摘要:
A process for producing a cationic emulsion stable to alkalis having an average particle diameter of 0.01 to 0.1 micron, in which, using as an emulsifier, a water-soluble polymer A2 obtained by subjecting a polymer A1 obtained by copolymerizing an amino group-containing compound with a compound copolymerizable therewith in the presence of a polymerization initiator, to neutralization with an organic or inorganic acid, a specific epoxy group-containing acrylate compound (c) and a compound copolymerizable therewith are subjected in combination to emulsion polymerization in the presence of a redox catalyst system in water as a medium to obtain an emulsion D; the emulsion D is then reacted with epichlorohydrin. The cationic emulsion is coated on paper, a film, or a strongly alkaline substrate to impart water resistance.

摘要:
There is a method and an apparatus for reading an image in which the light emitted from a light source through an original is converted into an electric signal by a photoelectric converting device and is outputted as an image singal. In this method, a compensation light is radiated onto the photoelectric converting device and thereby causing a compensation signal to be generated therefrom; this compensation signal is stored into a memory; an original image is then read; and the read signal is compensated by the compensation signal stored in the memory. The compensation light corresponds to each intensity of lights which are obtained through a reference original to be read and which are received by the photoelectric converting device. By use of this method in an original reading section of a facsimile apparatus or the like, an ununiformity and a variation in signal of each bit which is read by the photoelectric converting device are compensated, so that a stable output image signal can be derived.
