 and a pigment layer 3. (2) This laminated structure is hardened by an exposure 5 into a prescribed pattern, thereafter developed to form a laminated pattern (3-4). (3) The processes 1 and 2 are repeated relating also to the other first pigment particle 6 (green color), to form a laminated pattern (6-7; 7 resist layer). (4) A solution containing the second pigment particle 8 (red color) is applied to be dried on the substrate 1 and a laminated pattern (3-4 and 6-7), thereafter to apply a release agent, and by releasing the resist layers 4, 7 with the second pigment layer 8 on there layers 4, 7, the first (3, 6) and the second (8) pigment layers are formed.

Abstract: PURPOSE:To provide the antireflection effect over a wide band by introducing dyestuff into the lower layer film of two-layered antireflection films and optimizing the spectral transmittance and spectral reflectivity thereof. CONSTITUTION:The dyestuff is incorporated into the 1st thin film of the antireflection films consisting of the 1st thin film formed on a substrate and the 2nd thin film formed on this 1st thin film. In addition, the antireflection films are so formed as to satisfy the relation expressed by equation when the wavelength at which the spectral reflectivity in the visible light region of the antireflection films is minimized is designated as lambdar and the wavelength at which the spectral transmittance is minimized as lambdat. For example, the upper layer film of the antireflection films is formed of an SiO2 film obtd. by hydrolysis and dehydration condensation of Si(OC2H5)4 and the lower layer film is formed of a film constituted by incorporating the dyestuff into a TiO2-SiO2 film obtd. by hydrolysis and cocondensation of Ti(OC37)4 and Si(OC2H5)4 in such a manner that the prescribed spectral transmittance is attained. A liquid prepd. by dispersing Hoster Perm Pink E into isopropyl alcohol is used as the pigment dispersion of a lower layer forming soln.

Abstract: PURPOSE:To increase the transfer efficiency of recording signals by specifying the aspect ratio, coercive force and volume content of hexagonal ferrite powder in a magnetic recording layer. CONSTITUTION:It is specified that the hexagonal ferrite powder in the magnetic recording layer has 3 - 6 aspect ratio, >= 1500, Oe coercive force and >= 40 % volume content. If the temp. coefft. of the coercive force Hc is positive (Hc increases with temp.), an equal effect of recording to a medium having larger coercive force Hc can be obtained with the medium of this invention by performing contact magnetic transfer at higher temp. than the recording temp. Moreover, if the temp. coefft. of coercive force of a slave tap is negative, difference of coercive force between the mother tape and the slave tape further increases. Thereby, the transfer efficiency of recording signals is increased and the reproduction output is extremely increased.

Abstract: PURPOSE:To obtain a good surface characteristic and electromagnetic conversion characteristics by incorporating a resin having a sulfone group, etc., and a resin having a basic group and/or surfactant having a basic group into a magnetic layer. CONSTITUTION:The magnetic layer is so formed as to contain the resin having the sulfone group and/or the group of the metal salt of the sulfonic acid and the resin having the basic group and/or the surfactant having the basic group. The sulfone group, etc., bond to the magnetic powder in a pulverized state, more particularly superfine hexagonal magnetic powder to disperse the fine particle; further the reflocculation after the primary pulverization is prevented by the resin or surfactant having the basic group. A magnetic coating compd. having high dispersibility and high stability is thereby supplied and the magnetic recording medium which has high output and is free from coated film defects such as blobs and streaks is obtd.

Abstract: PURPOSE:To obtain a cathode ray tube provided with a film stable in electrification-proof performance by forming a SiO2 film from Si alcoholate on an external surface of a face plate. CONSTITUTION:A continuous SiO2 film is formed on an external surface of a face plate of a cathode-ray tube by coating and firing of Si alcoholate in processes of dipping and spin-coating and the like. This SiO2 film is preferably made 0.04mum or more and 0.15mum or less in thickness. This SiO2 film is earthed for use. Hence, a cathode-ray tube provided with an electrification-proof film, which is stable in electrification-proof performance, can be obtained with easy manufacture.
